Deep Groove Ball Bearings – Precision, Durability & Versatility for Industrial Applications

Premium Deep Groove Ball Bearings for Smooth, Reliable Performance

Our deep groove ball bearings are engineered to deliver exceptional radial and axial load capacity, low friction, and long service life across diverse industrial environments. Ideal for automotive systems, electric motors, pumps, conveyor systems, and household appliances, these bearings ensure seamless rotation with minimal energy loss, enhancing equipment efficiency and reducing maintenance costs.

Key Advantages

1. High Load Capacity & Speed: Optimized raceway design and premium steel construction enable high-speed operation (up to [X] RPM) while supporting combined radial and axial loads.

2. Low Noise & Vibration: Precision-ground balls and races, paired with advanced lubrication, ensure quiet, vibration-free performance for sensitive applications.

3. Extended Lifespan: Heat-treated chromium steel (GCr15/SUJ2) or stainless steel (AISI 440C) materials, coupled with anti-wear coatings, resist pitting and fatigue.

4. Versatility: Available in open, shielded (ZZ), or sealed (2RS) configurations for dust, moisture, or high-temperature environments.

5. Custom Solutions: Tailored dimensions (3mm–300mm bore), special tolerances (ABEC-1 to ABEC-7), and specialty materials (ceramic, plastic) upon request.

Rigorous Quality Assurance

- Material Testing: Raw steel is verified for hardness (HRC 58–65), purity, and microstructure uniformity.

- Precision Grinding: CNC-controlled grinding machines achieve raceway accuracy within ±0.001mm.

- 100% Inspection: Automated systems check dimensional tolerance, radial clearance, and surface finish.

- Certifications: ISO 9001, ISO/TS 16949, and compliance with ANSI, DIN, and JIS standards.

Technical Specifications

- Bore Sizes: 3mm–300mm (standard); custom sizes available.

- Accuracy Grades: ABEC-1 (standard), ABEC-3, ABEC-5, ABEC-7 (ultra-precision).

- Cages: Steel, brass, or polymer options for high-speed or corrosive environments.

- Operating Temperature: -30°C to +120°C (standard); high-temperature grease options up to +200°C.

Applications

- Automotive: Wheel hubs, alternators, transmissions.

- Industrial Machinery: Electric motors, gearboxes, pumps.

- Home Appliances: Washing machines, fans, power tools.

- Agriculture & Renewable Energy: Harvesters, wind turbine generators.

PRODUCT DISPLAY:

The bearings produced from CPOS company are used in precision instruments, low-noise motors, automobiles, motorcycles, automation equipment, food packaging machinery, home appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery, printing equipment etc.

Our products need to undergo more than 10 processes such as incoming inspection, cutting, rough grinding of inner and outer rings, fine grinding of inner and outer rings (bainite salt bath), turning, heat treatment, noise and vibration testing, cleaning, adjustment, elimination of unqualified products, assembly, packaging, high quality requirements, our products are not just put on the cut, in order to expedite, in order to finish quickly, the adjustment will not be possible, there will be noise after installation, and the after-sales problem will be big in the later stage.

The production process is controlled according to p5, p6 level. The taper of p6 size is less than 3.0miu, and the standard size is -5miu. The p5 size setting excludes finished products and recycles. Re-test, discharge p0 level, p0 is unqualified and scrapped, and the motor is tested for noise level.
