NSK 51112 Single Direction Thrust Ball Bearing 60x85x17

Overview

The NSK 51112 is a premium single direction thrust ball bearing designed to support axial loads acting in one direction only. It consists of a shaft washer, a housing washer and a precision ball-and-cage assembly that provides smooth rotation, low friction and excellent axial load capacity.

As part of NSK's 51100 Series, this bearing is manufactured to high precision standards and is widely used in industrial equipment where reliable axial load support is required. It is not intended to carry radial loads and should always be used in applications where axial forces are the primary operating load.

Industrial Applications

The NSK 51112 is commonly used in:

• Industrial gearboxes
• Electric motors
• Pumps
• Machine tools
• Agricultural machinery
• Conveyor systems
• Lifting equipment
• Hydraulic systems
• Heavy industrial machinery
• Power transmission equipment

Construction

The bearing features:

• Single direction thrust ball bearing design
• Shaft washer
• Housing washer
• Precision ball and cage assembly
• Pressed steel cage
• Open construction
• Flat housing seat design
• High axial load capacity

Its construction allows smooth rotation while efficiently transmitting axial loads from the rotating shaft to the stationary housing.

Material

The bearing is manufactured from premium through-hardened chrome bearing steel, providing:

• Excellent fatigue resistance
• High wear resistance
• Superior dimensional stability
• High running accuracy
• Long service life

The pressed steel cage ensures accurate ball guidance, low friction and reliable performance under heavy axial loads.
