Stainless steel bearing timber of mechanical and physical properties: martensitic chromium stainless steel with the increase of C content, the strength of steel, the hardness of injection molding machines bearing up to RC60 above, steel wear resistance, 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. Materials used in stainless steel bearings in: SUS304, SUS316, SUS316L: austenitic stainless steel bearings in the inner and outer ring, balls, cage, rivets, bearings sit bearings, the top wire, shield, seal skeleton. Martensitic stainless steel bearing retainer rivets linear bearings, 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. Class 8: Thrust ball bearings Thurst ball bearings -51000 unidirectional, bidirectional 52000 Applications: used in automobiles, machine tools and other industries. Features: Thrust ball bearings from the seat, shaft ring and ball cage assembly in three parts. And the axis of said shaft washer, and the shell with said seat. Acceptance of sub-way thrust ball bearings and thrust ball bearings. Thrust ball bearings can withstand axial load, two-way thrust ball bearings can withstand axial load. Thrust ball bearing linear bearing guide, ring and the shaft with them. Appear before the installation of the spherical bearing race, with aligning properties, can reduce installation errors. Thrust ball bearings can bear radial load, lower speed limit Class 8: Thrust ball bearings Thurst ball bearings -51000 unidirectional, bidirectional 52000 Applications: used in automobiles, machine tools and other industries.
