Four row cylindrical roller bearings

Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high. Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads. FV four-row cylindrical roller bearings are available in several designs: 1. with a cylindrical or tapered bore. 2.open or sealed.

  • Size range: 145 mm to 1040 mm Bore
  • Applications: Back-up rolls Work rolls Cement crushing Cement roller press

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
