SKF Y-bearing units for agriculture applications
Discover what you can achieve with SKF Y-bearings – developed specifically for agricultural applications
Today’s farmers are under increasing pressure to stay productive for less money, and with less of an environmental impact. But mud, dust, water, sap, straw, stones and more take a heavy toll on the bearings in agricultural applications. Contaminant ingress and lubricant loss from failed seals, as well as locking device problems, often lead to premature bearing failures. These early bearing failures reduce a farm’s output and profitability. For OEMs, premature failures increase warranty costs and can damage customer relationships. SKF agricultural Y-bearing units can prevent such problems for OEMs and end users alike.
The Y-bearings and units assortment includes the ideal solution for each application and specific machine design, making it possible to build more value into the machine design, reduce warranty costs, reduce the number of suppliers – and stay ahead of the competition.

SKF sealing solutions for agriculture applications
SKF high performance sealing solutions provide proven reliability in tough working environments – helping to reduce ownership costs and enhance farm productivity. Selection guidelines for different sealing solutions under various operating conditions are provided in diagram 1.
For extremely contaminated environments, such as agricultural applications, SKF recommends Y-bearings equipped with the patented 5-lip seal on both sides (fig. 1).
SKF agricultural Y-bearings with the 5-lip seal are subjected to a series of extensive laboratory and field tests (table 1).
The diagram below provides a service life comparison in mud in % between an SKF Y-bearing with 5-lip seals and two competitor bearing solutions (offered as the most suitable for extremely contaminated environments).
This is an operational testing – the service life in mud is expressed in %.
The results: SKF Y-bearing equipped with the five-lip seal shown a better service life in mud compared with competitor solutions (offered as the most suitable for extremely contaminated environments (diagram 2).
Y-bearings with a standard inner ring are equipped as standard with an RS1 seal on both sides (fig. 5, designation suffix 2RS1). These seals are suitable for medium contaminated environments and accommodate the highest speed among the seals available for SKF Y-bearings for agricultural applications.
Y-bearings with a standard inner ring with designation suffix VP274 are equipped with standard seals.
SKF locking methods for agriculture applications
This method is the most commonly used in agriculture applications (fig. 7). Even if the eccentric locking collar is preferably used for applications where the shaft rotates in one direction only, it can be used for alternating directions as well especially when loads and accelerations are low.
For additional information, refer to Insert bearings with an eccentric locking collar.
The use of an interference fit is only available for Y-bearings in the 17262..-2RS1 and 17263..-2RS1 series (fig. 10). These bearings and the required housings have to be ordered separately. This locking method is recommended for applications where the direction of the load alternates and where smooth running is a key operational parameter.
For additional information, refer to Insert bearings with a standard inner ring.
