Good quality, precise dimensions
Dimensions matched the spec sheet perfectly. Fit was snug. Only giving 4 stars because shipping took a bit longer than expected.

Self lubricating feature is a lifesaver
Reduces maintenance time significantly. No need to grease frequently. Great replacement for our old copper bushings.

Perfect for high load applications
Installed these on our hydraulic press. The graphite impregnation works well without extra oil. Very satisfied with the durability.
Q: Does this bearing require additional grease or oil?
A: No, the JDB-8090 features embedded graphite plugs that provide self-lubrication during operation.
Q: What is the recommended shaft tolerance?
A: We recommend a shaft tolerance of f7 or g6 for optimal sliding performance with this bushing.
Q: What is the lead time for bulk orders?
A: Standard orders ship within 3-5 business days. Bulk orders over 100 units may require 10-15 business days.
Q: Can you customize the flange diameter?
A: Custom sizes are available upon request. Please contact our sales team for non-standard dimensions.
Q: Is this suitable for underwater applications?
A: Yes, the bronze material is corrosion resistant, but prolonged submersion may affect performance depending on water chemistry.
