Reliable industrial component

Ordered the 25mm length version. Precision is good and shipping was secure. Will order again for other machines.

Perfect for hydraulic press

These bushings fit perfectly in our hydraulic press setup. No oil needed which keeps things clean. Very satisfied with the durability.

Excellent self-lubricating performance

Running these in a high-duty cycle application. The graphite plugs are distributing well. No signs of wear after 3 months.

Good quality, tight fit

Material feels solid. Had to ream the hole slightly for our specific shaft tolerance but otherwise works great.

Solid value for money

Works as described. Took off one star because delivery took a bit longer than expected, but the product itself is top notch.

5 FAQ

Q: Is the 22mm ID exact or does it have tolerance?

A: There is a standard H7 tolerance. Please refer to the technical datasheet for specific machining allowances.

Q: What is the recommended shaft hardness?

A: We recommend a shaft hardness of HRC 45 or higher for optimal wear resistance.

Q: Do you offer bulk pricing for over 100 units?

A: Yes, please contact our sales team directly for volume discount quotes on large orders.

Q: Can these handle rotational speed of 1000 RPM?

A: No, these are designed for low-speed oscillating or sliding movements, typically under 0.5 m/s sliding speed.

Q: Can these be used in submerged water applications?

A: While water-resistant, prolonged submersion may affect lubrication efficiency. Best for dry or occasional exposure.
