roller bearings

Taper roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes taper roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. Taper roller bearings are generally separable, xxxxx the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).Taper roller bearings are produced by in many designs and sizes to match their many uses. These can be grouped as follows � single row taper roller bearings � double row taper roller bearings � four-row taper roller bearings Cylindrical Roller Bearings Features : 1) Separable 2) As the roller linearly comes into contact with inner ring and outer ring with less coefficient of friction, these bearings have very good capacity of radial load, and are suitable for electric motors, automobiles, transmission shafts and gear shafts 3) Double-row cylindrical roller bearings are greatly used for the spindles of machine tools 4) Models available: NU, NG, NUP, N, NF, NH, NNU, NIV Spherical Roller Bearings formed outer ring raceway can make self-alignment. Their rolling elements linearly come into contact with the raceways of inner ring and outer ring. The can take great radial load. Features : 1) Spherical roller bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in out ring, the two inner ring raceways are included at an angle to the bearing axial 2) The bearings have good self-aligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft misaligning in mounting, and their permissible aligning angle is 1 to 2.5 degree 3) This type of bearings has heavy load carrying capacity and anti-impact ability.
