ISB LS3552 Thrust Washer (Raceway Washer)

The ISB LS3552 is a high-precision raceway washer manufactured from premium grade bearing steel. LS series washers are hardened and ground, specifically designed to serve as raceways for cylindrical rollers or needle rollers in thrust bearing assemblies. This series provides a cost-effective and space-saving solution for applications requiring high axial load capacity. The washer can function as either a shaft or a housing washer.

Application

• Machine Tools: Providing a stable rotation plane for axial components.
• Industrial Gearboxes: Managing axial forces within compact housing designs.
• Material Handling: Bearing support for rollers and joints under axial pressure.
• Construction Equipment: Components of hydraulic steering and drive systems.
• Mechanical Engineering: Used where adjacent components are not hardened and require an additional raceway.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: LS3552
• Part Type: Raceway washer
• Material: High-carbon chrome steel (hardened).
• Compatibility: AXK needle thrust assemblies and 811 series cylindrical roller assemblies.

Note: Standard dimensions for the LS3552 are 35 mm (Bore) × 52 mm (OD) × 3.5 mm (Thickness).

Features and Benefits

• High Axial Stiffness: Despite its thin profile, the washer effectively supports high point loads from the rollers.
• Precision Ground Finish: Ensures minimal rolling resistance and eliminates vibration in the bearing unit.
• Versatility: Can be used as a replacement for both WS (shaft) and GS (housing) washers.
• Fatigue Resistance: Advanced heat treatment prevents pitting and abrasive wear under heavy loads.
• Space Efficiency: Perfect for designs where mounting width is strictly limited.

Why Choose This Product

Choosing the ISB LS3552 thrust washer ensures the correct operational geometry for your thrust bearing. In cylindrical and needle systems, the quality and hardness of the raceway determine the actual service life of the rollers. This ISB product delivers European manufacturing standards, protecting adjacent machine parts from premature wear and ensuring smooth, stable axial movement.
