Perfect fit for our hydraulic press

These bushings replaced our old oil-lubricated ones perfectly. The graphite inserts provide excellent lubrication even under heavy loads. No more messy oil leaks.

Excellent for dirty environments

Since they don't require external oil, dust and debris don't stick to the mechanism anymore. This has significantly reduced our maintenance downtime.

Good value for money

Solid construction. They handle the lateral load well thanks to the round flange. Delivery was fast and packaging protected the items well.

Solved our overheating issue

Previous bushings would overheat due to friction. These graphite-embedded units run cool and smooth. Installation was straightforward.

Durable and reliable

We have been running these in a high-vibration environment for three months now with zero wear visible. The flange design makes installation very secure.

5 FAQ

Q: Can I use this for a shaft with a diameter slightly larger than 16mm?

A: The inner diameter is precision-machined to 16mm. For proper fit and longevity, we recommend using a shaft with an h6 or h7 tolerance class close to 16mm.

Q: What is the maximum operating temperature for this copper alloy?

A: This specific copper-graphite composite can safely operate in temperatures ranging from -40°C up to +250°C without losing structural integrity.

Q: Does this bushing require regular greasing or oiling?

A: No, the MPTZ-16-20-25 features embedded solid graphite plugs that provide self-lubrication throughout its lifespan, making it completely oil-free.

Q: Is the flange removable if I don't need it?

A: No, the round flange is cast as an integral part of the bushing to provide axial location and support. It cannot be removed without damaging the unit.

Q: Are these resistant to corrosion in outdoor applications?

A: Yes, the copper alloy base offers good natural corrosion resistance. However, for harsh chemical environments, additional protective coatings may be advisable.
