Backing bearings

  • SKF backing bearings are available in a variety of designs and types. The main classification is based on double-row or three-row cylindrical roller bearings.
  • Single-row needle roller bearing and double-row tapered roller bearing designs are also available.
  • Backing bearings have been developed specifically for use in clustered cold rolling mills, but can also be used in other applications, such as straightening or bending machines.
  • These bearings have a particularly thick outer ring and can be mounted on a fixed support shaft to form a support or straightening roll. The diagram shows the arrangement of backing bearings on eight support shafts in a 20-roll mill.

Products of Backing bearings

Features and Benefits

  • High load capacity
  • Low friction
    Optimized internal geometry reduces friction and heat generated by the bearing.
  • Long service life Logarithmic
    The logarithmic roller profile reduces edge stress at the roller/raceway contact under all load conditions. In addition, the logarithmic outer ring OD profile reduces edge loading during operation, contributing to longer service life.
  • Improved operational reliability
    The surface finish of the roller and raceway contact surfaces supports the formation of a hydrodynamic lubrication film.
  • Effective lubrication
    Most SKF backing bearings have lubrication holes, and many have one or more annular grooves in the inner ring for lubrication through the support shaft.

Applications

  • Support bearing, is made of steel plate as the substrate, sintered spherical bronze powder in the middle, rolled PTFE and mixture on the surface.
  • It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. It can reduce the cost, reduce the volume of machinery, avoid the phenomenon of shaft gnawing and reduce noise and other advantages.
  • The product has been widely used in the sliding parts of various machinery, such as:
  • printing machines, textile machines, tobacco machinery, automobiles, motorcycles and agricultural and forestry machinery, manufacturing plants, machinery repair stores, etc.

FAQ

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers.

  1. The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running.
  2. Learn more about bearing damage and bearing failure – and how to prevent it.

Sure, free samples are available for stock products if you can pay for the shipping cost.

We have regular stock for standard bearings that can be shipped right after your payment. It will take 15-60 days for new production order,which depends on your order quantity.
