SKF
Ball Bearing Units for Agricultural Applications
SKF agricultural ball bearing units withstand the harsh seasonal demands of farming equipment: dust, crop residue, fertiliser chemicals, weather exposure, and irregular maintenance. The range includes Y-bearing units with heavy-duty contact seals and high-performance greases that repel water and resist washout during equipment cleaning. Housings are robust cast iron or advanced composite for strength without weight. Shaft locking is via grub screw or eccentric collar, selected for vibration resistance in balers, harvesters, and tillage tools. These units are produced in accordance with ISO standard dimensions, enabling straightforward field replacement and keeping machinery productive in critical planting and harvesting windows.

Trusted by Industry Leaders
Triple-Lip Sealing
Keeps out chaff, soil, and moisture.
Anti-Washout Grease
Stays in place during rain, dew, and pressure cleaning.
Corrosion-Protected Housings
Painted cast iron or composite resist fertiliser and acid.
High Shock Load Tolerance
Through-hardened inserts absorb implement impacts.
Easy Field Replacement
Standard bolt patterns and lock mechanisms simplify servicing.
Wide Temperature Range
-30°C to +100°C for all climate conditions.
Bearing Requirements for Modern High-Speed Balers
Round and square balers operate at high RPM with severe vibration. SKF’s eccentric collar locking prevents inner ring rotation under these conditions, while the heavy-duty seal excludes crop dust and moisture that would quickly degrade standard bearings.
Composite Housings in Agricultural Sprayers and Spreaders
Corrosion from fertilisers and herbicides is a major failure mode. SKF’s composite housed units eliminate rust, reduce weight, and extend equipment life, especially in trailed sprayer wheel hubs and rotating spreader discs.
