5.2 Lubricant selection/lubricant table

5.2.1 General information on selecting the oilUnless a special arrangement is made, SEW-EURODRIVE delivers the drives withoutoil. This does not apply to auxiliary drives and primary gear units.

The following tables provide an overview of mineral and synthetic oils.

Mineral oilStandards Lubrication oils are divided into ISO VG viscosity classes according to ISO 3448 and

DIN 51519.

Synthetic oilStandards Lubrication oils are divided into ISO VG viscosity classes according to ISO 3448 and

DIN 51519.

INFORMATIONThe oil viscosity and type (mineral/synthetic) to be used are determined by SEW-EURODRIVE specifically for each order. This information is noted in the orderconfirmation and on the gear unit's nameplate. Any deviation from these conditionsrequires consultation with SEW-EURODRIVE.

INFORMATIONThis means the gear unit must be filled with the correct oil grade and quantity beforestartup. You may find the corresponding information on the nameplate of the gear unit.

5 Lubricant selection/lubricant tableLubrication, Cooling and Heating

In addition to the required viscosity, the oil must fulfill the following criteria:• CLP oils according to DIN 51517-3• Micro-pitting test according to FVA, FV no. 54/ I-IV, GFT class high, damage force

level >10

If synthetic oil is used, SEW-EURODRIVE recommends polyalphaolefin-based oil(CLP HC).

5.2.2 Permitted lubricants

Key to the lubricant tableThe lubricant table shows the permitted lubricants for SEW-EURODRIVE gear units.This information is provided to preselect the lubricant. The proper and final lubricantselection is made by SEW-EURODRIVE to match the specific project. Consider theused abbreviations, meaning of shading and notes.

INFORMATIONObserve the operating temperature of the gear unit when specifying the oil changeintervals.If required, a cooling system must be used or the oil change interval must be shortened(see "Lubricant Change Intervals" in the "Helical and Bevel-Helical X.. Series GearUnits operating instructions).

INFORMATION• The standard for viscosity and oil grade is the type of oil that is specified by SEW-

EURODRIVE on the order (see order confirmation and nameplate).• Consult SEW-EURODRIVE if you use bio and food grade lubricants or polyglycol

oils.• Check the compatibility of the greases and oils used.

CLP = Mineral oilCLP HC = Synthetic polyalphaolefinE = Ester oil (water hazard classification 1)

= Mineral lubricant = Synthetic lubricant

3) = Lubricants may only be used if service factor Fs ≥ 1.3 4) = Take into account critical startup behavior at low ambient temperatures6) = Ambient temperature

= Lubricant for the food industry (food grade oil)

= Biodegradable oil (lubricant for agriculture, forestry, and water management)OilOil

Motor pump /ONPWith pressure lubrication, a motor pump supplies all bearing points and gearing abovethe oil sump with oil via internal piping. A motor pump is used, for example, if the required speed of the shaft end pump (> 400rpm) is not reached. It is also used in an inverter operation where a shaft end pumpcannot be used or can only be used under certain circumstances.The motor pump is mounted externally to the gear unit and depends on the speed of thegear unit.

Structure The figure shows an example of a motor pump.

The motor pump is shipped as a complete unit but without electrical connections.The basic motor pump includes the following components:• Directly connected asynchronous motor (pump is always running)• Oil filter with filter element and electrical/optical contamination indicator• Pressure switch that monitors the pump pressure. Warning or switch-off signal when

the oil pressure reaches < 0.5 bar• Option: Temperature switch with trip point for monitoring the cooling group, i.e.

warning or gear unit shutdown when the oil temperature exceeds 194°F.

The following pump mounting types are available:• Directly mounted on the gear unit, including piping• On the mounting frame, for separate installation, but without piping to the gear unit

The customer has to connect the wiring for the following items:• Pressure switch to the customer's evaluation unit• Electrical contamination indicator of the oil filter• Pump motor• Option: Between temperature switch and pump motor

Notes on connection and operation

To achieve the thermal ratings listed in the selection tables (beginning on page 142),different flow rates of the cooling water are necessary, depending on the size, mountingposition, and type of lubrication. The following table lists the approximate values for theflow rates required for the M5 mounting position (water inflow temperature 60°F).

The table lists the flow rate of the cooling water for one cartridge. When using twocartridges, the flow rate shown below should be doubled.

The cooling circuit must be connected in parallel for gear units with two water coolingcartridges, as shown below.

INFORMATIONContact SEW-EURODRIVE when using a different flow rate, a different watertemperature, a special cooling media, or an aggressive cooling media (such asbrackish water or salt water), since they affect the cooling capacity of the cartridge.

5.4.4 Circulation cooling: oil-water cooler with splash lubrication /OWCAn oil-water cooler can be used if a naturally-cooled gear unit or a gear unit with a fanon the input shaft has an insufficient thermal rating. However, appropriate cooling watermust be available on site.

