Precision Instrument Guide Sleeve

Test instruments need very precise guides. We have been making precision guide parts since 2011. We supplied high-accuracy sleeves for Sany Heavy Industry. Their test equipment has very strict requirements. We met them. This Precision Instrument Guide Sleeve is used on optical test instruments and medical precision equipment. It is also used on measuring instruments and micro drive units. These sleeves must guide with very high accuracy. They must have very low friction. We use tin bronze and stainless steel 304/316L. We also use bearing steel GCr15 and engineering wear alloys. You get a sleeve that guides with precision.

The inner diameter tolerance is IT4 to IT6 grade. This Precision Instrument Guide Sleeve has a roundness and cylindricity under 0.003 mm. The radial runout is under 0.005 mm. The inner hole surface roughness is Ra≤0.2 to 0.4μm. The fit gap is 0.005 to 0.02 mm. The working temperature is -30℃ to 120℃. The surface gets polishing and hard chrome plating. We also do passivation and phosphate coating. You get a sleeve that moves with almost no friction.

We do not just sell a metal sleeve. We give you precision that walks with you. This Precision Instrument Guide Sleeve is used on optical instruments and medical devices. It is also used on measuring equipment and precision micro drives. Do you need it for a test instrument? Yes. Do you need it for a medical device or optical sensor? Yes. The materials are tin bronze, 304/316L stainless steel, GCr15 bearing steel, and engineering wear alloys. You get a guide sleeve with the highest accuracy. Since 2011, we have been making precision parts for the most sensitive jobs.
