Bimetal Bushings (JF / Steel-Backed Bronze Style)
Bimetal bushings (JF style) combine a steel backing with a bronze bearing lining. They are meant for conventionally lubricated joints — oil or grease — in machinery and equipment, not as a dry-running substitute. Clear naming helps purchasing match the drawing (bimetal vs PTFE or graphite-plugged).
When to use
- Oil- or grease-lubricated plain bearings
- Equipment joints with a defined lube path or grease point
- Steel-backed sleeves where bronze lining is specified
- Replacement of JF-style / steel-backed bronze positions
Not the first pick when: maintenance-free dry running is the goal — look at graphite-plugged or PTFE-lined instead.
Forms available
- Cylindrical (sleeve) bushings
- Flanged bushings
- JF-style reference sizes on request
Materials
Steel-backed bronze lining (leaded grades available where specified). Confirm alloy on RFQ.
Typical duty
Lubricated joints in construction and industrial equipment; hydraulic-related sliding positions specified as bimetal; OEM / MRO replacements for steel-backed bronze bushings.
Operating envelope (qualitative)
Requires oil or grease · load and speed per lining grade and lubrication quality. Limits from factory data on request.
