ZVL 51101 Single Direction Thrust Ball Bearing 12x26x9

Overview

The ZVL 51101 is a premium single direction thrust ball bearing designed to support axial loads acting in one direction only. It consists of a shaft washer, housing washer and a precision ball-and-cage assembly, ensuring smooth operation, low friction and excellent axial load capacity.

Manufactured by ZVL Slovakia, the bearing complies with ISO standards and belongs to the internationally standardized 51100 Series. It is specifically designed for applications where accurate axial shaft positioning is required while radial loads are supported by separate bearings. Thrust ball bearings of this type are not suitable for radial loading.

Industrial Applications

The ZVL 51101 is widely used in:

• Industrial gearboxes
• Machine tools
• Hydraulic equipment
• Presses
• Spindle assemblies
• Lifting equipment
• Agricultural machinery
• Industrial production machinery
• Mechanical power transmission systems
• General engineering applications

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 seating surfaces
• High axial load capacity

The bearing is designed exclusively for axial loads acting in one direction and must not be subjected to radial loads.

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 and reliable operation under demanding axial loading conditions.
