PRODUCT DETAILS

Product introduction:

1, ordinary linear optical shaft (sf) : Because the ordinary linear optical shaft is in contact with the linear bearing point opposite, the surface hardness of the ordinary linear optical shaft is very high, so the material and heat treatment method are very important. Material: suj2 (equivalent) national standard gcr15. Hardness: hrc602 hardening layer depth: 0.8-3mm Surface roughness: ra0.10m-ra0.35m straightness: 70um/1000mm below shaft diameter tolerance g6

2, chrome-plated linear optical shaft (sfc: Chrome-plated linear optical shaft is plated with a layer of hard chromium on the basis of the ordinary linear optical shaft, which can be applied to the environment that is easy to rust or bad environment. Material: suj2 (equivalent) national standard gcr15. Hardness: hrc602 hardening layer depth: 0.8-3mm Surface roughness: ra0.10m-ra0.35m straightness: 70um/1000mm below chromium plating layer thickness: 3m-5m. Shaft diameter tolerance g6

3, Chrome plated linear flexible shaft (rsfc) : Chrome plated linear flexible shaft because of its thick chrome plating layer can be directly used in precision piston rod and some in the self-lubricating bearing. Because its hardness is relatively moderate, it has been applied in many fields. Material: 45# or 40cr or 2cr13 Hardness: hb220-260 Hardening layer depth: 0.8-3mm straightness: 0.15mm/1000mm below chromium plating layer thickness: 0.02-0.05mm

4, stainless steel linear spool: stainless steel linear spool has high corrosion resistance, high strength and wear resistance to maintain its efficient operating performance. Therefore, it can be used in situations prone to oxidation, such as water, chemicals, steam, sea water, etc. Material: sus404c, sus304 Hardness: hrc602 Hardening layer depth: 0.8-3mm Surface roughness: ra0.10m-ra0.35m straightness: 70um/1000mm below chromium plating layer thickness: 3m-5m. Shaft diameter tolerance g6

5, chrome plated hollow shaft: Chrome plated hollow shaft due to the characteristics of its hollow structure, the hollow shaft greatly reduces the weight and simplifies the structure, and its interior is suitable for inserting measuring wires, compressed air, adding lubricating oil, or for robot arms
