Linear Bearing Shaft

The linear Bearing Shaft is a product that has a guiding function of a sliding bearing and enables linear motion. The requirements for these linear motion systems are: simple design, best execution capability, low maintenance cost, strict selection of durable materials, high frequency heat treatment, accurate outer diameter dimensions, roundness, and straightness. And surface treatment, etc.

Classify

1. Ordinary linear Shaft (sf): Since the ordinary linear optical axis is in point contact with the linear bearing point, the surface hardness of the ordinary linear optical axis is very high, so the material and the heat treatment method are important. Material: suj2 (equivalent) national standard gcr15. Hardness: hrc60±2; hardened layer depth: 0.8-3mm; surface roughness: ra0.10m-ra0.35m; straightness: 70um/1000mm or less; shaft outer diameter tolerance g6

2, chrome-plated linear shaft (sfc): chrome-plated linear optical axis is based on the ordinary linear optical axis coated with a layer of hard chrome, also known as bearing rod, can be applied to the environment of easy rust or bad environment. It is widely used in industrial robots, the moving part of automatic slip system devices.Suj2 (equivalent) national standard gcr15. Hardness: hrc60±2; hardened layer depth: 0.8-3mm; surface roughness: ra0.10m-ra0.35m

3, chrome linear flexible shaft (rsfc): chrome linear soft shaft due to its thick chrome layer can be directly used for precision piston rods and some self-lubricating bearings. Because of its moderate hardness, it has been applied in many fields. Material: 45# or 40cr or 2cr13; hardness: hb220-260; hardened layer depth: 0.8-3mm; straightness: 0.15mm/1000mm or less; chrome plating thickness: 0.02-0.05mm

4, stainless steel linear shaft: stainless steel linear shaft has high corrosion resistance, high strength and wear resistance to maintain its efficient running performance. Therefore, it can be applied to places where oxidation is likely to occur, such as water, chemicals, steam, sea water, and the like. Material: sus404c, sus304 hardness: hrc60±2; hardened layer depth: 0.8-3mm; surface roughness: ra0.10m-ra0.35m straightness

5, chrome-plated hollow shaft: chrome-plated hollow shaft. Due to its hollow structure, the hollow shaft greatly reduces the weight and simplifies the structure. The interior is suitable for penetrating measuring wires, compressing air, adding lubricating oil, or Used for robotic arms.

Application:

Linear Shaft are widely used in many linear motion systems such as cylinder rods, automatic precision printers, automatic cutting machines and industrial robots.
