Bunting Bearing BJ4S162012 Ptfe Sleeve Bearing

Product Description

The BUNTING BEARING BJ4S162012 is a PTFE sleeve bearing designed for plain bore shaft applications in light to moderate industrial equipment. Constructed from polytetrafluoroethylene, this self-lubricating bearing requires no added grease or oil during normal service. It measures 1 inch inside diameter, 1-1/4 inches outside diameter, and 1-1/2 inches overall length. The PTFE material provides a low-friction running surface and handles a maximum pressure-velocity rating of 30,000 psi, making it well suited for steady-load rotating or oscillating shaft configurations where maintenance access is limited.

This sleeve bearing fits residential and light commercial mechanical equipment, conveyor systems, small motors, pumps, and general industrial machinery where a compact plain bore bearing is required. The 1-inch bore accommodates standard shaft diameters common in fractional and integral horsepower drive assemblies. Maintenance technicians and millwrights typically install this bearing during scheduled rebuilds or when replacing worn or damaged bronze or sintered metal bushings with a lower-maintenance PTFE alternative.

Key Features

• PTFE construction provides self-lubrication - no external lubricant required during normal operation
• Maximum pressure-velocity rating of 30,000 psi for steady radial load applications
• Plain bore design accepts standard 1-inch diameter shafts
• 1-1/4 inch outside diameter for straightforward housing press-fit installation
• Compact 1-1/2 inch overall length suits space-constrained assemblies
• Bearing number DRS162012 for cross-reference identification

Compatibility

Designed as an OEM-style replacement sleeve bearing for plain bore applications requiring a 1-inch ID, 1-1/4-inch OD, and 1-1/2-inch overall length PTFE bushing.

Installation Notes

Installation is typically performed by a maintenance technician or millwright. Power down and lock out the equipment before removing the shaft assembly. Press the bearing into the housing bore using an appropriately sized arbor press - avoid driving the bearing in at an angle to prevent deformation of the PTFE liner. Do not apply grease or oil to the bearing bore, as the PTFE surface is designed to run dry.