Structure SEW-EURODRIVE uses two different types of heat exchangers:• Plate Exchanger:

For gear unit sizes X140 to X170, a plate heat exchanger is used for oil supplysystems OWC 005/015/025.

INFORMATION• Contact SEW-EURODRIVE if a chemically aggressive cooling media, such as

brackish or salt water, is used.• The following information applies to gear units with splash lubrication. The cooling

system with a motor pump only cools the gear unit oil. It does not provide pressurelubrication.

• When installing a filter in the OWC cooling system, there should be sufficient heightfor removing the filter element and the filter hood.

Notes on the installation and connection

The user must provide a low-vibration installation that is no more than 3 feet from thegear unit. The cooling system should be at the same level as the gear unit or lower. Ifthis is not possible, contact SEW-EURODRIVE.The cooler must be installed in such a way that input and output air flow is notobstructed. There should also be sufficient ventilation and protection against dirt. Thefollowing procedures are required when connecting the cooling system:• Avoid a short circuit in the cooling circuit. The suction and pressure lines must be

installed on the gear unit as far apart as possible.• Do not reduce the recommended cable cross section, as shown on the next page.• Choose the correct wall thickness and material when selecting pipes, hoses and

screw fittings. Preferably, use composite material seals.

As standard, the oil-air cooling system is delivered in the design as illustrated below. Theconnections of the cooling system are located on the lefthand side of the system. Inorder to keep the cable lengths to the gear unit as short as possible, the suction andpressure connection should be aligned towards the gear unit during installation. Ifnecessary, the connections can be moved to the other side. To do so, loosen the pumphead [1] and the register [2], rotate them by 180°, and re-attach them.

5.4.7 Circulation cooling: oil-air cooler with pressure lubrication /OAPAn oil-air cooling system can be used if the thermal rating of the naturally-cooled gearunit or a gear unit with a fan on the input shaft is insufficient.

Structure The figure shows an example of an oil-air cooler with motor pump with pressurelubrication.

The cooling system is delivered as a complete unit on a mounting frame but withoutelectrical wiring and piping.The standard design of the basic cooling system contains the following items:• Pump with directly mounted asynchronous motor• Oil-air heat exchanger• Oil filter with filter element and electrical/optical contamination indicator• Pressure switch that monitors the pump pressure. Warning or switch-off signal when

the oil pressure reaches < 0.5 bar• Temperature switch with two switching points for the following:

• Controlled startup of the fan motor with an oil temperature > 104°F• Monitoring of the cooling group, i.e. warning or gear unit shutdown when the oil

temperature exceeds 194°F.

INFORMATIONThe following versions apply to gear units with pressure lubrication. The coolingsystem with motor pump cools the gear unit oil and provides the pressure lubrication.

Notes on the installation and connection

As standard, the cooling system must be set up separately from the gear unit. As anoption, the cooling system can be delivered mounted directly to the gear unit. Thecooling system is delivered with piping, but without wiring.The user must provide a low-vibration installation that is no more than 3 feet from thegear unit. In addition, the cooling system should be at the same level as the gear unit orlower. If this is not possible, contact SEW-EURODRIVE.The cooler must be installed in such a way that input and output air flow is notobstructed. There should also be sufficient ventilation and protection against dirt. Thefollowing procedures are required when connecting the cooling system:

• Do not reduce the indicated cable cross section.• Choose the correct wall thickness and material when selecting pipes, hoses and

screw fittings. Preferably, use composite material seals.

SEW-EURODRIVE recommends the following cable cross sections for connecting thecooling system to the gear unit and the cooling circuit:

INFORMATION• It is essential that the heating elements are fully immersed into the oil sump to

prevent damage.• The position of the thermostat and the temperature sensor varies with the design

and the mounting position of the gear unit.• The usage and the maximum number of heating elements depends on the gear unit

size, mounting position, end gear position, and type of lubrication.Some combinations of accessories are not possible, depending on the mountingposition and the mounting surface. Consult SEW-EURODRIVE.

• For dimensions of the oil heater, see page 443.

5 Oil heater /OHLubrication, Cooling and Heating

5.5.2 Notes on the function of the oil heater• The switching point of the oil heater thermostat is factory set to a temperature of

about 9°F above the respective limit temperature "without heater". The thermostatturns off the oil heater at this temperature. Only then may the gear unit be started. Ifthe temperature falls below the trip point by approximately 9°F, the thermostatreactivates the oil heater.

• Thermostat and oil heater are installed on the gear unit and are ready for operation,but they must be wired properly and connected to the external power supply beforestartup.

• Contact SEW-EURODRIVE if another oil viscosity is used or if the ambienttemperature falls below the specified limit temperature.
