Spherical roller bearings: rolling body is convex or concave spherical roller tune heart to heart bearing. Convex spherical roller bearings, spherical outer ring has a raceway; there are concave roller bearings, the inner ring has a spherical raceway. Thrust roller bearings: rolling body is a roller thrust bearing. Thrust cylindrical roller bearings: rolling body is a cylindrical roller thrust bearing. Thrust tapered roller bearings: rolling body is tapered roller thrust bearing. Thrust needle roller bearings: rolling body is thrust needle roller bearing. IKO bearings IKO bearings features introduced is a registered trademark of Thomson (NIPPON THOMPSON CO., LTD) is a technology and technological development-oriented industrial parts manufacturer, to produce needle roller bearings and linear guide bearings known professional Manufacturers around the world enjoy a high reputation, needle roller bearings produced in Japan is the oldest, most complete, highest level of professional manufacturers. Its products are widely used in machine tools and various other industries. Stainless steel bearing timber of mechanical and physical properties: martensitic chromium stainless steel with the increase of C content, the strength of steel cheapest boards bearing, hardness up to RC60 above board bearing the best quality, wear-resistant steel good, but poor toughness. When containing Mo, V, increase the strength of steel. Containing a small amount when Ni, steel strong - with good toughness. Such steel brittle transition temperature, magnetic, low density, shock resistance, modulus of elasticity is slightly lower than carbon steel. Martensitic chromium-nickel stainless steel with high strength (ós not less than 9800MPa) and high hardness (RC of not less than 36), high strength / weight ratio. Material in stainless steel in the bearing: SUS304, SUS316, SUS316L: austenitic stainless steel in the bearing inner and outer rings, ball, cage, rivet circuit boards bearing, bearing seat, the top wire, the dust cover of the best board bearing manufacturers , seals skeleton. Martensitic stainless steel bearings in the cage, rivet, bearing seat, the top wire, shield, seal skeleton. SUS440C, SUS440B: martensitic stainless steel bearings in the inner and outer rings, balls. The following table lists commonly used stainless steel grades comparison table: austenitic type Type GB (China) ASTM (USA) JIS (Japan) DIN (Germany) uses austenitic Austenite1Cr17Ni7301SUS301X12CrNi177 heat, corrosion resistance, a variety of purposes.
