Industrial machinery operators know the cost of unexpected downtime—missed deadlines, maintenance overtime, and production losses add up fast. When bearings fail prematurely due to poor precision or material quality, the impact ripples through your entire operation. Sourcing reliable, high-precision bearings that meet exact specifications can feel like navigating a maze of generic options and long lead times.
Our RNA4864 Needle Roller Bearing delivers the reliability industrial machinery demands. With dimensions 350x400x80mm and precision ratings from P0 to P4, this radial needle roller bearing is engineered to handle heavy radial loads in tight spaces—ideal for gearboxes, machine tool spindles, and conveyor systems. Backed by our ISO9001 certified production process and 12-year manufacturing expertise, we ensure consistent quality that minimizes unexpected failures.
The RNA4864 excels in high-load, low-speed industrial environments where space is limited. Its closed-type design and bearing steel construction provide durability against contamination and wear, making it suitable for harsh conditions in manufacturing plants and construction sites. Whether powering a printing press or supporting a conveyor system, this bearing maintains stable performance under continuous operation, reducing the need for frequent replacements.
Precision rating directly impacts machinery accuracy—our P4 grade option ensures minimal radial runout, critical for CNC machine tools requiring tight tolerances. Clearance options (C0, C3, C4) allow customization for thermal expansion in high-temperature applications like steel mills. The bearing’s radial load design efficiently distributes stress, extending service life in heavy machinery. With lubrication flexibility (grease or oil), it adapts to diverse operating conditions, from clean factory settings to dusty construction sites.
Choosing a low-cost, uncertified bearing may save upfront, but the hidden costs are steep. Premature failure can damage costly machinery components, require emergency repairs, and halt production—often costing 10x the bearing’s price. Our RNA4864 meets international standards, backed by ISO14001 environmental certification and rigorous quality control. With a 12-month global warranty and defect replacement guarantee, we stand behind every bearing, ensuring long-term reliability that lowers your total cost of ownership.
