Smooth operation
No noise after installation. The oil impregnation is evident when machining. Great replacement parts for older machinery.

Good value bulk pack
Overall quality is solid for the price. One bushing was slightly tight on the bore, but nothing a little reaming couldn't fix.

Industrial quality
Using these in a low-speed conveyor application. They have been running smoothly for months without additional grease.

Excellent for robotics project
Fit perfectly on the shafts I ordered. The self-lubricating feature saves me time on maintenance. Highly recommend for hobbyist robotics.

Shipping was slow
Product is fine and meets specs, but the delivery took longer than expected. The bushings themselves work as described.
Q: Do I need to add additional grease during installation?
A: No additional grease is required as the bushings are oil-impregnated. However, a light coat of oil on the shaft during initial installation is beneficial.
Q: What is the maximum rotational speed recommended for these bushings?
A: Maximum speed depends on load and shaft hardness. Generally, we recommend staying below 150 ft/min surface speed for optimal life.
Q: Are these bushings certified for food processing equipment?
A: No, these standard bronze bushings are not FDA certified for direct food contact. Please consult our specialty catalog for food-grade options.
Q: Can these be cut to custom lengths if I order a longer sleeve?
A: Yes, they can be machined or cut to specific lengths. Please ensure you deburr the edges after cutting to maintain performance.
Q: What shaft hardness is recommended for pairing with these bushings?
A: We recommend a hardened steel shaft with a minimum hardness of 45 HRC to prevent premature wear on the shaft surface.
