Great Spacer Solution

Used these as spacer sleeves in an assembly line. They are durable and the surface finish is smooth.

Solid Product

Good value for the price. Came with a light oil coating which is standard for steel protection. Cleaned up easily.

Perfect Fit for Conveyor Repair

Ordered the 60mm ID sleeve for a conveyor belt repair. The hardness is exactly as described and the fit was precise. Highly recommend for industrial use.

Good Quality, Slow Shipping

The steel sleeve itself is excellent quality and machined well. Only giving 4 stars because shipping took a bit longer than expected.
