Perfect Fit for Conveyor System
Replaced worn bushings on my conveyor system with these HRB-78 units. The dimensions were exact and installation was straightforward. Highly recommend for industrial maintenance.

Excellent Durability
Running under heavy load and high temperature. These bushings are holding up well without excessive wear. Great value for manufacturer direct pricing.

Good Quality Bronze
Solid bronze construction as described. The machining finish is smooth. Only giving 4 stars because delivery took a bit longer than expected, but the product itself is great.

Great Price Point
Buying direct from the manufacturer saved us quite a bit compared to local suppliers. Quality matches the more expensive brands we have used in the past.
