Frequently Asked Questions
Q: What are the material specifications of the BR 6597-025 Oilite bearing?
A: The BR 6597-025 is a sintered bronze bearing manufactured to ASTM B438 standards. It contains 9.5 to 10.5% tin content, 0.6 to 1.0% graphite content, and maintains a minimum 19% porosity by volume to retain oil for self-lubrication. Yield strength in compression is 11,000 psi minimum with 1% elongation in 1 inch.
Q: What equipment is the BR 6597-025 bearing verified for?
A: The BR 6597-025 is OEM verified for Barrett lift equipment, specifically pallet jacks with model designation WRPN 60/80 or WRPN60/80. Verify your equipment model matches before ordering.
Q: How does the oil impregnation in the BR 6597-025 maintain bearing performance?
A: The 19% minimum porosity in the sintered bronze structure is saturated with oil during manufacturing. As the bearing operates, friction heat causes the oil to migrate to bearing surfaces, providing continuous self-lubrication without external oil application.
Q: Can the BR 6597-025 bearing be used in high-temperature or wet environments?
A: The BR 6597-025 is designed for standard indoor pallet jack applications. Extreme temperature fluctuations or prolonged moisture exposure can cause oil depletion and bearing failure. Verify your operating environment matches manufacturer specifications.
Q: What is the expected service life of the BR 6597-025 bearing?
A: Under normal operating conditions, the BR 6597-025 provides 3 to 7 years of service. Increased noise, mast drag, or difficulty moving the lift indicates the bearing is worn and requires replacement.
