Machined-ring needle roller bearings
This product mainly includes machined components — an outer 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
low section height,and large load capacity.
Another advantage is high rigidity and high bearing accuracy
due to the machined outer ring
This bearing can be used with a housing made of light metal,
because of its highly rigid outer ring. (Other than NKS small
size products)
The outer ring has a lubrication hole and lubrication groove.
Both single-row and double-row types are available.
A type with seal a installed on a single side or on both sides is
also available.
