Product Features of 32004 X Bearings

  • Single row tapered roller bearings, inch sizes, designed to accommodate combined radial and axial loads and provide low friction in operation. The inner ring, including the rollers and cage, can be mounted separately from the outer ring.

  • These detachable and interchangeable parts facilitate installation, removal and maintenance. Rigid applications of bearings are achieved by mounting one single row tapered roller bearing on top of another and applying preload.

  • High radial and axial load carrying capacity

  • Accommodates axial loads in one direction

  • low friction and long service life

  • Separable and Interchangeable Components

Applications of 32004 X Bearings

  • Double row/single row tapered roller bearings are mainly used in gearboxes, lifting equipment, steel rolling mills and for mining machinery, such as pit boring machines.

  • In the front wheel hub of the car, the small size of double row tapered roller bearings are used

  • Four-row tapered roller bearings four-row tapered roller bearings used in large cold, hot rolling mills and other heavy machinery. Mainly used in heavy machinery.

Product classification of Tapered roller bearings

FAQ

  • Ball bearings are ideal for high-speed rotation, while roller bearings are more suited for high loads.
  • Because cylindrical roller bearings have separable inner and outer rings, they generally do not come with seals (open specification). As such, please apply seals or other protection around the equipment mounting.
  • EW Series bearings are small and utilize a pressed cage, making them suitable for standard operating conditions. ET Series bearings use a polyamide-resin cage suited for high temperatures. Finally, EM Series bearings have machined cages for use in harsh conditions such as gearboxes or vibrating machinery or in applications where the bearing must be quiet, such as in mid-to-large size motors.
