SKF bearings used in plastics machinery of the five types of bearings

Shanghai Institute Axis Trading Co., Ltd. today mainly to introduce SKF bearings used in plastics machinery bearing the five types of structures and characteristics. 
  First introduced the most widely used of a class: SKF bearings deep groove ball bearings 
  SKF bearings deep groove ball bearings are characterized by: each ring in the structure of deep groove ball bearings have a cross-section about the equatorial circumference of the ball three one-continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also bear certain axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearing can withstand both directions alternating axial load. Compared with the same size of other types of bearings, such bearings friction coefficient is small, extreme high speed, high precision, user selection of the preferred bearing type. 
  Second, SKF bearings tapered roller thrust structure, the performance characteristics of the bearings: 
  Since thrust tapered roller bearings in rolling element tapered roller in the structure due to the raceway bus rolling bus washer are intersect at the bearing axial line a point, so that the rolling surface can form pure rolling, limit speed higher than the thrust cylindrical roller bearings. Due to less production of thrust tapered roller bearings, the model of the plant has produced more non-standard dimensions, and less standard form factor series, the full production, which is currently no national dimensions of these bearings standard introduction. 
  Third, the structure of SKF bearings Axial angular contact ball bearings, the performance characteristics: 
  Axial angular contact ball bearing contact angle is generally 60 common thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindles, general double row cylindrical roller bearings are used together with, it can withstand two-way axial load, with high precision, good rigidity, low temperature, high speed, easy assembly and disassembly. 
  Fourth, double row tapered roller bearing structure, performance characteristics: 
  SKF row tapered roller bearing structure range is the maximum amount of 35,000 type, there is a double outer ring raceway and two inner ring, there is a barrier between the inner ring circle, changing the thickness of the spacer adjustable clearance. Such bearing radial load at the same time can withstand two-way axial load, and can limit the axial displacement of the housing within the bearing axial clearance range. 
  Fifth, SKF bearings tapered roller bearing structural features of: 
  SKF bearings tapered roller bearings are mainly used to bear radial load mainly radial and axial load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can withstand axial load in one direction, a direction to limit axial displacement of shaft or housing.
