For machine tool spindles and other positions that call for high radial rigidity, the NSK NN series double row cylindrical roller bearing is built to carry heavy radial loads at considerable speed. Its two rows of cylindrical rollers spread the load evenly, which supports higher load capacity and longer service life. MR Industrial Accessories supplies these bearings to customers across the United States and in several Latin American countries.

The NN prefix identifies a double row cylindrical roller bearing. In part numbers such as NN 3005, NN 3006, NN 3007, NN 3008, NN 3009, NN 3010, NN 3011 and NN 3012, the digits that follow form a dimensional code covering bore, outer diameter and width. Typically the first digit after the letters relates to the dimension series, while the remaining digits indicate the size. Exact dimensions should be confirmed against product tables or by requesting the technical data sheet. If the code is unclear, send the complete part number and our team can quote it.

These bearings suit industries that demand precision and radial load capacity, including metalworking, machine tool building, textiles, printing and material handling. They are commonly found in milling machine, grinding machine and machining center spindles, as well as in power transmission equipment and high-demand rollers. The double row design handles heavy radial loads and moderate tilting moments, so it also appears in mining and cement applications, though other configurations are often preferred there.

When selecting an NN bearing, consider the radial load, rotation speed and environmental conditions. Shaft-to-housing alignment must be verified, because these bearings are sensitive to misalignment. Use suitable tools during mounting and avoid direct blows on the rollers or cage. Lubrication can be grease or oil depending on the application and speed; circulating oil is recommended at high revolutions. Sealing choices depend on the environment: for contaminated conditions, choose configurations with additional seals or protections. Always follow the manufacturer's recommendations for internal clearance and tightening.

Equivalent or interchangeable options may exist under similar designations from other brands, but they are not always directly interchangeable. Precision, internal clearance and cage design can differ between manufacturers. When replacing an existing bearing, the safest approach is to provide the complete part number and operating conditions so a compatible alternative can be evaluated. MR Industrial Accessories can help you find the best option for your application.
