This series of rolling bearings are especially studied for very specific applications. They are very compact and easy to use and suitable to support heavy radial loads and to slide with high precision in the special guideways which are predominantly used in automatic packing and transfer machines, as well as in translation systems.
The combined stud type track rollers are available only in sealed performance, long-life lubricated and therefore supplied grease filled.
The construction criteria of this series are the same as the ones of the normal LI-BE stud type track rollers with the exception, as shown here below, of the main stud which acts as a support while the inner raceway is given by an inner ring with special technological features.
Reference slots are provided on the main stud to avoid geometrical fitting errors.
