Excellent material quality

The sintered bronze feels dense and durable. We use them in high-vibration environments, and they hold up perfectly. Shipping was fast too.

Reliable self-lubricating performance

These sleeves have been running in our conveyor system for three months without any maintenance. The self-lubricating property works exactly as described. Highly recommend for low-maintenance applications.

Good value for industrial use

We bought a batch for our assembly line. They perform well under moderate loads. One unit had a slightly rough edge, but nothing a quick deburr couldn't fix. Overall good value.

Perfect fit for our hydraulic pump

Ordered these bearings for a repair job on an old hydraulic pump. The dimensions were exact, and the oil-impregnated feature saved us time on initial lubrication. Very satisfied with the quality.

Great for retrofitting old equipment

Used these to replace worn-out bushings in some vintage machinery. The oil retention is excellent, and they run quietly. Will order again.

Standard industrial grade

Does exactly what it is supposed to do. No frills, just a solid bearing sleeve. The ID and OD measurements are accurate within tolerance.

5 FAQ

Q: Do you offer bulk discounts for orders over 100 units?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales department directly or request a quote through the product page for orders exceeding 50 units.

Q: What type of oil is impregnated in the bearing?

A: The bearings are impregnated with a standard SAE 30 non-detergent machine oil, which provides effective lubrication for general industrial purposes.

Q: Is this bearing suitable for high-speed applications?

A: This bearing is designed for low to moderate speed applications. For high-speed operations, we recommend consulting our engineering team to ensure it meets your specific load and heat dissipation requirements.

Q: Can I cut this sleeve to a shorter length?

A: Yes, the sintered bronze material can be cut to custom lengths using standard metalworking tools. However, please ensure the cut edges are deburred to prevent damage to the shaft.

Q: Are these bearings corrosion resistant?

A: While the bronze material offers good resistance to oxidation, they are not fully corrosion-proof against harsh chemicals or saltwater. For corrosive environments, additional protective measures may be needed.
