Tapered Roller Bearings- Single Row / Double Row / Four Row

Image of Tapered Roller Bearing
Tapered roller bearings can manage both thrust and radial loads on rotating shafts and in housings. It consists of single, double, and four-row configurations. Customized geometries and engineered surfaces can be applied to these bearings to further enhance performance in demanding applications. The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surface and roller axes if projected would all meet at a common point on the main axis of the bearing. Tapered roller bearings consist of four interdependent components: the cone, the cup, the tapered rollers, and the cage.

Types Of Tapered Roller Bearings

  • Single row taper roller bearings have low friction and are often used in pairs to support axial thrust loads on both sides.
  • The advantage of a single row tapered roller bearing is its high surface area contact.
  • Single row taper roller bearings are commonly used in can-wheel bearings.

  • A double row tapered roller bearing has two separate sets of tapered raceways and rollers.
  • Double row tapered roller bearings are highly durable and offer excellent stiffness.
  • A double row tapered roller bearing is typically used in gearboxes, hoisting equipment, rolling mills, and mining machinery.

  • The basic design of four row tapered roller bearing bearings is based on the observation that cones roll over each other without slipping and are capable of bearing radial and axial forces. 
  • In general, a four row tapered roller bearing is mounted on a roll neck with a clearance fit.
  • The four-row tapered roller bearing is commonly used for low to medium speeds in rolling mills.
