Fertiliser machine without corrosion

• What was needed: igubal spherical bearings Requirements: as the fertiliser is highly corrosive, a permanently corrosion-resistant bearing was required. The bearings also had to be able to align themselves so as to avoid the eccentric inclined resistance of the two bearings.
• Industry: agriculture
• Success for the customer: the igubal spherical bearings do not rust and require no lubrication as they are self-lubricating. This eliminates the need for expensive and cumbersome rubber seals, which the customer used in the previous solution. Overall, this has improved product performance and reduced manufacturing costs.

An agitator shaft is attached to the fertiliser hoppers to prevent loss of fertiliser. This shank had to be attached to the two shaft walls with bearings at both ends, which presented a few challenges.
The fertiliser has a strong corrosive effect on all components in the system, with which the bearings had to constantly cope without any problems. When conventional ball bearings were used, rubber seals were necessary, which complicated the mechanism and made lubrication more difficult.
As the fertiliser box is a welded construction, the bearings used must also be able to align themselves in order to avoid the eccentric inclined resistance of the two bearings.

For the bearings, those responsible decided to use igubal bearings, specifically igubal spherical bearings of type EFGM-16T. Since the spherical bearings were introduced, the problems of the previous solution are a thing of the past. Thanks to their corrosion resistance, they do not rust and no lubrication is required as the bearings are self-lubricating. No separate rubber seals are needed, which makes the solution particularly simple. Overall, this has improved product performance and reduced manufacturing costs. In addition, the user also saves running costs as maintenance has become superfluous. The user benefits from a convenient and problem-free product experience.
