4 - way equal load rating
The SRS bearings can be used for different applications in any position because each row of balls is arranged at a 450 angle. Consequently, the same load rating is applied to the bearing in all four direction (radial, reverse radial and both lateral directions).
The low cross-section height of the rail in SRS bearings and its compact design woth a single row of balls allows them to be installed in very limited spaces.
The SRS is a lightweight, low-inertia bearing made of resin formed using insertion molding in part of the LM block (eg. around the ball housing channel).
