ring and inner ring, needle rollers and a cage that guides the
rollers. In this bearing, the cage or needle rollers are guided by the
rib or side plate of the outer ring. Consequently, the roller and
cage assembly cannot be separated from the outer ring. When the
user wants to use the shaft as the raceway surface, NTN can offer
a variant without an inner ring.
Available in both metric dimensions and inch dimensions.
This product is best-suited to a space-saving design due to its
