FAFNIR RA 012 NPP 4 4 - A Wide Inner Ring Ball Bearing | 3/4 inch Bore | Heavy Duty Agricultural Sealed Unit
The FAFNIR RA 012 NPP 4 4 - A is a premium wide inner ring ball bearing engineered for demanding industrial and agricultural environments. Featuring a standard 3/4 inch (19.05 mm) bore and a robust outer diameter of 40 mm, this bearing is designed to fit standard light-duty shaft applications while providing superior rigidity. The wide inner ring provides crucial stability and simplifies mounting, often utilized in cast housings or flange units where shaft alignment tolerances may be challenging. The 'NPP' designation signifies high-performance double-lipped contact seals, which effectively retain factory lubrication while providing exceptional protection against moisture, dust, and corrosive agricultural contaminants.
This unit is pre-lubricated and designed for maximum operational longevity with reduced maintenance cycles. Its high dynamic and static load ratings (Cr and C0r) ensure reliable performance under continuous heavy loading, common in conveyor belts, tillers, and specialized farm machinery. The FAFNIR legacy guarantees high precision and material quality, making the RA 012 NPP 4 4 - A an ideal drop-in replacement or original equipment component where reliability and contamination exclusion are paramount to uptime.
