Good value for bulk orders
Solid product for the price. We use them in multiple fixture setups. One sleeve had a very minor cosmetic mark, but it did not affect functionality. Would order again.

Perfect fit for our gauge fixtures
We ordered these round bushings for our new automotive inspection line. The tolerances are spot on, and the surface finish is excellent. No issues with insertion or wear after a week of heavy use.

High quality standard parts
Exactly as described. The hardened steel holds up well against repeated insertion of inspection pins. Delivery was fast and packaging prevented any damage during transit.

Standard reliable component
Nothing fancy, just a high-quality bushing that does its job. The threading on the optional threaded version is clean and precise. Slightly higher price than generic brands but worth it for consistency.

Fast shipping and great durability
Needed these urgently for a production audit. They arrived two days early. The black oxide coating seems durable and provides good corrosion resistance in our shop environment.

Reliable for precision work
Our quality control team verified the dimensions against our CAD models, and everything matched perfectly. These sleeves are now our standard for all new fixture designs.
Q: Are these bushings compatible with metric and imperial pins?
A: Our standard stock focuses on metric sizes per ISO standards, but we can manufacture custom imperial sizes upon request. Please contact our sales team with your specific dimensions.
Q: Do you provide material certification with the shipment?
A: Absolutely. Every batch comes with a Mill Test Certificate (MTC) detailing the chemical composition and hardness test results to ensure compliance with industry standards.
Q: What is the lead time for a bulk order of 500 units?
A: For items marked 'In Stock', we can ship up to 200 units immediately. Orders between 200-500 units typically require 3-5 business days for final quality inspection and packaging.
Q: Can these be used in high-temperature environments?
A: Yes, the hardened alloy steel retains its structural integrity up to 300°C. However, please note that the black oxide coating may discolor above 200°C, though functionality remains unaffected.
Q: Is the inner diameter adjustable or fixed?
A: These are fixed-size precision bushings designed for specific pin diameters to ensure accurate inspection. They are not adjustable. Please select the exact size required for your application.
