Tristar DRF-0305-2 Flanged Sleeve Bearing Rulon Lr

Product Description

The TRISTAR DRF-0305-2 is a flanged sleeve bearing manufactured from Rulon LR, a self-lubricating composite material suited for low-friction, maintenance-free applications. It features a 3/16 inch bore, a 5/16 inch outside diameter, and an overall length of 1/4 inch. The flanged design includes a 7/16 inch flange outside diameter and a 1/16 inch flange thickness, providing axial location and load distribution in the housing bore. This bearing supports plain bore operation and is rated for a maximum pressure-velocity (PV) value of 10,000 psi. It is installed by mechanical and maintenance technicians across industrial, HVAC, and equipment repair applications where oil-free operation is required.

This bearing is suited for use in small rotating or oscillating shaft assemblies where continuous lubrication is not practical. Typical installations include fan blade pivot points, small motor shaft supports, linkage assemblies, and light-duty rotating mechanisms in HVAC equipment, appliances, and industrial machinery. The Rulon LR material provides inherent lubricity, eliminating the need for grease or oil in service, which reduces maintenance intervals and contamination risk in sensitive environments.

Key Features

• Self-lubricating Rulon LR composite material - no grease or oil required in service
• Flanged design with 7/16 inch flange OD provides axial positioning and housing retention
• Plain bore accepts 3/16 inch shaft diameter
• Rated to 10,000 psi maximum pressure-velocity (PV) value
• Compact overall length of 1/4 inch fits space-constrained assemblies
• Single-piece construction - sold individually, MOQ of 1

Compatibility

Designed as an OEM-style replacement flanged sleeve bearing for small shaft assemblies requiring a 3/16 inch bore, 5/16 inch outside diameter, and 1/4 inch overall length in Rulon LR self-lubricating material.

Installation Notes

Installation is typically performed by mechanical technicians or equipment repair specialists. De-energize and lock out all power to the equipment before removing the worn bearing. Press-fit installation is standard for flanged sleeve bearings of this type - use a properly sized arbor or press to avoid distorting the bore or flange. Verify shaft diameter and housing bore tolerances before installation to ensure correct fit and rated performance.
