Backing bearings ( Back-up bearings )

FV backing bearings are available in many designs and variants. The main assortment is based on double 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 specially developed for cold rolling mills of the cluster type, but can also be used for other applications, such as straightening or bending machines. These bearings have a particularly thick-walled outer ring and can be mounted on stationary support shafts to form backup or straightening rolls. We shows the arrangement of the backing bearings on the eight support shafts of a 20-roll mill.

  • Size range: I.D. 50mm~210mm
  • Applications: Sendzimir cold strip mill Sendzimir planetary mill

Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.

The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life.

Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.

Special variants

In addition to the bearings presented in this section, FV supplies cylindrical roller bearings for special application requirements. This assortment includes:

  • Bearings with Solid Oil

  • INSOCOAT bearings

  • Hybrid bearings

  • NoWear coated bearings

  • Super-precision bearings

  • Backing bearings

  • Indexing roller units

  • Cylindrical roller bearings and bearing units for railway applications ( contact FV )

Features and benefits:

  • High load carrying capacity

  • High stiffness

  • Accommodate axial displacement

  • Low friction

  • Long service life

  • Enhanced operational reliability

  • Separable and interchangeable
