Our expertise for your industry
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)
ABEG® in agricultural technology
High loads and low speeds place special demands on lubricants because load ratings alone cannot contribute to a long service life. Accordingly, it is important to focus on heavy-duty roller bearing greases and excellent sealing technology. Nevertheless, preventive maintenance work means that conventional and quickly obtainable products are still in demand. By using the ABEG® method and dividing the product range into common and less common items, we help engineers achieve savings wherever it makes sense – for example by switching to lower-cost roller bearings in a different performance class that nevertheless meet the requirements for the respective application all along the line.
Product recommendations for agricultural technology
Housing bearings in a wide variety of designs and flange styles
Housing bearings are particularly well suited for use in robust machines, and Findling offers them in many designs in its product range. The agricultural sector primarily uses housing bearings because of their robust and corrosion-resistant properties. Findling Wälzlager GmbH offers a wide variety of designs and flange styles in all four ABEG® performance classes. This includes designs with caps to protect against rotating shaft ends and corrosion, other variants for corrosion protection in graded price and performance classes, as well as solid construction cast housings, which are a new addition to the product range, particularly resilient, and have load limits in stationary, flanged and axially loaded operation that are higher than that of any other products available on the market.
Corrosion protection in roller bearings
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.
FYH’s “extra solid” housing bearings series
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.
Die-cast aluminum and sheet metal flange bearings
Corrosion resistance, compact dimensions, and low weight: these are the advantages of die-cast aluminum bearings. The clean and silver series, which are suitable for high loads, are worth mentioning in particular here. The housings of these bearings are made of very light die-cast aluminum. Together with a stainless steel bearing insert, these solutions are corrosion resistant. By combining them with bearing inserts made of standard steel, it is possible to create very compact and easy-to-install bearing solutions with a shaft diameter of 8 mm. Findling also has galvanized steel sheet housings and stainless steel designs in its product range in which a bearing insert is clamped. Three models are available: plummer block (PP), 3-hole flange bearings (PFL), and 2-hole flange bearings (PFD). These solutions are very small, compact and light. The flange bearings are used, for example, in closing mechanisms in which long shafts are used to, for example, open and close bags. Flange bearings are also used in the drive rollers of conveyor lines and tracks.
Stainless steel roller bearings
Protected against corrosion
The use of stainless steel types such as AISI440C, AISI420, AISI316L or zinc/iron or zinc/nickel coatings allows us to achieve excellent corrosion protection.
Suitable for use with foods
Thanks in particular to FDA-approved, biologically degradable H1 greases and resistance to leaching due to chemical cleaning agents
Corrosion-resistant Xclean series roller bearings are ideally suited for the high demands of food packaging. They ensure the best possible hygiene standards, optimum corrosion protection, and resistance to aggressive chemicals. In Findling Wälzlager’s extensive stainless steel portfolio, you will find, among other things, yoke type track rollers and cam followers, needle-roller bearings, housing bearings, self-aligning ball bearings, thrust bearings and deep-groove ball bearings. Customers can choose the base material that is best suited for their application, for example stainless steel types AISI440C, AISI316L, AISI304, AISI420 or 100Cr6 roller bearing steel with zinc/iron or zinc/nickel coatings. Ceramics and high-performance materials such as AISI630 or titanium are also possible. Last but not least, seals are very important in this area of application because rough operating conditions necessitate proper protection of the inside of the bearing. If chemical resistance is required, seals made of HNBR, ACM and FKM can also be offered in addition to seals made of NBR. Special greases, in particular with H1-approved food-compatible grease, round out the product range.
Housing bearings with outstanding sealing technology
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.

Findling Wälzlager’s special product range is divided into four series: Xforce, Xspeed, Xtemp, and Xclean. This allows different requirements to be met with respect to operating conditions. Xforce bearings are solutions for high loads at low rotation speeds in which there are unfavorable tribological conditions and lubrication film build-up cannot reliably occur with standard solutions. During the development of the Xspeed series, on the other hand, high speeds and energy efficiency were the focus. The Xtemp series ensures temperature stability in excessively hot or cold conditions. The Xclean series provides robust bearing technology for corrosive ambient conditions as well as special designs for clean room applications.
