High-capacity cylindrical roller bearings
SKF high-capacity cylindrical roller bearings have the high load carrying capacity of full complement bearings and the high speed capability of bearings with cage. They are designed for applications such as industrial gearboxes, wind turbine gearboxes and mining equipment.
High load carrying capacity
The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers (fig. 1, fig. 2, fig. 3, fig. 4).
The increased number of rollers increases radial stiffness.
High speed capability
The cage designs are suitable for high speeds, rapid accelerations and peak loads.
Long service life
The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:
smearing damage resistance
- running-in properties and reducing friction
- performance under poor lubrication conditions
- chemical resistance (from agressive oil additives)
- smearing damage resistance
