Bunting Bearing BJ4S101406 Ptfe Sleeve Bearing

Product Description

The BUNTING BEARING BJ4S101406 is a PTFE sleeve bearing designed for light-load rotary and sliding applications where self-lubrication is required. Constructed from polytetrafluoroethylene, this bearing provides a low-friction interface between rotating shaft and housing without the need for external lubricant. The 0.625-inch inside diameter accepts standard fractional shafting, while the 0.875-inch outside diameter fits common bore housings. Overall length of 0.75 inches suits compact assemblies where axial space is limited. Installed by millwrights, HVAC technicians, and maintenance mechanics in motors, fans, pumps, and light industrial equipment.

This sleeve bearing is suited for residential and light commercial applications including fan motors, small pump assemblies, and appliance drives where a press-fit plain bearing is specified. The PTFE material makes it appropriate for environments where oil or grease lubrication is not practical, including food-adjacent equipment, clean-room environments, and applications subject to wash-down. Bearing number DRS101406 cross-references this part within the Bunting Bearing catalog for replacement sourcing.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance mechanic. Power down and lock out the equipment before removing the worn bearing. PTFE sleeve bearings are generally press-fit into the housing bore; use an arbor press and a properly sized installation driver to avoid distorting the bearing wall. Do not hammer directly on the bearing face.
