INA AXK 0821-TV 8x21x2 Needle Roller and Cage Thrust Assembly

Precision Needle Roller Cage Assembly for Compact Axial Bearing Applications

The INA AXK 0821-TV 8x21x2 is a premium needle roller and cage thrust assembly manufactured by Schaeffler. Designed for applications requiring high axial load capacity and minimal installation height, the AXK series consists of precision needle rollers retained in a lightweight cage. Unlike a complete thrust bearing, this assembly must be used together with suitable thrust bearing washers to create a complete axial bearing arrangement. Its compact dimensions, excellent running accuracy and low friction make it an ideal solution for industrial machinery, gearboxes, pumps and precision mechanical equipment.

Application in Industrial Systems

The INA AXK 0821-TV is widely used in:

• Industrial gearboxes
• Electric motors
• Hydraulic pumps
• Oil pumps
• CNC machine tools
• Industrial automation equipment
• Agricultural machinery
• Conveyor systems
• Compact transmission units
• Precision mechanical assemblies

The assembly is specifically designed for applications where extremely compact axial bearing arrangements are required without compromising load capacity.

Construction and Design

The INA AXK series is engineered for maximum axial performance in confined installation spaces.

Key design features include:

• Needle roller and cage thrust assembly
• Precision ground needle rollers
• High-strength polyamide cage (TV design)
• Compact axial construction
• Optimized roller guidance
• Uniform load distribution
• Low friction operation
• Designed for use with thrust bearing washers

The assembly operates together with thrust bearing washers such as AS0821 and LS0821, forming a complete thrust bearing system.

Material Properties

The assembly is manufactured using premium bearing materials that provide:

• High wear resistance
• Excellent fatigue strength
• Precision roller guidance
• Stable dimensional accuracy
• Low rolling resistance
• Long service life
• Reliable operation under high axial loads
