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.
Q: Do you sell these with a 25mm bore size?
A: Yes, please check the variant options at the top of the product page for 25 mm and 30 mm bore sizes.
Q: Can these sleeves be welded onto a shaft?
A: Welding is not recommended as it may alter the heat treatment and hardness of the steel. Press fitting is the preferred method.
Q: Is lubrication required during installation?
A: Yes, we recommend applying standard industrial grease to the bore and outer surface during installation to prevent galling.
Q: What is the standard lead time for shipping?
A: Orders placed before 2 PM EST typically ship within 24 hours via standard ground shipping.
Q: Is this suitable for high friction applications?
A: Yes, these sleeves are made from wear-resistant steel designed to handle moderate to high friction environments.
