Great value
For the price, you cannot beat the quality. The flange is sturdy and provides good support. Just make sure to measure your shaft diameter carefully before ordering.

Smooth operation
After installing this guide bushing, the linear motion of my 3D printer gantry is much smoother. No more wobble. The stepped design is very convenient.

Exactly as described
Needed a replacement for an old worn-out liner in my lathe setup. This T-shaped sleeve fits perfectly and the hardened surface seems very durable.

Perfect fit for my CNC project
The tolerances on this sleeve are excellent. It slid onto my 25mm shaft with just the right amount of friction. The shouldered design made alignment very easy during installation.

Professional grade component
We use these in our prototype assembly line. The consistency between the different ID sizes we ordered (15mm and 20mm) is impressive. Highly recommended for industrial use.

Good quality steel
Solid construction and the grinding marks are very fine. I deducted one star only because the shipping took a bit longer than expected, but the product itself is great.
Q: Is this sleeve compatible with stainless steel shafts?
A: Yes, this hardened steel sleeve is designed to work with standard stainless steel or chrome-plated linear shafts of the corresponding inner diameter.
Q: What is the exact outer diameter for the 25mm ID version?
A: The outer diameter varies slightly based on the specific wall thickness required for load bearing, but for the 25mm ID model, the OD is typically 40mm. Please check the detailed dimension chart in the product images.
Q: Is the flange thick enough to be bolted down directly?
A: Yes, the T-shaped flange is designed with sufficient thickness and surface area to allow for direct bolting or mounting into a housing bracket without deformation under normal loads.
Q: Does this come with lubrication pre-applied?
A: The sleeve comes with a light protective oil coating to prevent rust during storage. We recommend cleaning it and applying your preferred linear motion grease or oil before final installation.
Q: Can this be used in high-temperature environments?
A: This sleeve is rated for standard industrial operating temperatures up to 150°C. For applications exceeding this, please contact us for specialized high-temp alloys.
