Asymmetrical double tapered roller bearings for tractor transmissions - This results in an optimum compromise between the two development objectives, i.e. energy efficiency and absorbing high loads. A spacer ensures that play between the two inner rings does not exceed the desired range of tolerance and also prevents corrosion in this critical area.


Bearings for agricultural machinery - The advantages of application-specific bespoke bearings

When the going gets tough:
Severe mechanical strain and abrasive particles in the operating environment: bearings for agricultural machinery have to work in conditions which are far from ideal. Standard products are often unsuitable in these cases because they have a very limited service life. However, bearings are available which have been developed specially for agricultural machinery and mounted implements. Joint development projects by bearing and machinery manufacturers focus on reliable seals and component integration.

Asymmetrical double tapered roller bearings for tractor transmissions
NSK has not only developed customised bearings for mounted farming implements. It has also come up with units for tractor power trains. Here is an example. The company designed a bespoke bearing for a tractor gearbox consisting of a double tapered roller bearing with an asymmetrical cage. One of the two rows of tapered roller bearings was given longer rollers, enabling it to absorb very high loads. A shorter roller design was chosen for the other row to minimise frictional losses and therefore energy wastage.

This results in an optimum compromise between the two development objectives, i.e. energy efficiency and absorbing high loads. A spacer ensures that play between the two inner rings does not exceed the desired range of tolerance and also prevents corrosion in this critical area.
