PEER's Tapered Roller Bearings: Features & Engineered Design

PEER Bearing designs and manufactures award-winning precision bearing solutions to industry leaders around the globe. Tapered roller bearings (TRB) are an important product category at PEER, featuring low maintenance requirements and long service life.

Our Tapered Roller Bearings 
PEER’s tapered roller bearings consist of tapered cylindrical rolling elements housed in an outer raceway known as a cup and an inner raceway referred to as a cone (see assembly diagram below).

The operating principle behind the design of the TRBs relies on the relative motion between cones in contact, which creates a true rolling motion if their axes converge to a single point. Hence there will be no sliding friction between the surfaces in contact, such as between the inner surface of the cup, the inner/outer edges of the rolling elements and outer surfaces of the cone.

This design creates a large contact area between the rolling and housing elements, making them capable of bearing large loads. Since the rolling elements are tapered, they can carry both axial and radial loads. The greater the angle of the taper, the greater the contact angle, increasing the thrust load that the TRB can carry.

PEER is involved in all aspects of bearing fabrication from design to production to ensure that all parts of our tapered roller bearings are able to withstand the loads they encounter.

Engineering Our Tapered Roller Bearings
Tapered roller bearings typically come in one of three styles:

Double-row assembly

No matter the type, the cup and cone of tapered roller bearings are separable pieces. This allows for optimal preload and clearance between cup and cone.

Our TRBs also offer customizable advantages. For example, a TRB can be designed to retain grease in the bearings cavities in order to extend the service life of the bearings. We have also developed technology that allows our tapered roller bearings to accommodate considerable misalignment without any reduction in service life. When determining appropriate customizations for an application, PEER's engineers consider:

  • Calculation of radial and axial forces on the bearings
  • The spread of the bearings and directions they will face
  • Operating speeds
  • Radial loads
  • Expected life of individual bearings

PEER's tapered roller bearings have advanced features such as raceway surface finishes, controlled roller to rib contact, optimized rollers, and undercut designs that improve bearing performance and service life.
