Corrosion-free bearings achieve over 10 years service life in manure spreader
In this boundary spreader, heavy-duty igubal bearings guarantee failure-free operation.
No more turning off and still always dosing with the highest precision - with the AXIS 50.1 W, these wishes can be fulfilled. The igubal plastic clevis joints are combined with a KMF hydraulic cylinder in the boundary spreader device. A dynamic test of 2 times 100 hours at -20°C and a block load of 4,000 N reflects a service life of over 10 years. This is underlined by the vibration-dampening specifications and the high load capacity of the clevis joints.Profile
- What was needed: igubal clevis joints
- Requirements: Corrosion-free as well as heavy-duty bearing components were needed that would function continuously even in cold temperatures.
- Industry: Agriculture
- Success for the customer: The igubal bearings were simultaneously put to the test twice over a period of 100 hours each at - 20 °C and under the influence of a block load of 4,000 N. This corresponds to a service life of 10 years. The vibration-dampening specifications as well as the high load capacity and corrosion resistance of the clevis joints contribute to this. They are also a cost-effective alternative to steel bearings.

Problem
The fertiliser spreaders from RAUCH Landmaschinenfabrik GmbH, such as the model AXIS 50.1 W in this case, dose with the highest precision when spreading fertiliser evenly on the field. Here, all components used in the fertiliser spreader must be corrosion-free and designed for the high content of ammonia in the fertiliser. This is also the case in the boundary spreading device, which limits the spreading area of the fertiliser to enable more targeted and efficient spreading. Here, clevis joints are used in combination with a KMF hydraulic cylinder, which must be able to permanently withstand the adverse conditions.Solution
The components used as bearings in the fertiliser spreader today are igubal clevis joints made of plastic. They are combined with a KMF hydraulic cylinder in the boundary spreading device. The high demands placed on the solution in fertiliser technology are demonstrated by the dynamic test that the new system had to undergo. The boundary spreading device was thus put to the test twice simultaneously, each time for a period of 100 hours at - 20°C and under the influence of a block load of 4,000 N. These simulated test conditions correspond to the loads that the system would encounter in practical use within 10 years. The long service life can be explained in part by the vibration-dampening specifications as well as the high load capacity and corrosion resistance of the clevis joints. They are also a cost-effective alternative to steel bearings.
