Core Advantages:

Extreme Space Savings
The primary advantage of the AXK1226 2AS is its minimal axial cross-section (just 2 mm thick). It enables the design of more compact and lightweight products where axial space is at a premium, allowing engineers to overcome critical packaging challenges.
High Load Capacity in a Minimal Envelope
By utilizing numerous needle rollers, this bearing achieves an exceptional load-carrying capacity relative to its tiny size. It offers a far superior load density compared to a thrust ball bearing of similar dimensions.
Cost-Effective & Reliable Performance
It provides a robust and economical solution for axial location and load support in high-volume applications. The sealed design (2AS) ensures consistent performance and longer life by protecting the rolling elements.
Simplified Assembly & Handling
The integrated cage keeps the needle rollers perfectly aligned and pre-assembled, making installation quick, simple, and reliable, eliminating the risk of losing individual rollers.
High Rigidity & Precision
The line contact of the needle rollers provides high axial rigidity, ensuring precise axial positioning of components with minimal deflection under load.

Primary Application Scenarios

Automotive: Automatic transmission components (planetary gear sets), steering column assemblies, clutch release mechanisms, and actuator pivots.
Industrial Machinery: Compact gearboxes, rotary tables, indexing heads, and valve actuators.
Pumps & Compressors: As an axial bearing in small, high-speed pumps and compressor crankshafts.
Office Automation & Home Appliances: Paper feed mechanisms in printers/copiers, disc drives, and high-end power tools.
General Engineering: Any application requiring reliable axial support within a severely limited axial space.
