RKB NNC V series bearings are double-row cylindrical roller bearings built for high radial loads and moderate speeds. They suit equipment that needs stiffness and durability, including heavy machinery, mining systems and power transmission drives. MR Industrial Accessories supplies these bearings and helps you match the right code to your application.
Reading the code helps you narrow down the options. NNC identifies a double-row cylindrical roller bearing with a steel cage and a high-capacity layout. The trailing V points to a construction variant, often a groove or a particular mounting configuration. Size information appears in the digits that follow: NNC 48/500 V and NNC 4830 V are two examples. In some codes the bore is given directly in millimeters, such as 500 or 530; in others the full number corresponds to a dimension series. The most reliable way to select is to provide the exact code from the equipment nameplate or the measured shaft and housing dimensions.
Typical service environments include cement, steel, mining and material handling operations. You will find these bearings in gearboxes, gear cases, conveyor rollers, mills and crushing equipment. Their capacity to absorb heavy radial loads and shock loads makes them a fit for dusty, vibrating sites with moderate temperatures. Paper machines and large transmission systems also use them.
Selection should account for radial and axial load, speed and operating conditions. Check the sealing arrangement, because NNC V variants may include plates or grooves that affect contaminant protection. Internal clearance and lubrication matter as well; pick a lubricant that matches the temperature and speed of the application. During mounting, align shaft and housing carefully to prevent parasitic loads, and follow the adjustment practices used for cylindrical roller bearings.
Cross-referencing between brands is common when replacing these bearings. RKB NNC series units can be interchanged with bearings from other makers that share the same designation and dimensions, including NN or NNC series from other firms. Tolerances and internal clearance can differ between manufacturers, so verify them before installation. If you have a code from another brand, send it over and we will identify a compatible option or quote the exact code you need.

Frequently asked questions
- What does NNC V mean in an RKB bearing code?
- NNC stands for a double-row cylindrical roller bearing, and the V indicates a construction variant, such as a specific groove or mounting configuration. The numbers that follow define the size, either as a bore diameter in millimeters or as a dimension series code.
- Where are NNC V bearings commonly used?
- They appear in applications that require high radial load capacity, including gearboxes, gear cases, mills, crushers and mining or cement equipment. The design handles dusty, vibrating conditions and high loads.
- How do I get a quote for an NNC V bearing?
- Send the exact code from your equipment or the shaft and housing measurements by WhatsApp or email. MR Industrial Accessories will quote the RKB bearing you need and respond promptly.
