Tolerances and clearances
General bearing specifications
- Tolerances: P6, P5
- Radial internal clearance: cylindrical bore, tapered bore
Bearing interfaces
- Seat tolerances for standard conditions
- Tolerances and resultant fit
Four-row cylindrical roller bearings are designed to accommodate very heavy radial loads in combination with medium to high speeds. The bearings are optimized for operating conditions typically found in long product mills, where they can provide increased performance and reduced total cost of ownership. Different design combinations of outer rings, inner rings, flange rings, etc. are available to fulfil different application demands. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
- Exceptional high radial load carrying capacity
- Low friction and long service life
- Low cross-sectional height
- Accommodate axial displacement in both directions
- Separable and interchangeable components
