Tristar DRS-0204-3 Sleeve Bearing Rulon Lr 1/8 in Id

Product Description

The TRISTAR DRS-0204-3 is a sleeve bearing manufactured from Rulon LR, a self-lubricating PTFE-based composite material suited for low-friction, maintenance-free applications. With an inside diameter of 0.125 inches, an outside diameter of 0.25 inches, and an overall length of 0.375 inches, this compact bearing is designed to support rotating or sliding shafts in light-duty assemblies. Its Rulon LR construction provides inherent lubricity, eliminating the need for external grease or oil in most service conditions. HVAC technicians, equipment repair pros, and mechanical service trades use bearings of this type as direct replacements in small motors, fan assemblies, and similar rotating equipment.

This sleeve bearing is suited for residential and light commercial applications where a small-format, self-lubricating plain bearing is required. Typical install scenarios include replacement of worn shaft bushings in small fractional-horsepower motors, blower assemblies, and other rotating components found in HVAC equipment, appliances, and general mechanical systems. Its compact dimensions make it appropriate for confined shaft-support locations where rolling-element bearings are impractical.

Key Features

• Rulon LR material provides self-lubrication for maintenance-free operation
• Inside diameter of 0.125 inches fits standard 1/8-inch shafts
• Outside diameter of 0.25 inches for press-fit installation in standard housing bores
• Overall length of 0.375 inches suits compact, space-constrained assemblies
• Lightweight construction at 0.1 pounds per unit

Compatibility

Designed as an OEM-style replacement sleeve bearing for small rotating assemblies requiring a 0.125-inch inside diameter, 0.25-inch outside diameter, Rulon LR plain bearing.

Installation Notes

Installation is typically performed by a qualified mechanical or HVAC technician. Power down and de-energize the equipment completely before removing the worn bearing and installing the replacement. Press-fit installation should be performed with appropriate hand tools or an arbor press to avoid distorting the bearing bore. Verify shaft and housing dimensions before installation to ensure correct fit and alignment.
