Mounting instructions

drylin® linear bushings in 03 Design Series offer great advantages in applications with parallel shafts. They compensate for alignment and parallelism errors by their geometry and should be used on the shaft located furthest from the drive mechanism.

The design provides a spherical area on the outer diameter of the aluminum adapter for self-alignment. Reductions in load capacity are prevented, since the shaft always lies on the total projected surface.

Thanks to the even load distribution over the entire bearing, edge loads are not possible with self-aligning drylin® R linear bearings. Even in unfavorable conditions, the load is supported by the entire projected surface.

In order to compensate for parallelism errors between two shafts, the outer diameter is designed to be smaller than the housing bore diameter by 0.2 to 0.3 mm (depending on the size). With the use of mounted O-rings, these bearings have an elastic bearing seat. The overdimension allows for maximum compensation shaft misalignments.

drylin® R self-aligning bearings are delivered hard anodized. These surfaces guarantee the highest wear resistance if the aluminum bearing moves in the housing during compensatory adjustments.

The spherical drylin® adapters can compensate for alignment errors. A hard-anodization protects the aluminum adapter from wear.

With built-in clearances and the use of O-rings, the self-aligning drylin® R bearings from the 03 Design Series can compensate for parallelism errors.

Self-aligning drylin® R bearings from the 06 LL design series can compensate for parallelism errors up to +/- 12 inches (3 mm).
