Established in 2005, VETOR GROUP has positioned itself at the cutting edge of manufacturing and exporting elite mechanical components. Our production facility specializes in crafting premium deep groove ball bearings, custom tapered and spherical roller bearings, and EMQ-grade (Electric Motor Quality) bearings.
Headquartered in the industrial center of Cixi City, Zhejiang Province, along Hangzhou Bay, we sit within a highly efficient logistical nexus. Only 90 minutes from Hangzhou Xiaoshan International Airport and Ningbo Lishe International Airport, and minutes away from the ports of Shanghai and Ningbo, our transport network guarantees rapid transit to partners in over 30 countries.
High-load industrial environments demand bearings capable of handling extreme axial forces, radial forces, and misalignment. Let us examine the design principles that make these components essential for modern machinery.
Tapered roller bearings feature conical rollers and raceways arranged to converge at a common point. This geometric layout allows them to handle combined heavy radial and thrust loads. In heavy industries like mining, construction, and gearboxes, these bearings prevent premature failure under high stresses.
Spherical roller bearings utilize two rows of barrel-shaped symmetrical rollers running in a common spherical outer ring raceway. This allows the inner ring, rollers, and cage to tilt, compensating for shaft deflection and misalignment caused by heavy loading or frame distortions.
By using premium clean steel, high-precision cages, and polished rolling elements, our VETOR bearings operate with minimal friction. This low-friction design reduces heat generation, eliminates abnormal noise, and extends system service life in critical applications.
Industrial buyers must balance cost efficiency with total operational reliability. Sourcing from VETOR GROUP addresses these core requirements through several key benefits:
We monitor every batch of high-carbon chromium steel (GCr15) from raw material receipt to finished assembly, ensuring structural integrity and consistent performance.
By shipping direct from our facility near Ningbo and Shanghai ports, we minimize third-party markups and streamline customs clearance to deliver components in 7 to 20 days.
We offer tailored dimensions, specialized clearances, and custom sealing options (such as NBR, Polyurethane, or Viton) to meet unique environmental and application demands.
Beyond premium bearings, VETOR GROUP manufactures and supplies high-performance components across automotive, power sports, and recreation sectors.
Our VETOR brand includes deep groove ball bearings and EMQ-grade bearings (6mm–90mm). These low-noise, low-friction products are engineered for household appliances, electric motors, medical gear, and heavy machinery.

We ship in strict accordance with contract parameters. Our proximity to domestic ports allows us to maintain stable lead times for global orders.
Our production facility utilizes automated manufacturing equipment, high-accuracy grinding systems, and digital measuring tools to ensure consistent quality.
Our processes comply with the ISO 9001 standard, and our quality control measures are regularly validated by international inspection organizations.
Below we address key technical questions regarding tapered and spherical roller bearings to help engineers and procurement managers optimize their selections.
Tapered roller bearings are designed with conical rollers and angled raceways. This profile allows them to distribute combined radial and axial thrust loads along a wider contact line. In contrast, deep groove ball bearings support point contact, which makes them highly efficient for radial loads but less suited for high axial forces or extreme thrust stresses.
Spherical roller bearings feature two rows of barrel-shaped rollers situated inside a spherically curved outer ring raceway. This allows the inner assembly to adjust to misalignments and shaft deflections. Our designs are engineered to handle misalignments up to 1.5 to 2 degrees without reducing the bearing's rated service life.
We utilize GCr15 high-carbon chromium bearing steel that has undergone strict heat treatment processes. This treatment creates a tempered martensitic microstructure that provides high hardness and wear resistance, helping prevent premature fatigue and subsurface cracking under heavy operational loads.
Our Electric Motor Quality (EMQ) bearings are manufactured using automated finishing processes. Every production run is tested using acceleration and velocity instruments to verify vibration compliance. This quality control helps ensure quiet, low-noise performance in equipment such as fans and household appliances.
For demanding environments, we recommend double-lip contact seals (2RS) made of Nitrile Butadiene Rubber (NBR) or fluoroelastomers (Viton). These contact seals provide positive protection against dust and moisture contamination, retaining lubricant far more effectively than standard non-contact metal shields (ZZ).
We provide full customization, including adjusting radial/axial clearance levels (from C0 to C3/C4), applying specialized high-temperature greases, modifying dimensions, and offering custom branding. Our CAD prototyping process delivers test-ready samples within 7 to 10 days.
Cixi City sits on the bank of Hangzhou Bay, providing direct access to Shanghai Port and Ningbo Port. This strategic location simplifies domestic transit and allows us to offer typical delivery timelines of 7 to 20 days, depending on custom requirements and order volume.
We supply complete material test reports (MTRs) and quality documentation for every shipment. Our traceability system indexes raw material inputs, heat treatment metrics, and physical testing logs to ensure consistent, reliable quality for all VETOR bearings.
