Tristar DRJS-1620-8 Sleeve Bearing Rulon J 1in Id

Product Description

The TRISTAR DRJS-1620-8 is a Rulon J sleeve bearing designed for low-friction, self-lubricating rotary and linear shaft support applications. With a 1 inch inside diameter, a 1-1/4 inch outside diameter, and a 1 inch overall length, this bearing provides a compact, press-fit solution for equipment requiring smooth, maintenance-reduced operation. Rulon J is a PTFE-based composite material known for low friction, chemical resistance, and the ability to run dry without additional lubrication. This bearing is installed by maintenance technicians and mechanical contractors in machinery, HVAC equipment, and light industrial assemblies where conventional lubricated metal bearings are impractical or undesirable.

This sleeve bearing is suited for residential and commercial applications where shaft loads are moderate and operational temperatures fall within the performance range of Rulon J material. Typical installations include fan shaft supports, pump housings, and rotating equipment assemblies that benefit from a dry-running, corrosion-resistant bearing surface. Its compact geometry makes it a practical drop-in fit for confined bearing bores requiring a standard 1 inch shaft clearance.

Key Features

• Rulon J PTFE-composite construction allows dry, self-lubricating operation without grease or oil
• 1 inch inside diameter accommodates standard 1 inch shafts
• 1-1/4 inch outside diameter for press-fit installation into standard bearing bores
• 1 inch overall length provides a compact footprint for space-constrained assemblies
• Chemical-resistant material suitable for environments where lubricants would contaminate or degrade
• Lightweight construction at 0.1 pounds reduces added load on rotating assemblies

Compatibility

Designed as a replacement sleeve bearing for rotating equipment requiring a 1 inch ID, 1-1/4 inch OD, 1 inch OAL Rulon J bearing. Verify bore diameter, shaft diameter, and overall length against the existing installation before ordering.

Installation Notes

Installation is typically performed by qualified maintenance technicians or mechanical contractors. Power down and de-energize all equipment before removing the worn bearing. Press-fit bearings should be seated using an appropriate bearing press or driver to avoid cocking or cracking the bore housing. Do not hammer directly on the bearing face, as Rulon J composite material can crack under uneven impact loads.
