Abstract

In a linear rolling bearing element, especially for tripod joints, the cage is formed of a relatively thick sheet metal and limit projections for a linearly movable support are formed by stamping out of the material of the cage. The rollers are likewise held in the cage by projections formed out of the cage. This results in a stable cage which can take the high forces from the engagement of the support. The outer roller may be close to the limit projection, in order to assure a good support of the roller in the extreme position of the tripod joint.
