Durable under load
Using these in a high-vibration environment. They have held up better than the previous polymer bushings we used.

Perfect for conveyor systems
Installed these on our packaging line. The self-lubricating feature saves us maintenance time. Fit was precise.

Reliable industrial component
Ordered the MPTZ-20 size. Dimensions matched the engineering drawings perfectly. Fast shipping too.

Good quality, tight fit
Material feels robust. Had to press them in firmly but once seated they perform well. No squeaking after weeks of use.

Excellent dry running performance
We needed something that could run without oil mist. These graphite bushings are exactly what we needed. Highly recommend.
Q: Are these suitable for underwater applications?
A: While corrosion resistant, they are designed for dry or ambient conditions. Submerged use may require specific sealing.
Q: Do these require any initial lubrication before installation?
A: No, the graphite plugs provide immediate lubrication upon movement. You can install them dry.
Q: What is the tolerance on the inner diameter?
A: Standard H7 tolerance is applied to the inner diameter for metric shafts.
Q: Is there a break-in period for these bushings?
A: A short run-in period is recommended to allow the graphite to distribute evenly on the shaft surface.
Q: Can I order a custom flange size?
A: Yes, we offer customization for bulk orders. Please contact our sales team for details.
