Bearing features
- 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). - High stiffness
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)
- corrosion resistance
- smearing damage resistance
