KR19 KOYO NEEDLE ROLLER BEARINGS

KOYO Full Complement Yoke-Type Track Rollers – Metric Nominal Dimensions

JTEKT track rollers listed in this catalog have been designed with outer rings of a large radial cross section to withstand heavy rolling and shock loads on track-type or cam-controlled equipment. The outer diameters of the outer rings are either crowned or cylindrical. Crowned track rollers are designed to alleviate uneven bearing loading resulting from deflection, bending or misalignment in mounting.
Stud-type track rollers are available in various open designs, as well as with lip contact seals or metal shields.
