Overview
Nachi 51230 Thrust bearing
Axial Deep Groove Ball Bearing, single direction with machined brass cage
The Nachi 51230 is a large single-direction thrust ball bearing with a 150 mm shaft washer bore, 215 mm housing washer outside diameter and 50 mm assembly height, guided by a machined brass cage. In the bigger sizes the cage carries real load from ball skidding and centrifugal effects, and machined brass handles that, along with heat and marginal lubrication, better than a pressed steel cage. The bearing takes pure one-way axial load and no radial load. Separable washers, non-angle-adjustable, rated -30 to +150 degrees C.
Key features
- Machined brass cage for large, heavily loaded positions
- Pure axial load in one direction
- Tolerates heat and marginal lubrication
- Separable washers for straightforward mounting
- Requires a separate bearing for radial location
- Operating range -30 to +150 degrees C
