Tristar DR6S-0406-2 Sleeve Bearing Rulon 641 1/4 in Id

Product Description

The TRISTAR DR6S-0406-2 is a sleeve bearing manufactured from Rulon 641, a high-performance PTFE-based composite material known for low friction and self-lubricating properties. It features a 0.25-inch inside diameter, a 0.375-inch outside diameter, and an overall length of 0.25 inches. Sleeve bearings of this type provide a plain cylindrical surface that supports rotating or sliding shafts in light-load applications. This part is suited for OEM equipment repair and replacement work performed by mechanical technicians and maintenance professionals in HVAC, light industrial, and general equipment service environments.

This bearing is used in applications where a compact, self-lubricating plain bearing is required and where grease or oil lubrication is impractical or undesirable. Its small form factor makes it appropriate for fractional-horsepower motors, fan assemblies, small pumps, and similar rotating equipment found in residential and light commercial systems. Rulon 641 material performs well in dry-running conditions, making it a practical choice for sealed or maintenance-free assemblies where relubrication access is limited.

Key Features

• Rulon 641 PTFE-based composite construction provides self-lubricating, dry-running capability
• 0.25-inch inside diameter and 0.375-inch outside diameter for precise shaft and bore fitment
• Compact 0.25-inch overall length suits tight axial clearance requirements
• Sleeve bearing design supports radial loads on rotating or oscillating shafts
• No external lubrication required, reducing maintenance intervals in sealed assemblies

Compatibility

Designed as an OEM-style replacement sleeve bearing for fractional-horsepower motors, fan assemblies, and small rotating equipment requiring a 0.25-inch bore and 0.375-inch outer diameter plain bearing.

Installation Notes

Installation is typically performed by qualified mechanical or HVAC technicians. De-energize and lock out all electrical power to the equipment before disassembling any bearing housing or motor end bell. Press-fit installation should use a proper bearing press or driver sized to the outer diameter to avoid distorting the Rulon material. Do not use excessive force that could crush or deform the bearing wall, as this will reduce inside diameter clearance and restrict shaft movement.
