1. Brand Technical Accumulation: Japanese Precision to Build Full-Working-Condition Bearing Solutions

Japan NMT Entem Bearing has decades of experience in R&D and manufacturing of precision bearings, with a complete Japanese bearing full-process production system: refined forging of special bearing steel → graded isothermal quenching → mirror ultra-precision grinding of raceways → differentiated sealing assembly → long-life lubricant filling → multi-dimensional factory inspection. We abandon homogeneous low-cost rough-processed products and take working condition customization as the core R&D logic. Targeted product development is carried out for five application scenarios: high-speed precision, heavy-load impact, corrosion and humidity, low and high temperature, and lightweight narrow installation space. It breaks the industry pain point that a single bearing model cannot adapt to complex composite working conditions, realizes accurate model selection and matching for bearings at multiple parts of one device, and reduces spare parts types and operation and maintenance costs of the whole machine.

2. Structural and Performance Advantages of 8 Core Product Lines

Deep Groove Ball Bearings (General Main Series 6)

Adopt integral quenching of high-purity bearing steel, two sealing schemes of double rubber seal and iron seal, filled with long-life temperature-resistant grease before delivery, featuring low friction coefficient, smooth rotation and outstanding mute effect. Suitable for conventional rotating points of motors, fans, water pumps, conveying rollers and general automation equipment. Spot goods cover all sizes of 6000, 6200 and 6300. SUS440C stainless steel can be used for mild corrosion environments.

Cylindrical Roller Bearings (NU/NJ/NUP Heavy-Duty Series)

Linear contact bearing structure with solid thickened cage and widened raceway design, radial bearing capacity is more than 50% higher than ball bearings, supporting oil groove refueling maintenance on outer ring. Mainly used for heavy-duty transmission points such as mine reducers, winches, steel rolling equipment, cement kiln support rollers and shield machines. Non-standard customization of double-row and four-row heavy-duty bearings is available to resist continuous vibration and instantaneous peak overload.

Tapered Roller Bearings (302/32000 Series)

Detachable inner and outer ring structure, which can bear radial force and unidirectional axial force at the same time. Paired use can balance bidirectional axial load, and clearance can be adjusted during assembly. Widely used in automobile differentials, axles, construction machinery wheel hubs, loader transmission shafts and reducer bevel gear supports. It has strong anti-overturning moment and adapts to bumpy off-road heavy-load working conditions.

Precision Angular Contact Ball Bearings (Series 7 for Machine Tools)

Multiple contact angles of 15°/25°/40° are optional, with P4/P5 high-precision grade and lightweight resin cage, excellent temperature rise control during high-speed operation, which can be installed with DB/DF/DT paired preload. Used for CNC machining center spindles, high-speed grinders, precision testing instruments and servo motor spindles to strictly control radial runout and ensure equipment processing accuracy.

Stainless Steel Anti-Corrosion Bearings (SUS304/440C)

Integral stainless steel material with nitriding anti-corrosion strengthening treatment, free from erosion by seawater, salt spray, acid-base chemicals and humid water vapor, no risk of failure due to rust and pitting corrosion. Suitable for seafood processing equipment, electroplating production lines, chemical stirring, offshore wind power, wharf machinery and outdoor water conservancy equipment, and the service life of maintenance-free anti-corrosion is greatly extended.

Lightweight Thin-Wall Bearings for Robots

Ultra-thin cross-section structure with wall thickness optimization for weight reduction, retaining rated load capacity in an extremely small installation space, improving the rotational response speed of robot joints and reducing mechanical inertia loss. Suitable for 6-axis industrial robots, collaborative robots, servo joints and precision rotary platforms to realize miniaturized integrated design of equipment.

Special Bearings for New Energy Vehicles

Hybrid ceramic rolling elements + low-friction sealing structure, less heat generation under high-speed working conditions and low energy consumption loss, effectively improve the working efficiency of electric drive assembly, reduce vehicle power consumption and optimize driving noise. Suitable for new energy drive motors, reducers, wheel hub units and air conditioning compressor bearings to meet the durability requirements of one million kilometers for new energy vehicles.

Self-Aligning Roller Bearings (222/223 Series)

Double-row spherical roller self-aligning structure, which can compensate for shaft bending and installation concentricity errors, with excellent resistance to vibration and eccentric load. Suitable for heavy equipment with high tolerance requirements for coaxiality such as large wind turbine spindles, ball mills, drying drums and paper making press rollers.

3. Main Application Industry Scenarios

High-End Precision Equipment Manufacturing

CNC lathes, machining centers, grinder spindles, precision testing instruments and automated servo modules rely on angular contact precision bearings to maintain long-term processing accuracy and reduce workpiece scrapping caused by spindle runout.
