EMQ Grade & High-Precision Deep Groove Ball Bearings

Vetor Group specializes in engineering deep groove ball bearings designed to exceed standard durability parameters.

Designed for Low Friction, Noise, and Long Life Cycles

Deep groove ball bearings are the most widely used bearing type due to their simple design, non-separable nature, and suitability for high speed operation. Our in-house production plant manufactures EMQ (Electric Motor Quality) grade bearings with precise bore sizes ranging from 6mm to 90mm. These components are specifically formulated to support both radial and axial loads in both directions.

Our VETOR brand bearings are characterized by key mechanical advantages:

  • Minimal Noise & Vibration: Extensively tested using specialized dynamic vibration measurement machines to meet Z1V1, Z2V2, and Z3V3 vibration classifications.
  • High-Performance Sealing: Available in double-shielded (ZZ) or double-sealed (2RS) configurations using high-grade nitrile rubber or metallic guards to prevent particulate ingress.
  • Optimized Tribology: Pre-lubricated with high-grade synthetic lubricants tailored to resist extreme temperature spikes and rotational friction.
  • Premium Raw Materials: Machined from high-carbon chromium steel (GCr15), heat-treated to achieve optimal hardness ranges of HRC 60-65.
01

Low Noise & Friction

Designed with precise raceway grooves for high-speed operation with minimal sonic output.

02

High Sealing Integrity

Optimized double seals (2RS / ZZ) prevent contaminants from compromising rotation.

03

Stable Heat Treatment

Advanced heat-treatment processes ensure dimensional stability up to 120°C.

04

Vibration Grade Rating

Rigorous quality checks guarantee EMQ ratings for quiet household appliances.

Global Sourcing: The Advantages of Chinese Bearing Manufacturing

Why sourcing from Cixi, China, offers unmatched cost-efficiency, technical depth, and logistical velocity.

Aggregated Supply Chain

Cixi and the broader Ningbo area house a highly concentrated industrial ecosystem. From premium raw steel sourcing (GCr15), precision steel ball manufacturing, specialized cage production, to heat-treatment service providers, the entire value chain is located within a 50km radius. This geographic aggregation drastically reduces sub-component lead times and component logistics costs.

Advanced Automation

Chinese bearing manufacturers have transitioned from manual labor to fully automated CNC grinding, super-finishing, and automated assembly line operations. Integrated optical inspection systems and automated grading machines ensure high consistency and reduce human error, matching European standards at a fraction of the cost.

Logistical Integration

Proximity to Ningbo-Zhoushan Port, the world's busiest port by cargo tonnage, allows Vetor Group to dispatch ocean freight container vessels daily. Close integration with customs brokers and streamlined logistics protocols means shorter port-to-port durations, reduced storage charges, and reliable ocean route planning.

Macro-Industry Solutions & Application Fields

How Vetor Group bearings serve global industries, from household electronics to heavy-duty off-road recreation.

Precision Solutions Engineered for Real-World Scenarios

Different application fields present distinct friction and loading challenges. Vetor Group doesn't just sell general-purpose bearings; we offer application-specific solutions designed to optimize longevity under various environmental conditions.

Our solutions cater directly to four key sectors:

  • Automotive & Transportation: Providing durable wheel hub units (like VKBA7447), steering column bearings, and transmission bearings designed to endure shock loads, mud ingress, and high rotational speeds.
  • Electric Motors & Home Appliances: Supplying EMQ bearings with Z3V3 vibration grades. Essential for micro-motors, fans, washing machines, and air conditioning units where quiet operation is paramount.
  • Off-Road & Recreational Vehicles: Heavy-duty components built to perform in dirt, mud, and water. Highly reliable seals and robust steel cages are utilized for ATV suspension joints, dirt bike gearboxes, and motorcycle crankshafts.
  • Agricultural & Textile Machinery: High-load spherical roller bearings (like 22317CAW33) and insert bearings that withstand misalignment, heavy loads, and abrasive dust.

Innovation in Bearing Materials and Manufacturing

The bearing industry is undergoing significant technological changes. Demand is growing for higher rotational speeds, improved energy efficiency, and reduced frictional torque. As a forward-looking manufacturer, Vetor Group tracks three major industry trends:

  • Advanced Metallurgy & Ceramic Hybrids: The use of silicon nitride (Si3N4) balls in standard steel rings helps minimize electrical erosion in EV motors and generator applications.
  • Environmentally-Friendly Greases: Sourcing biodegradable and high-temperature synthetic lubricants that reduce volatile organic emissions while extending service life.
  • Smart Manufacturing & Quality Control: Incorporating real-time AI visual inspection on production lines to detect structural defects before packaging.

Vetor Group applies these developments to our deep groove and EMQ-grade bearing lines to keep our products aligned with international industry needs.

Frequently Asked Questions (FAQ)

Find answers to common questions about sourcing, technical specifications, and logistics.

What materials are used in VETOR bearings?
We use high-carbon chromium bearing steel (GCr15), which is equivalent to AISI 52100 in the USA, SUJ2 in Japan, and 100Cr6 in Europe. This material is heat-treated to HRC 60-65 to ensure high fatigue resistance and structural stability.
What does EMQ stand for, and where is it used?
EMQ stands for Electric Motor Quality. It designates bearings designed and tested for quiet operation and minimal vibration. EMQ bearings are used in household appliances, fans, medical devices, and micro-motors where noise reduction is critical.
How does Vetor Group handle quality control?
Our manufacturing processes are certified to the ISO 9001 international standard. We conduct multi-stage quality checks, including raw steel chemical analysis, dimensional tolerance inspections, roundness and roughness measurements, and noise testing (Z-value ratings).
What are your standard delivery times and shipping ports?
Standard order production takes 7 to 20 days depending on order size and customization requirements. Our factory in Cixi is close to Ningbo Port and Shanghai Port, which helps ensure efficient domestic transport and prompt ocean freight dispatch.
Do you support custom bearing sizes and OEM branding?
Yes, we provide full OEM and ODM services. We can customize internal clearances (C2, C3, C4), seal materials (NBR, rubber, steel), greases, and custom packaging. We also support engraving custom brand logos on the bearing shields.
