Tristar DR6S-0406-3 Sleeve Bearing Rulon 641

Product Description

The TRISTAR DR6S-0406-3 is a sleeve bearing manufactured from Rulon 641, a self-lubricating polymer composite widely used in low-friction, maintenance-free bearing applications. With an inside diameter of 0.25 inches, an outside diameter of 0.375 inches, and an overall length of 0.375 inches, this compact bearing is engineered for precision fit in rotating or oscillating shaft assemblies. It is installed by maintenance technicians and mechanical service professionals working on equipment where reducing metal-to-metal contact and minimizing lubrication maintenance are the primary objectives.

This sleeve bearing is suited for light-duty industrial and commercial equipment applications where a small-diameter, self-lubricating bushing is required. Typical installations include motors, fans, small appliances, and mechanical assemblies that run continuous or intermittent duty cycles. Its compact form factor makes it a practical replacement in space-constrained housings where rolling-element bearings are not practical or cost-effective.

Key Features

• Rulon 641 material provides self-lubricating, low-friction performance without requiring grease or oil
• Inside diameter of 0.25 inches for precise shaft fit
• Outside diameter of 0.375 inches for standard housing press-fit installation
• Overall length of 0.375 inches suits compact, space-constrained assemblies
• Lightweight construction at approximately 0.1 pounds
• Sold individually - minimum order quantity of 1

Compatibility

Designed as a replacement sleeve bearing for light-duty rotating and oscillating shaft assemblies requiring a 0.25 inch ID, 0.375 inch OD, self-lubricating polymer bushing.

Installation Notes

Sleeve bearings of this type are typically pressed into a machined housing bore using an arbor press or bearing insertion tool - do not hammer directly on the bearing face. Ensure the shaft and housing are clean and free of burrs before installation. Power down and de-energize all equipment before servicing any bearing assembly. Rulon 641 bearings do not require post-installation lubrication under normal operating conditions.
