- Low friction - 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
- The separable components of SKF® 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
- Min. Order Qty: 1

DESCRIPTION
SKF® 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.
