203 KRR2 C3 PFI 16.2x40x18.3 Agricultural Insert Ball Bearing

Engineered for Seasonal Agricultural Workloads

The 203 KRR2 C3 PFI agricultural bearing is specifically developed for farming machinery operating under extreme exposure to dust, crop residue, moisture and vibration. Unlike standard deep groove ball bearings, the KRR2 design incorporates reinforced sealing technology and optimized internal geometry to ensure dependable performance during intensive harvesting and field operations.

Its compact dimensions of 16.2x40x18.3 mm make it suitable for numerous agricultural assemblies where continuous operation, contamination resistance and long service intervals are essential. The C3 internal clearance allows the bearing to accommodate thermal expansion and fluctuating loads commonly encountered in modern agricultural equipment.
