Guide rollers mainly on steel Wuchang quality bearing steel (100Cr6) or stainless steel (X105CrMo17) manufacturing, heat treatment has good mechanical properties roller bearings, and Japan Tsubaki Nakashima (TSUBAKI) Precision Ball product performance further improved. DuPont (DUPONT) of plastic or high-Nissan strip (SPCC-SD) making cage bearings also provide a guarantee for reliable operation. Roller comes standard with Shell (SHELL) of high quality multi-purpose grease, nitrile rubber seals or high-Nissan strip (SPCC-SD) manufactured dust cover, to ensure that the products have been at work well lubricated and sealed against dust performance. In order to adapt to different products occasions spherical roller bearing pictures, but also can be customized in different filling oil prices aligning roller bearings, roller seals with different materials, such as using the German Krupp (KLUBER) of oil, High temperature fluorine rubber seals and so on. 1. Anti-magnetic bearings shielded bearings with low permeability non-magnetic material. The most commonly used anti-magnetic bearing material is beryllium (QBe2). It has good mechanical, physical, chemical overall performance. After quenching tempered high strength, hardness, elasticity and abrasion resistance Spherical roller bearings sales agents in the atmosphere, freshwater and seawater corrosion resistance is excellent. 2. Bearing vacuum bearing working in a vacuum environment is higher than 1.33Pa conditions, vacuum bearings, vacuum bearings are mainly used in space technology and X-ray tube, multi-radar control, power and other kinds of Frequency Agile magnetron vacuum apparatus. Multi-use vacuum bearing deep groove ball bearings and angular contact ball bearings. Manufacture rings and rolling bearing steel (GCr15) or stainless steel (9Cr18,9Cr18Mo). In recent years, high-pressure, high vacuum bearings are also manufactured using new bearing alloy G60.
