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

The bearings are separable. This means the bearing parts could be fitted independently of each additional. The bearings are provided without seals. They might 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 surface area and roller mind). This microstructure helps preserve an oil film that’s perfect for tapered roller bearing applications. Improved essential oil film retention significantly inhibits surface damage, reaching more than eight instances higher durability and equal or better seizure resistance in comparison to conventional products.
Increased lubricant oil accumulation and retention (simpler 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 may accept huge radial and axial loads. Axial loads happen to be absorbed in only one route. For axial counter support a second bearing installed inverse is required. Ideal for Tapered Roller Bearing china medium speeds.

Larger efficiency transmission systems have emerged as key to increasing gasoline economy, so NSK set out to develop a large reliability bearing capable of overcoming these hurdles.

To boost fuel economy, there’s been a shift to using less lubricant and/or decrease viscosity lubricant in tranny systems. As a result, tapered roller bearings in transmissions are being at the mercy of increasingly severe lubrication circumstances, increasing the risk of lubrication oil film depletion (lean lubrication conditions), surface destruction, and bearing seizure.
