Structure and performance characteristics of NACHI bearing

    NACHI Axial angular contact ball bearing contact angle is generally used for the 60 °angular contact thrust ball bearings are generally two-way thrust angular contact ball bearings, mainly for precision machine tool spindles, usually with double row cylindrical roller bearings used in conjunction with, affordable two-way shaft to the load, with high precision, rigidity, low temperature, high speed, easy assembly and disassembly, etc.

  NACHI deep groove ball bearings in the structure of each ring has a cross-section of both the equatorial circumference of the ball is about one-third of long continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also can withstand a certain degree of axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearings, can withstand both directions alternating axial load. With the same size compared to other types of bearings, such bearings coefficient of friction, extreme high speed, high precision, user selection is the preferred type of bearing. Deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used class of imported bearings.

  NACHI thrust tapered roller bearings tapered roller thrust bearings as the rolling of tapered roller, rolling in the structure of the bus and ring bus raceway bearings are converging on a point of the axis line, so the surface can be formed of pure rolling rolling speed limit higher than the thrust cylindrical roller bearings. Features: Thrust tapered roller bearings can withstand a one-way axial load. Thrust tapered roller bearing type code 90000 type. 4, bearing the import of two-row tapered roller bearing structure, performance characteristics double row tapered roller bearings range, the maximum amount of 35,000 type, has a double outer and two inner ring raceways, between the two inner there is a spacer, to change the thickness adjustable spacer clearance. Such bearing radial load can withstand two-way axial load at the same time, in the axial clearance in the bearing shaft and housing within the limits of the axial displacement. Tapered roller bearing structural features. Tapered roller bearing type code is 30000, tapered roller bearings for the separation of bearings. Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with the angular contact ball bearings, load capacity, low speed limits. Tapered roller bearings can withstand axial load in one direction, the shaft or housing to limit the axial displacement in one direction.
