Bunting Bost-Bronz Powdered Metal (SAE 841)
Bunting Bost-Bronz Powdered Metal (SAE 841) is part of the Bunting Bearings range of self-lubricating powdered-metal plain bearings (oil-impregnated sintered bronze and iron-copper) and solid cast-bronze plain bearings, plus self-lubricating nylon liner bearings. Direct functional equivalent of Bushingo BP25 (oil-impregnated sintered bronze). Same self-lubricating principle and impregnation-oil concept; BP25 sleeve, flange and thrust forms quote one-for-one against Bost-Bronz / SAE 841 part families. Closer to BP25 than any competitor grade.

Key features
- Self-lubricating and maintenance-free — porous structure acts as an internal oil reservoir
- Oil drawn to the interface under motion and load, then re-absorbed at rest
- Quiet, clean running with no external greasing required
- Well suited to low-to-moderate speed rotary, oscillating and linear motion
- Cost-effective in volume and available in a very wide standard size table
Typical applications
- Fractional-horsepower electric motors
- Pumps and small gear drives
- Household and office appliances
- Power tools
- Automotive ancillaries and general machinery
