Product Details:

Four-row tapered roller bearings provide maximumcapacity in minimum space, combining the inherent high-load,radial/thrust capacity and direct/indirect mounting variables of taperedroller bearings.

Their main application is on the roll necks of rolling millequipment.All four-row bearings are supplied as pre-set matchedassemblies with all components identified to ensure correct installationsequence.

TQIT (Tapered Bore Four-Row Assembly)

Type TQIT bearings have a tapered bore that is matched and continuous through the inner races.This allows for an interference fit on the backup rolls of high-speed mills, where a loose inner race fit of a straight bore bearing could cause excessive neck wear.

Product Details:

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.

Product Details:

• The number of roller rows (one, two or four)
• The type of cage (with, without or special designs)
• Bearings with cage can accommodate heavy radial loads, rapid accelerations and high speeds.
• Full complement bearings (without cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
• SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage.
• The configuration of the inner and outer ring flanges (position and number of guide flanges)

• High load carrying capacity
• High stiffness
• Accommodate axial displacement: Except for bearings with flanges on both the inner and outer rings.
• Low friction: (Roller end / flange contact area)
  The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
• Long service life: The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
• Enhanced operational reliability: The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Separable and interchangeable: The separable components of SKF cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.

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.

• Exceptional high load carrying capacity: Because of their high number of rollers, four-row cylindrical roller bearings are suitable for very heavy radial loads.
• Low friction: (Roller end / flange contact area) The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction.
• Long service life: The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
• Enhanced operational reliability: The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Separable and interchangeable: The separable components of SKF four-row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
• High speed capability: The cage designs are suitable for high speeds, rapid accelerations and peak loads.
• Low cross-sectional height: The low cross-sectional height of four-row cylindrical roller bearings allows for relatively large roll neck diameters compared to the roll diameter.
