Excellent for high-load applications

Installed these in our conveyor system. The graphite embedding works perfectly without additional oil.

5 FAQ

Q: Are these suitable for outdoor use?

A: Yes, the bronze alloy is corrosion resistant, but we recommend protection from direct saltwater exposure.

Q: What is the tolerance for the inner diameter?

A: Standard tolerance is H7 for the inner diameter. Please check the specific datasheet for your size.

Q: What is the lead time for MPTZ-25?

A: Most sizes are in stock for fast delivery. Bulk orders may take 3-5 business days.

Q: Can these handle oscillating motion?

A: Yes, graphite-embedded bronze is ideal for oscillating or slow-rotating movements.

Q: Do I need to grease these during installation?

A: No, these are self-lubricating. However, a light film of oil on the outer diameter helps with press fitting.
