Spherical roller bearing with seat is a kind of bearing unit which combines rolling bearing and bearing seat. Most of the outer spherical bearings are made of spherical outer diameter and installed with imported bearing housings with spherical inner holes, which have good versatility and interchangeability. [Strong bearing capacity, corrosion resistance and durability] Built-in steel balls, with good bearing capacity, sturdy and durable High-quality zinc alloy materialSmooth surface, comfortable hand feeling, convenient and easy to install [Sealed, dustproof and durable] With sealing rings on both sides, it can strictly prevent the intrusion of dirt and has strong sealing performance High speed and low noiseThe bearing has high precision, strong toughness, corrosion resistance and longer service life Bearing housing material Zinc alloy 1. Relatively large. 2. Good casting performance, it can cast precision parts with complex shapes and thin walls, and the surface of the cast parts is smooth. 3. Surface treatment is available: electroplating, spraying, painting, polishing, grinding, etc. 4. It does not absorb iron during melting and die casting, does not corrode the casting, and does not stick to the mold. 5. Has good mechanical properties and wear resistance at room temperature. 6. Low melting point, melting 385, easy to cast. Bearing materialBearing steel Product specification KFL08 diamond seat inner diameter 8mm 6pcs
