Perfect Fit for Machinery

Exactly what I needed for my lathe project. The 304 steel is high quality and the dimensions were accurate.

Check Measurements

Product is fine but make sure to measure your shaft carefully before ordering. OD was slightly larger than my housing.

Good Material Quality

Steel is high quality and polished well, but shipping took a bit longer than expected.

Very Durable

No signs of wear after months of use in a high vibration environment. Highly recommend.

5 FAQ

Q: What is the tolerance level on the ID?

A: We maintain standard industrial H7 tolerance for inner diameters unless specified otherwise.

Q: Can I order mixed sizes in one batch?

A: Please contact customer service directly to arrange mixed SKU orders for bulk purchases.

Q: Are these threaded inside?

A: No, these are smooth isolation sleeves. Threaded options are available in a different listing.
