Tristar DRJS-1216-8 Sleeve Bearing Rulon J 0.75in Id

Product Description

The TRISTAR DRJS-1216-8 is a sleeve bearing manufactured from Rulon J, a self-lubricating PTFE-based composite material suited for low-friction, maintenance-free bearing applications. It features a 0.75 inch inside diameter, a 1 inch outside diameter, and an overall length of 1 inch. This bearing type is used to support rotating shafts in motors, fans, pumps, and similar rotating equipment, providing a plain bearing surface without the need for rolling elements. It is a direct-replacement component typically installed by HVAC technicians, millwrights, and mechanical service professionals during motor rebuilds or equipment overhauls.

This sleeve bearing is suited for light-duty rotating shaft support in residential and commercial equipment, including fan motors, small pumps, and other motor-driven assemblies where a plain bearing is specified. The Rulon J material provides inherent lubricity, making it appropriate for applications where grease-packed or oil-impregnated bearings are undesirable or impractical. The compact 1 inch OAL makes it a fit for confined motor housings and tight bearing bores common in HVAC fan assemblies and similar equipment.

Key Features

• Rulon J self-lubricating composite material reduces maintenance requirements
• 0.75 inch inside diameter accommodates standard fractional motor shaft sizes
• 1 inch outside diameter for press-fit installation into standard bearing bores
• 1 inch overall length suits compact motor and fan housings
• Plain sleeve design eliminates rolling elements and associated failure points

Compatibility

Designed as an OEM-style replacement sleeve bearing for motors, fans, and rotating equipment specifying a 0.75 inch ID, 1 inch OD, 1 inch OAL plain bearing in Rulon J material.

Installation Notes

Sleeve bearings of this type are installed by HVAC technicians, motor repair technicians, and mechanical service professionals. Disconnect and lock out all power to the equipment before removing the worn bearing or disassembling the motor housing. Press-fit installation typically requires a bearing press or suitable arbor to seat the bearing squarely without distorting the bore. Follow the equipment manufacturer's service documentation for shaft clearance tolerances and housing fit specifications.
