NSK 51148 Thrust Ball Bearing 240 × 300 × 45 mm

Overview

NSK 51148 Thrust Ball Bearing is designed specifically to support axial load with a simple, low-friction structure. It is suitable for vertical shafts, rotary tables, jacks, and low- to medium-speed equipment where axial load control is more important than radial load capacity.

The bearing consists of shaft washer, housing washer, and ball-and-cage assembly. Single-direction types support axial load in one direction, while double-direction types support axial load in both directions; they are not intended for radial loading.

Selection guidance

Verify axial load direction, speed, washer type, mounting face squareness, and whether any radial load is present.
