Example 2: Bearing Supports for Shakers with Effective Seals The seals of bearing supports in shaker shafts are subject to extreme dust exposure especially in dry countries, for example during the soya harvest in Argentina. Here, the use of our proven three-lip seals is vital. The shaker Plates must be guided very close to each other in order to achieve a high harvest yield. However, in order to prevent the plates coming into contact with each other, the bearing support must have high tilting rigidity. We have implemented this successfully by profile grinding the ring raceways (four point contact Ball bearings) in the shape of a gothic arch. A lightweight plastic tire rounds off this economical system solution. Example 3: Track rollers that Generate an Economic Benefit in Tedding Machines INA track rollers are used to control the tine arms in hay tedding machines. Each arm is controlled by a roller. Using these bearings generates a measurable economic benefit, since they are small, resistant to wear and reliable. They seldom require relubrication thanks to their large grease reservoirs and particularly effective seals. The user benefits from reduced maintenance requirements and lower costs. The technical superiority of INA track rollers compared with conventional Components is due to the optimized outer raceway profile. The Hertzian pressure at the contact point is always lower than conventional track rollers – with or without tilting. This minimizes wear on the mating track, which has a positive influence on the operating life of the entire system.
