  • in Ball Bearings

    NSK are manufacturers of ball bearings that can handle moderate to heavy radial loads, and low to moderate thrust loads in either direction. Specific types of ball bearings offered by NSK include deep groove radial type (high quality steel, high speed, radial and axial loads), Max Type (heavy radial loads and low speeds), double row, self aligning type (high quality steel, small contact angle, sealed versions available), Mast Guide (high load capacity), super precision, and angular contact designs. Other types of bearings offered by NSK include spherical, tapered, cylindrical, super precision, thrust and needle roller configurations. NSK also manufactures thin section double row angular contact ball bearings and pillow blocks.

  • in Cylindrical Roller Bearings

    With NSK's cylindrical roller bearings the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds. Different types offered include NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings). The outer and inner rings of all types are separable.

  • in Linear Slides

    NSK offers linear guides in a variety of configurations, including: linear shafting, monocarrier actuators, mechatronics, ball screws, linear stages, linear roller/ball guides, etc. Linear stages feature K1 lubrication, easy installation capabilities, high load capacities, easily bolted modules, and they work for pick/place applications.

  • in Needle Roller Bearings

    NSK is a manufacturer of radial and thrust needle roller bearings. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam and roller followers. Thrust bearings include thrust needle bearings. Download their catalog. NSK also produces ball and roller bearings, as well as bearings for the steel industry.
  • in Roller Bearings

    NSK are manufacturers that produce a full range of roller bearings. Types include needle, spherical, cylindrical, thrust and tapered. NSK cylindical types have a high radial load capacity at high speeds, and come in single row and double row configurations. Their needle roller bearings are either radial or thrust, whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. They include application-specific cam followers, and roller followers. NSK thrust roller bearings are available with cylindrical or spherical rollers, are suitable for heavy loads and have high axial rigidity with self aligning capability. The E type offers a pressed cage. Spherical types come in EA, C, CD or CA type, and are designed for high load capacity. Some come with a steel cage. Type EA has especially high load capacity and a high strength cage.

  • in Rolling Mill Bearings

    NSK is a manufacturer of a range of rolling mill bearings which support the rolls that roll steel, and other primary metals, to a specified size and shape.

  • in Sealed Ball Bearings

    NSK manufactures sealed ball bearings designed for extreme accuracy, high rotational speed, quiet and smooth running, minimum friction and heat generation, and controlled rigidity. Sealed ball bearings are available in deep groove, thrust, angular contact, super precision, self-aligning and Spacea designs.

  • in Spherical Bearings

    NSK is a manufacturer of spherical roller bearings designed for high load capacity with pressed steel or machined brass cages.  An oil groove and holes are provided in the outer ring to supply lubricant. CAD drawings are provided. Other bearing types offered by NSK include roller and ball bearings, and bearings for the steel industry.

  • in Spherical Roller Bearings

    NSK is a manufacturer of spherical roller bearings which are designed for high load capacity. Some types have pressed steel cages, some have machined brass cages, and some have especially high load capacity, feature low torque and have a high-strength cage.
  • in Stainless Steel Ball Bearings

    NSK Americas designs special environment products including stainless steel ball bearings for high humidity environments.

  • in Tapered Roller Bearings

    NSK is a manufacturer of tapered roller bearings that use conical rollers guided by a back-face rib on the cone. These bearings are capable of taking high radial loads and axial loads in one direction.
  • in Thin Section Bearings

    NSK is a manufacturer of a series of thin section ball bearings in metric and inch designs.  Features include a low frictional and irregular torque to ensure efficient power transmission and smooth rotating performance.
  • in Thrust Bearings

    NSK Ltd. offers thrust cylindrical and spherical roller bearings. Thrust cylindrical roller bearings are thrust bearings with cylindrical rollers and machined brass cages. They have high axial rigidity that can only support heavy axial loads. Thrust spherical roller bearings are thrust bearings with convex rollers and machined brass cages for horizontal shaft or high speed application. If requested, the E type offers a pressed cage for high load capacity. They are self aligning and resistant to mounting error or shaft deflection.

  • in Thrust Bearings

    NSK offer ball thrust bearings and spherical thrust bearings. Double direction thrust ball bearings support thrust loads in both directions at high speeds. They are made of washer like bearing rigs with raceway grooves for the balls. NSK Spherical Thrust bearings support extremely heavy thrust loads in a single direction at low to moderate speeds; it can support some radial load while thrust load is imposed.  The spherical shape of the outer ring raceway was designed especially to handle misalignment.

  • in Thrust Roller Bearings

    NSK is a manufacturer of thrust roller bearings available with cylindrical or spherical rollers. These bearings can handle only axial loads but can be used for heavy loads and have high axial rigidity. Spherical thrust roller bearings are self-aligning and contain convex rollers.
