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.
Taking a closer look at one particular mounted farming implement is a good way to illustrate the demands placed on bearings units in the field of agricultural engineering. Harrows are used to prepare the soil for sowing. They have disc-shaped attachments which run through the soil and thoroughly mix the uppermost layer to create a consistent seedbed. The discs have to rotate regardless of the terrain, so easy running is a key criterion.
Customised angular-contact ball bearings for compact disc harrows
It should come as no surprise that the ambient conditions for bearings in the individual discs are far from favourable. Harrows work in dirty, dusty environments, so the bearing
