GS81105 ISB ring

GS81105 ISB Thrust Washer (Housing Washer)

The GS81105 ISB is a high-precision raceway ring designed to operate in conjunction with 811 series cylindrical roller and cage thrust assemblies. As a GS-type washer, it is centered in the housing (housing washer). When combined with the appropriate roller assembly and a shaft washer (WS), it forms a complete thrust bearing characterized by exceptional axial stiffness. Manufactured from hardened bearing steel, this component ensures minimal friction and extreme resistance to point-load pressures.

Application

• CNC Machine Tools: Precise guidance for lead screws and spindles.
• Industrial Gearboxes: Transmitting massive axial forces within compact designs.
• Regulating Mechanisms: Systems requiring minimal play and high repeatability.
• Material Handling: Thrust rollers in heavy-duty conveyor systems.
• Hydraulic Presses: Bearing units in high-pressure heads.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: GS81105
• Part Type: Housing washer (outer centered)
• Compatibility: 81105 series cylindrical roller thrust bearings
• Material: High-quality chrome steel (hardened)

Note: Standard dimensions for the GS81105 are 25 mm (Bore) × 42 mm (OD) × 3 mm (Thickness).

Features and Benefits

• High Axial Load Capacity: Specifically engineered for cylindrical roller systems that carry much higher loads than ball-thrust alternatives.
• Perfect Raceway Geometry: The ground surface ensures perfectly flat contact with the rollers, eliminating vibrations.
• Modular Design: Allows for independent washer replacement without the need to purchase a full bearing assembly.
• Superior Hardness: Surface hardening prevents pitting and wear under intense axial pressure.
• ISB Quality Standards: Italian engineering guarantees full interchangeability with leading global brands.

Why Choose This Product

Selecting the GS81105 ISB thrust washer ensures the long-term stability of your bearing unit. In cylindrical thrust systems, the raceway's quality directly determines the service life of the rollers. This ISB washer offers an excellent performance-to-cost ratio, meeting the technical demands of modern machinery manufacturing and high-end industrial maintenance.
