Good but heavy

Quality is fine but the weight made installation a bit tricky for my specific application. Make sure your setup can handle the mass.

Excellent for shaft repair

Fit perfectly on my lathe project. The tolerance was spot on and the material feels very durable. Highly recommend for machinery maintenance.

Solid construction

Heavy duty steel sleeves. They are slightly heavier than expected but that indicates good quality. Shipping was fast.

Precise dimensions

Measured exactly as stated in the description. No issues with installation using a standard press fit. Will buy again.

Great value

Bought for industrial use in our workshop. The black oxide coating provides nice corrosion resistance. Very satisfied with the purchase.

A: Yes, please check the variant options at the top of the product page for 25 mm and 30 mm bore sizes.
