Tristar DR6T-0410-2 Thrust Bearing Washer Rulon 641

Product Description

The TRISTAR DR6T-0410-2 is a thrust bearing washer designed to manage axial loads in rotating assemblies. Made from Rulon 641, a self-lubricating PTFE-based composite material, this washer provides low-friction performance without requiring additional lubrication. It measures 0.25 inches inner diameter, 0.625 inches outer diameter, and 0.0625 inches thick. The compact, lightweight design - weighing approximately 0.1 pounds - makes it suitable for precision mechanical applications where space and weight are constraints. Machinists, mechanical contractors, and equipment service technicians install this type of bearing washer during maintenance or rebuild of rotating shaft assemblies.

This thrust bearing washer is suited for use in light-duty rotating or oscillating shaft applications where axial load support is needed. The Rulon 641 material performs well in environments where conventional lubricated bearings are impractical, including food-adjacent equipment, pumps, and similar assemblies. Its washer-style form factor allows for straightforward insertion between mating surfaces during assembly or replacement service.

Key Features

Compatibility

Designed as an OEM-style replacement thrust bearing washer for rotating shaft assemblies requiring a 0.25 inches ID, 0.625 inches OD, 0.0625 inches thick Rulon 641 washer.

Installation Notes

Installation is performed by qualified mechanical technicians during equipment disassembly and rebuild. De-energize and fully lock out equipment before removing or replacing bearing components. Ensure mating shaft and housing surfaces are clean and free of burrs before seating the washer. No lubrication is required for Rulon 641 material - do not apply grease, as it may attract contaminants and reduce bearing life.
