The cage structure is made of an aluminium, brass, or steel flat bar with a chemical composition that guarantees relevant characteristics imposed on the linear bearing system.
Bearing cages are filled with definite number of friction-reducing needles, rolls or balls precisely fitted into cage holes.
Stiffness of rolling components
Rolling components with the dimensions:
Ball Ø 9, roller Ø 9 x 9, and 3 needles Ø 3 x 9 exhibit quite similar size of projections.
