Agricultural machines (tractors, disk harrows, rotary harrows, seed drills, knife cutter bar or balers) must be designed for rough operating conditions. The equipment should be capable of withstanding extreme loads . After all, they are exposed to dirt, moisture and extreme temperatures. This makes it all the more important to make the right choice from an extremely varied product range when it comes to machine elements as crucial as bearings. Findling Wälzlager GmbH offers application-specific bearing solutions for manufacturers of agricultural machines and attachments.
- easy to maintain and can be relubricated
- robust sealing technology to protect against dust and high-pressure cleaners
- high-strength materials (cast steel)
Equipment for tillage, such as trench rollers and seed drills, is directly exposed to corrosive media such as rainwater, plant protection products or agricultural manure. It is therefore important for components to be resistant to corrosion. Findling offers premium quality housing bearings specifically for these applications that are particularly well protected against corrosion. Among other things, the product range includes products with surface-coated housings that are characterized by excellent performance in the salt spray test according to DIN EN ISO 9227. The targeted surface treatment, for example with nickel, significantly increases the service life of the bearing technology. Zinc or zinc/iron coatings, for example, which provide protection under adverse conditions, are also possible for bearing inserts. These coated inserts are less expensive than comparable stainless steel designs and can withstand high loads.
When P-series plummer block are flange-mounted (C), the unit’s load capacity is reduced by about 70%. This makes the cast housing the critical component, while the bearing insert is automatically oversized. This is a less than satisfactory situation for design engineers, who today have to pay very close attention to costs.
The new “extra solid” series housing bearings by FYH, whose products Findling has been selling in Germany for 30 years, offer a solution to this. For example, the load limit of a P-205 during operation (C) increases from 38 kN to 52 kN. This is a 36% improvement and makes it possible to downsize, which saves costs and installation space. FYH thus once again proves that it is rightfully the key product in Findling Wälzlager GmbH’s premium segment.
FloBack and flinger ring
UC series bearing inserts come with effective sealing as standard. The flinger ring rotates with the inner ring and immediately slings away coarse dirt upon impact. The FloBack seal located behind the flinger ring protects the bearing interior against fine dirt.
Three sealing lips
L3 seals can be ordered as an optional addition to all UC series housing bearing inserts. The increased friction allows these seals to be used for low to high speeds.
Our premium manufacturer FYH meets the increasing demands for functioning protection against contamination with various seal designs that are incorporated into the bearing and can be supplemented by additional accessories. Steel sheet caps are clipped into a groove in the housing (E design = with groove). The interior can be filled with grease to improve the sealing effect even further and to bind dirt. Cast caps can be screwed onto the corresponding housing to protect against very coarse dirt (F design). FYH offers backside guards to ensure that flange bearings are better protected from the rear.
