Plastics Machinery in five categories SKF bearing structural performance and characteristics
Plastics Machinery in five categories SKF bearing structural performance and structural characteristics 1. Thrust tapered roller, roller bearing performance characteristics: Since thrust tapered roller bearings in rolling element tapered roller, the structure and the rolling bus washer raceway bus intersect at the bearing axis are online at some point, so that the rolling surface can form pure rolling, limit speed higher than the thrust cylindrical roller bearings. NSK Bearings Thrust tapered roller bearings can withstand axial load unidirectional. Thrust tapered roller bearing type code is 90000. 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. 2. Axial angular contact ball bearing structure, 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 spindle, general and double row cylindrical roller bearings are used in conjunction with, can withstand two-way axial load, with high precision, good rigidity, low temperature, high speed, easy assembly and disassembly, etc.. 3. The double row tapered roller bearing structure, performance characteristics: FAG bearings double 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, the inner ring between the two there is a spacer, a change in 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. 4. The tapered roller bearing structural features: tapered roller bearing type code 30000, tapered roller bearings for the separation of bearings. Under normal circumstances, especially in the GB / T307.1-94 "Rolling bearings tolerance" within the cone are involved in the size range between roller bearing outer ring and inner components are interchangeable hundred percent can be used. The outer ring raceway angle and an outer diameter same size and shape has been standardized prescribed for. Not allowed to change the design and manufacturing time. To cause between the tapered roller bearing outer ring and inner components can be interchanged in common worldwide. NTN 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. 5. 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 one-third of the 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. INA deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used class of bearings.
