ClampsSolutions for Timing Belt Linear Drives
All timing belt linear drives require a clamp to transfer the belt motion to linear shuttle travel. BRECOflex clamps and tensioning clamps for Metric and English pitch belts ensure a solid attachment for utilization of full belt strength. Custom clamps are available in various materials and coatings.
• Standard Clamp
• Half Clamp
• Tensioning Clamp
Recommended Clamp types and Application Examples
Standard Clamp - used for connecting both belt ends together at the carriage
Half Clamp - used for connecting each belt end to the carriage or machine frame
Tensioning Clamp - used like a half clamp, but also to adjust tension in the system

ClampsAppendix
Tensioning Clamp Installation Notes
BAT and BATK Orientation
Custom clamps machined to print are available in various materials and surface finishes. Custom clamps modified from stock AL 6061, extruded clamps are available in as little as 8 days. Submit drawings or technical specifications to Applications Engineering for quotations.
Running direction must be specified for BAT and BATK pitches as follows:
Right-hand orientation Left-hand orientation
Right-hand orientationLeft-hand orientation
Plate at least 5 belt teeth into the clamp to achieve maximum strength. Bolt the clamp plates together sandwiching the belt. Refer to tensioner diagram for recommended initial tightening torque for the countersunk screws. Place the threaded tensioning rod through a hole on a mounted fixture. By tightening a nut on the threaded rod the tensioning clamp will pull the belt and apply tension. Refer to catalog B207 pg. 5 or the online calculator for recommended pretension. After applying the proper tension, install and tighten the 4 mounting bolts in their slotted adjustment holes to keep the clamp in position. Refer to tensioner diagram for recommended tightening torque for the cap screws and final torque for any countersunk screws. By doing this, the pressure will be relieved on the threaded rod. Properly mounted tensioning clamps transfer all of the forces onto the mounted bolts and do not rely on the threaded rod.

Tensioner IdlersSolutions for Fixed Center-Drives
All timing belt drives require some form of tension adjustment. Tensioner idlers are a common way to provide this adjustment while maintaining fixed centers for the remaining pulleys. Placement of the tensioner may be on the belt back or tooth side provided that minimum recommended diameters are observed. Tensioner idlers may also be used to route the belt in a drive or increase wrap on a small pulley for higher power transmission capability.
Back Bending Idler - Also known as Contra-flexure. Typically used to increase belt wrap on the drive pulley. Refer to appendix for minimum recommended pulley and idler sizes. Diameter recommendations differ for forward and back bending.
Tooth Sided Idler - Used for tensioning adjustment or routing belt. Idler may be flat or toothed type.
Standard material is a steel shaft and bearings with aluminum housing and flanges. Custom tensioner idlers or materials are available as modified items for small quantities and custom items for large quantities. Permanently greased bearings are used with max continuous temperature of 160° F and intermittent 240° F.
