AS2542 ISB washer

ISB AS2542 Thrust Washer (Thin Raceway)

The ISB AS2542 is a high-precision thrust washer manufactured from hardened spring-bearing steel. The AS series rings are characterized by their extreme thinness, enabling the construction of very flat bearing arrangements. They are ground and polished on both sides, allowing them to work directly with AXK needle roller thrust assemblies. They are an ideal solution when machine housing components are not hardened and mounting space is critically limited.

Application

• Planetary and Automatic Gearboxes: Compact bearing support for gears under axial pressure.
• Precision Machine Tools: Providing a stable rotation plane in adjustment mechanisms.
• Piston Pumps: Operating under high axial pressure in demanding environments.
• Automotive: Clutches, starters, and other components requiring thin thrust bearings.
• Industrial Automation: Precise axial guidance in actuators and drives.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: AS2542
• Part Type: Thin-walled thrust washer
• Material: Hardened chrome steel (high surface hardness).
• Compatibility: AXK2542 needle thrust assemblies.

Note: Standard dimensions for the AS2542 are 25 mm (Bore) × 42 mm (OD) × 1 mm (Thickness).

Features and Benefits

• Extremely Slim Profile: A thickness of only 1 mm allows for significant space saving in machine design.
• Double-sided Precision: Both surfaces are finished with equal precision, simplifying the installation process.
• High Hardness: Hardened steel prevents pitting and wear caused by needle roller pressure.
• Cost-Effective Protection: Protects expensive machine housing parts from direct wear by the rolling elements.
• ISB Quality: European manufacturing standards ensure perfect parallelism between surfaces.

Why Choose This Product

The ISB AS2542 thrust washer is the simplest and most effective way to provide a professional raceway for needle thrust bearings. It eliminates the risk of rapid wear on non-hardened machine parts. By choosing ISB, you invest in a component with high operational quality that minimizes friction and heat generation, directly contributing to the overall reliability of your equipment.
