Perfect for hydraulic repair
Used the MPTZ40 model for a hydraulic cylinder repair. The fit was precise and the graphite plugs seem to be holding up well under constant pressure. Highly recommend for industrial maintenance.

Good quality, slight delay
The bearings themselves are excellent quality brass. Machining tolerances are spot on. Only giving 4 stars because shipping took a bit longer than expected, but the product is solid.

Excellent wear resistance
Replaced standard bushings with these graphite-embedded ones. The wear resistance is noticeably better, reducing our downtime for maintenance. Will purchase again.

Meets all specifications
Verified the hardness and dimensions against our engineering specs. Everything matches the datasheet. Great self-lubricating performance in dry conditions.

Durable and reliable
We ordered a batch for our molding machines. No squeaking or excessive wear after three months of continuous operation. The flanged design makes installation very straightforward.
Q: Do you offer custom flange sizes?
A: Standard sizes are listed, but we do offer custom machining services for bulk orders. Please reach out to our sales team with your specific requirements.
Q: Can these be used in high-temperature environments?
A: They are rated for operating temperatures between -10°C and +150°C. For temperatures exceeding this range, please contact us for alternative material options.
Q: How should these be installed?
A: These are press-fit bushings. Ensure the housing bore is clean and use a proper arbor press to install evenly without damaging the flange.
Q: Are these compatible with standard hydraulic oil?
A: Yes, these brass sleeve bearings are compatible with standard hydraulic oils and greases, though they are designed to operate self-lubricated via the graphite plugs.
Q: What is the tolerance for the inner diameter?
A: The inner diameter typically follows H7 tolerance standards. Please refer to the specific size chart for the MPTZ model you select for exact measurements.
