Reduce Downtime with Precision RNA4822 Needle Roller Bearing 120x140x30mm

Equipment failures due to bearing issues cost manufacturers thousands in lost production each year. Many face challenges with inconsistent quality from low-cost suppliers, long lead times for custom sizes, and difficulty finding reliable radial bearings for heavy-duty industrial applications. When your machinery stops, every hour counts—so you need a bearing partner that delivers both performance and reliability.

Engineered for Industrial Machinery Performance

The RNA4822 Needle Roller Bearing is designed to solve these pain points with its 120x140x30mm precision construction and P0-P4 accuracy grades. As an integrated manufacturer with full R&D capabilities and ISO9001 certification, we ensure each bearing meets strict quality standards, making it ideal for machine tools, reducers, and printing machinery where radial load capacity and durability are critical.

Optimal Performance in Demanding Conditions

This radial bearing excels in applications requiring high radial load support with minimal space. Its closed design and bearing steel material provide resistance to wear, while the option for grease or oil lubrication allows adaptation to varying operating speeds and temperatures. Whether used in agricultural equipment or industrial gearboxes, the RNA4822 delivers consistent performance under heavy loads, reducing the risk of unexpected downtime.

Key Technical Features That Matter

Precision rating is a critical factor in bearing performance—the RNA4822 offers P0 to P4 grades, with P4 providing tighter tolerances for high-precision machinery where shaft alignment and minimal vibration are essential. Clearance options (C0, C3, C4) allow customization based on thermal expansion needs; C3 and C4 clearances are particularly useful in applications with temperature fluctuations to prevent binding. The bearing’s design without inner or outer rings enables direct mounting, reducing overall weight and simplifying installation in compact machinery.

Why Quality Bearings Lower Total Costs

Choosing a low-quality needle roller bearing may seem cost-effective initially, but frequent replacements and unplanned downtime quickly erase those savings. Our RNA4822 bearings undergo rigorous quality control in our ISO14001-certified facility, ensuring longer service life and consistent performance. With a 12-month global warranty, we stand behind our products, helping you avoid the hidden costs of premature failure—from repair labor to production losses.
