Combined sliding and rolling for low drive forces

DryLin® hybrid bearings offer a unique self-lubricating combination of plain and rolling bearings. Integrated rollers achieve low drive forces while the sliding effect simultaneously protects against lateral forces. This combination makes DryLin® hybrid bearings ideal for manual adjustments such as machine and safety doors/guards, mobile control panels, and more. The efficiency of the zinc die-cast design also cuts costs. DryLin® hybrid bearings can be used on a variety of hard-anodized aluminum profiles available from the DryLin® W linear construction kit.

� Low driving force required� Smooth operation� Cost effective � Low-profilel Offset and abuse forces are easily absorbed by sliding

elements

Typical application areas:l Machine doors l Control panelsl Manual applicationsl Safety doors/guardsl Camera equipment

DryLin® W hybrid bearings type 01The DryLin® W hybrid bearings from the WJRM-01 series are

equipped with a plastic roller and plain bearing liner. Bearing

housings are available in 3 rail diameter sizes, and can be used

with DryLin® W single or double shaft rails. The hybrid bearing

should be installed so that the bearing load is applied in the

rolling direction. Other load directions are possible, but may

create greater friction forces.

DryLin® W hybrid bearings type 21The DryLin® W hybrid bearings in the WJRM-21 series are each

equipped with two bearing plastic rollers at an angle of 70° or

80°. Available in 3 sizes, they can be combined with DryLin® W

single and double shaft rails. The double roller bearings offer a

higher load capacity than the -01 version and helps to reduce the

friction force caused by cantilevered loads.
