Boundary Lubrication Thrust Washers

Definition

Boundary lubrication thrust gasket is a mechanical part that works with the principle of boundary lubrication, and relies on an extremely thin lubrication film adsorbed on the surface to reduce friction and bear axial load. It is often installed in the shafting to prevent axial movement and ensure the stable operation of the equipment.

Core advantage:
Intelligent lubrication system: Multi-layer composite structure (steel back + porous bronze layer +PTFE composite) for long-term lubrication
Ultra-high load capacity: static load up to 200MPa, dynamic load 80MPa, PV value up to 5.5N/mm² m/s
Extreme conditions adaptation: -40℃~220℃ wide temperature range stable operation
Surface engineering technology: Laser microtexture design improves lubricant retention

Technical parameters:
Base material: high strength alloy steel
Friction layer: POM composite layer
Thickness range: 0.5-10mm (tolerance ±0.01mm)
Friction coefficient: μ=0.07-0.12 (boundary lubrication condition)
Compliance with standard: ISO 3547/DIN 988

Typical applications:
Engineering machinery: axial positioning of excavator slewing support
Wind power equipment: gearbox thrust bearing
Industrial transmission: heavy gear reducer axial support
Special environment: dust, humidity and other conditions that are difficult to maintain

Special note:
Free sample testing (standard models only)
Laser identification can be customized for bulk orders
