R linear 03 series plain bearings are self-aligning and offer great advantages in applications with parallel
shafts. They are able to compensate for alignment and parallelism errors and should be used on the shaft furthest
from the drive mechanism. The design provides a raised spherical area on the outer diameter of the aluminum
adapter for self-alignment. Load capacity is the same as the fixed version. Even in unfavorable edge-load 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 - 0.3 mm depending on size. With the use of mounted O-rings, these bearings
have an elastic bearing seat.
