Solid product
Exactly as described in the specs. Shipping was fast and packaging protected the sleeves well. Would buy again.

Great for high heat applications
Used these in our kiln conveyor system. The solid lubricant holds up well where grease would burn off. Very satisfied with the durability.

No grease needed
Saves us a lot of maintenance time. We don't have to schedule regular lubrication anymore. The graphite plugs work exactly as described.

Good fit but tight tolerance
Quality is excellent, but the fit was very tight. Required slight reaming during installation. Once installed, performance is solid.

Durable and reliable
Been running these in heavy machinery for 6 months now. No signs of wear yet. Highly recommend for industrial use.
Q: What is the maximum RPM recommended?
A: Maximum RPM depends on the load, but generally these sleeves perform well up to 500 RPM under standard conditions.
Q: Do you offer bulk pricing for large orders?
A: Yes, please contact our sales department directly for volume discounts on bulk purchases.
Q: Is this material corrosion resistant?
A: Yes, the high-strength brass base offers good resistance to corrosion in most industrial environments.
Q: Can I use additional oil with these sleeves?
A: It is not necessary as the graphite provides solid lubrication, but compatible oils will not damage the material if required for specific conditions.
Q: What shaft tolerance is recommended?
A: We recommend an H7/f7 fit for optimal performance and longevity of the bearing sleeve.
