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

The bearings are separable. This implies the bearing parts can be fitted independently of each different. The bearings are supplied without seals. They may be lubricated with grease or essential oil from the side.

The rollers are processed to create pore-like micro indents in the surface of the steel (rolling contact area and roller brain). This microstructure helps keep an oil film that is well suited for tapered roller bearing applications. Improved oil film retention significantly inhibits surface damage, reaching more than eight circumstances higher strength and equal or increased seizure resistance in comparison to conventional products.
Superior lubricant oil accumulation and retention (better to form oil film) in the roller surface plays a part in 10% lower friction at low speeds compared to conventional products.
Tapered roller bearings can accept great radial and axial loads. Axial loads happen to be absorbed in mere one course. For axial counter support a second bearing installed inverse is required. Suitable for medium speeds.

Larger efficiency transmission systems have emerged as key to bettering fuel economy, so NSK set out to develop a substantial reliability bearing with the capacity of overcoming these hurdles.

To boost fuel economy, there’s been a shift to using less lubricant and/or lessen viscosity lubricant in transmitting systems. Subsequently, tapered roller bearings in transmissions are being subject to increasingly severe lubrication circumstances, increasing the risk of lubrication oil film depletion (lean lubrication circumstances), surface harm, and bearing seizure.
