Rolling bearings

Rolling bearings are bearings that support loads and function with the rolling motion that occurs between parts moving relative to one another.

Plummer blocks

Plummer blocks are assemblies consisting of spherical roller bearings or self-aligning ball bearings, and a housing with a bolt hole mounting seat parallel to the bearing center axis.

Bearing units

Bearing units are unit products with ball bearings mounted within housings.

Sliding bearings

Slide bearings are the name of bearings that allow relative movement of sliding friction shafts and surfaces. Sliding bearings include oil-impregnated sintered bearings and plastic sliding bearings, as well as Hydrodynamic Bearphite.

Precision machinery and parts

Constant velocity joints (CVJ)

Constant velocity joints (CVJ) are parts of driveshafts that are used to transmit rotational movement, so that both the input shaft and output shaft are always rotating efficiently at a constant speed, regardless of their angle, ensuring that torque is transmitted smoothly.

Auto tensioners

An abbreviation of automatic tensioner, auto tensioners are devices that adjust and maintain the tension of the timing belt or timing chain in a vehicle engine. They play a vital role in extending the operating life of the belts or chains, and also help to reduce excess operating noise.

Clutches are mechanical devices that control how rotational force is transmitted. They include one-way clutches that transmit force in one direction and run free in the opposite direction, two-way clutches that can be switched to transmit or run free in either direction, and torque diode TM that rotates the output shaft when the input shaft rotates.

Electric Motor and Actuator

The Electric Motor and Actuator is a module product that combines NTN's core technologies of bearings and ball screw product technology with motor design technology and electrical control technology.

Sensor Related Products

Sensor related products are machinery used on mechanisms that mainly detect information about the axis of rotation. Their role is to detect information about such as the speed, direction and angle of the axis of rotation and then control rotating bodies.

Linear motion products

Linear modules are linear motion units which incorporate high-performance linear guide bearings into an aluminum frame, and move a work stage through motor drive. A linear guide is a type of linear guide bearing comprised of a guide rail, runner block and rolling element. In all cases, size selection and design can be done to suit the application and purpose, with sizes ranging from small to large, and options such as long stroke and heavy object transport.

Parts feeders

Parts feeders are devices that automatically align a wide variety of work pieces such as mechanical parts, electronic parts, plastic parts, chemicals, pharmaceuticals and food products, and feed them to automated machinery through chutes or other delivery systems.

EV System

EV systems cover motor, sensor and control technology for electric vehicles (EV). In-wheel Motor System and Two Motor On-board Drive System have been developed and proposed as drive systems, together with Electromechanical Brake System with Parking Brake for braking, and Rear-wheel Independent Steering System for steering.

Condition monitoring system (CMS)

The Condition Monitoring System (CMS) are devices used for monitoring devices remotely, and detecting and diagnosing failures by regularly acquiring data from mounted sensors covering characteristics such as vibrations, displacement and temperature.

Photo: Composite Material Products

Composite Material Products

Composite material products include sliding bearings and electronic and machine parts made of plastic (BEAREE), sintered metal (BEARPHITE) and magnetic material (NIKAMET), as well as elemental parts and products featuring a combination of these composite materials.

Aftermarket parts and maintenance
