Combined Cylindrical Taper Roller Bearings

Combined cylindrical roller/tapered roller bearings, also referred to as "Kombi rolling mill bearings". They comprise two single row cylindrical roller bearings and one double row tapered roller bearing, and support radial loads and axial loads separately. The outer cylindrical roller bearings have high load carrying capacity and are only subjected to radial loads. The cylindrical rollers are guided between two integral flanges on the inner ring, whilst the low flange on the inboard side of the outer ring serves to hold the bearing together until it is mounted. The tapered roller bearing with steep contact angle positioned between the two cylindrical roller bearings has two rows of rollers in a face-to-face arrangement and takes the axial load.

Four row cylindrical roller bearings

FV "Kombi rolling mill bearings" are employed as work roll bearings on Four-high stands of both hot and cold rolling mills and of cold sheet rolling mills. Increased demands with respect to the quality and accuracy of the rolled product as well as further developments in the production process for sheet steel involving the introduction of contra-bending and axial displacement of the rolls have meant that work roll bearing loads have been considerably increased. This means that the four-row tapered roller bearings normally used as work roll bearings can often not meet the requisite life demands because of the much heavier radial and axial loads applied. Compared with standard four-row tapered roller bearings, this Kombi rolling mill bearings design can withstand greater rolling forces.

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

  • Bearings with Solid Oil

  • INSOCOAT bearings

  • Hybrid bearings

  • NoWear coated bearings

  • High load carrying capacity

  • High stiffness

  • Accommodate axial displacement

  • Low friction

  • Long service life

  • Enhanced operational reliability

  • Separable and interchangeable
