NJ 203 E TNG ZVL 17x40x12 mm Cylindrical Roller Bearing

Technical Specification & Key Features

Robust Single-Row Roller Bearing for Industrial Shafts

The NJ 203 E TNG ZVL is a high-performance single-row cylindrical roller bearing with dimensions 17 mm (bore), 40 mm (outside diameter) and 12 mm (width). Designed for demanding industrial conditions, it provides reliable support for radial loads, offering strong load-carrying capacity and smooth rotation. Its roller-based design ensures greater contact area compared to ball bearings — delivering enhanced load distribution, improved resistance to deformation, and stable performance under heavy loads.

Advantages & Typical Applications

High Load Capacity, Longevity, and Wide Industrial Use

• Exceptional load-bearing performance — the cylindrical roller configuration enables the bearing to handle substantial radial forces, making it ideal for shafts, gearboxes, rollers, and industrial machinery where durability matters.

• Durable and wear-resistant construction — precision-machined rollers and hardened steel rings ensure long service life even under continuous heavy-duty operation.

• Compact dimensions and easy integration — the 17x40x12 mm size fits many standard housings and shaft assemblies, simplifying replacements and retrofits.

• Versatile industrial applications — well-suited for transmissions, conveyors, agricultural machinery, pumps, industrial shafts, rollers, and any mechanical assembly requiring stable support under high radial load.

• Ready-to-install bearing unit — designed for direct mounting in bearing housings or on shafts, reducing setup time and minimizing downtime in B2B production or maintenance environments.

Detailed Product Description

The NJ 203 E TNG ZVL 17x40x12 mm cylindrical roller bearing is engineered to meet the demands of heavy-duty industrial applications. Its roller-based design delivers robust support for radial loads, offering greater contact surface area than conventional ball bearings.
