Withstands heat well
Used these in a high-temperature environment near a furnace feed. They performed consistently without seizing. The self-lubrication holds up well under thermal stress.

Perfect for automation lines
We replaced our standard oiled bushings with these MPBZ13 units. The self-lubricating feature has significantly reduced maintenance downtime on our conveyor system. Fit was precise.

High quality alloy
The copper alloy feels robust and durable. We have been running these for three months continuously without any signs of wear. Great value for the price point.

No maintenance needed
Excellent product for hard-to-reach areas where oiling is difficult. The graphite plugs work smoothly even under high load conditions. Highly recommended for industrial use.
Q: Do you offer bulk discounts for orders over 100 units?
A: Yes, volume pricing is available. Please contact our sales department directly through the inquiry form for a customized quote.
Q: What is the percentage of graphite in the alloy?
A: The exact formulation is proprietary, but the graphite plugs are strategically placed to ensure optimal lubrication coverage during rotation.
Q: What is the lead time for the 30mm size?
A: The 30mm variant is typically in stock and ships within 1-3 business days. Custom sizes may require additional production time.
Q: Can these bushings be used in submerged water applications?
A: These are designed for dry or semi-dry industrial environments. Submerged use is not recommended as it may affect the graphite lubrication efficiency.
Q: What is the tolerance range for the inner diameter?
A: Standard tolerance is H7 for the inner diameter and g6 for the outer diameter. Please consult the technical datasheet for specific size variations.
