The main dimensions of the tapered roller bearings comply with DIN ISO 355 and DIN 720. Dimensional and running tolerances match tolerance course PN acc. to DIN 620. These tolerance classes are standard and are well suited for most applications.

The bearings are separable. This means the bearing parts could be fitted independently of each different. The bearings are provided without seals. They could be lubricated with grease or oil from the side.

The rollers are processed to create Tapered Roller Bearing china pore-like micro indents in the surface of the steel (rolling contact surface and roller head). This microstructure helps keep an oil film that’s perfect for tapered roller bearing applications. Improved oil film retention substantially inhibits surface damage, reaching more than eight circumstances higher durability and equal or greater seizure resistance in comparison to conventional products.
Superior lubricant oil accumulation and retention (simpler to form oil film) in the roller surface plays a part in 10% lower friction at low speeds in comparison to conventional products.
Tapered roller bearings may accept large radial and axial loads. Axial loads happen to be absorbed in mere one path. For axial counter support a second bearing attached inverse is required. Suitable for medium speeds.

Higher efficiency transmission systems are seen as key to increasing gasoline economy, so NSK attempt to develop a large reliability bearing capable of overcoming these hurdles.

To boost fuel economy, there’s been a change to using less lubricant and/or lessen viscosity lubricant in transmission systems. Consequently, tapered roller bearings in transmissions will be being at the mercy of increasingly severe lubrication circumstances, increasing the risk of lubrication essential oil film depletion (lean lubrication circumstances), surface destruction, and bearing seizure.
