Rollers

Rollers are the components bored with loads in bearing operation. They are also the weakest component whose quality will directly affect the bearing’s performance like rotating speed, vibration level and flexibility. It’s also the key element for service life of bearings. Based on different categories, rollers can be divided into spherical, tapered, cylindrical rollers. According to different precision level, they are divided into grade I, II and III.

ZWA Bearing Recommendations
  • Tapered Roller Thrust Bearing

    Tapered Roller Thrust Bearing

    This bearing can form a compact assembling in axial direction. The bearing is stiff and can bear heave axial loads but is insensitive to radial loads.
  • Deep Groove Ball Bearings

    Deep Groove Ball Bearings

    Deep groove ball bearings, also known as DGBB bearing, are the typical rolling bearings which have the most widely application.
    Basic deep groove ball bearings of different sizes are made up of one inner ring, one outer ring, one cage and a group of balls. It can bear both radial and axial load capacity. Therefore, it can also be divided into axial deep groove ball bearing and radial deep groove ball bearing.
  • Angular Contact Ball Bearings

    Angular Contact Ball Bearings

    Angular contact ball bearing, also known as acbb bearing, is a kind of inseparable bearing, the side shoulders of inner ring and outer ring are uneven. In order to increase the load capacity, one of the side shoulder will be lower than the other. This kind of bearings has raceways both on inner ring and outer ring.
