⚡ Structural Advantages & Heavy-Duty Performance

• 120-Degree Dual Set Screw Locking: Twin grub/set screws offset at 120 degrees provide superior clamping power on 25mm shafting, preventing shaft slippage even under sudden rotational torque and reverse direction loads.

• Spherical Outer Ring Self-Alignment: Precision-ground convex outer surface accommodates mounting misalignment between housing seats and shafts without increasing internal bearing friction.

• Extended Inner Ring Architecture: 34.1mm wide inner ring provides extra shaft seating area, distributing strain evenly and minimizing shaft fretting and vibration.

• Re-Lubrication Feature ("G" Specification): Designed with an outer ring lubrication groove and feed hole, allowing easy grease replenishment during routine maintenance cycles.

• Multi-Lip Rubber Seal with Steel Slinger: Heavy-duty contact seals backed by metal slingers form an impenetrable shield against dirt, dust, slurry, and moisture contamination.

🚜 Agricultural & Industrial Machinery Deployment

• Agricultural Implements & Harvesting: Ideal insert bearing for combine harvesters, balers, seed drills, grain augers, and rotary tillers.

• Material Handling & Conveyors: Essential drive component for belt conveyors, roller beds, sorting lines, and industrial elevator drives.

• Industrial Fan & Pump Assemblies: Fits standard cast iron and stainless steel mounted housings across processing plants and factory automation lines.
