Chrome Steel Deep Groove Ball Bearings 606 ZZ Miniature Deep Groove Bearing
Description,
1. Bearings on the market are generally divided into two materials, high-quality standard bearing steel and standard high-carbon steel.
2. Standard bearing steel is a nationally recognized bearing material application standard (Gcr2005). The hardness standard range is HDC60-62 degrees. Bearing steel has high and uniform hardness, good wear resistance, and high elastic limit. It is used as a bearing. Good material. Steel mills have strict requirements on the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides, which are strict steel types required in all steel production.
3. High-carbon steel material, with a certain proportion of carbon components, after quenching (that is, steel heat treatment), although the hardness is in the range of 50-55 degrees, less than standard bearing steel, but the material is more tough than standard bearing steel, and important The cost is effectively reduced, and the resulting bearing is more cost-effective. It is widely used in areas where Mohs hardness is not high.

Deep groove ball bearing sizes, Features,
1. Bearing 6210 can also be used: leisure food processing equipment, plastic sheet equipment, boiling dryers, food packaging machinery, pharmaceutical packaging machinery, electric pumps, fruit and vegetable processing equipment, plastic drawing machines, dairy machinery, biscuit machinery, plastic knitting machines, hot air stoves, frozen food processing equipment, food sterilization equipment, plastic machine accessories Fresh-keeping refrigerating equipment, gearbox, rice noodles, mechanical compression molding machine, horizontal dryer.
2. Deep groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.
3. The bearing ring grooves are circulararcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).
4. Deep Groove baal bearings can sustain radial,axial ,or composite loads and beacuse of simple design,this bearing type can be produced to provide both high-running accuracy and high-speed operation.
