Overview
Nachi 51103 G Thrust bearing
Axial Deep Groove Ball Bearing, single direction with polyamide cage
The Nachi 51103 G is a single-direction thrust ball bearing measuring 17 mm shaft washer bore, 30 mm housing washer outside diameter and 9 mm assembly height, with a glass-fibre reinforced polyamide cage. The moulded cage weighs less than pressed steel and runs more quietly, which suits the lighter, faster thrust positions found in machine tool and appliance work. The bearing carries axial load in one direction only and takes no radial load, so a separate bearing must locate the shaft. Washers separate for mounting, rated -20 to +120 degrees C.
Key features
- Glass-fibre reinforced polyamide cage
- Pure axial load in one direction
- Lighter and quieter than a steel-caged equivalent
- Separable washers for straightforward mounting
- Requires a separate bearing for radial location
- Operating range -20 to +120 degrees C
