204KRR2 Deep Groove Ball Bearing is engineered for high-performance applications in demanding agricultural environments. Featuring double metal shields (ZZ-type), it provides superior protection against dust, moisture, and debris-extending service life in equipment like combine harvesters, seeders, and lawn mowers139.
Key Features & Benefits:
Robust Construction: Made from GCr15 high-carbon chromium steel (HRC 58-62), ensuring exceptional wear resistance and load capacity under shock/vibration349.
High-Speed Operation: Optimized for RPM-intensive tasks (limiting speed: 11,000 rpm with grease lubrication), reducing downtime in harvest seasons4.
Precision Fit: Non-standard inner diameter (20 mm) and width (18 mm) cater to niche agricultural machinery designs, replacing legacy models like 203RRAR1046.
Easy Installation: Compatible with press-fit mounting methods (use soft metal sleeves to avoid roller damage)36.
Applications:
Farm Equipment: Grain conveyors, tillers, balers
Industrial Use: Light gearboxes, conveyor rollers
Replacement Part: Direct swap for worn bearings in/Kubota implements
Quality Assurance: ISO 9001:2000 certified, available in P0/P6 precision grades with OEM customization (min. order: 200 units)9.
