About Us
A Specialized Bearing Factory, From Melting Shop to Clean Room
Anhui Anheng Bearing Co., Ltd. (registered trademark AHAHB,
export brand ANHRM) is located in Xinxing Industrial Park, Shuihu Town,
Changfeng County, Hefei, Anhui, China. Registered in January 2018 and commissioned in
November of the same year, the plant was designed for an annual capacity of
61.2 million sets of bearings.
We specialize in high-precision, low-noise, long-life deep groove ball bearings for
electric motors and motor-driven equipment. Our branded bearings are widely used in
electric vehicles and e-bikes, motors, elevators, power tools, home appliances,
fitness equipment and office equipment — and are sold across China and exported to
the United States, Germany, Europe and Southeast Asia.
The plant runs dozens of CNC intelligent bearing grinding lines, fully automatic end-face
superfinishing machines and automatic assembly lines. Vacuum heat treatment, automatic
ball loading, and complete washing–drying–greasing–sealing lines ensure
process stability — while roughly 10,000 m² of rooftop photovoltaics
power our production with green energy.
Our quality policy is the “Three Nots”: Accept no defective parts.
Make no defective parts. Pass on no defective parts.

Deep Groove Ball Bearings — 6000 / 6200 / 6300 Series
Our core product line is the deep groove ball bearing, available as
Open (no seal, for highest speed), Z (single metal shield)
and 2RS (double rubber seals, grease-lubricated for life) variants.
All dimensions in mm: d × D × B (bore × outside diameter × width).
The AHAHB bearing family — one production system, sizes 6001 through 6308
The 6000 series is a slim, light bearing for confined spaces. With low friction
torque and refined raceway finishing, it is the first choice for
precision instruments and low-noise electric motors, as well as
household appliances where quiet operation matters.

The 6200 series is the all-round workhorse of the deep groove family — a balanced
combination of load capacity, speed and price. It is the standard choice for
electric motors, automobiles and motorcycles, power transmission
and general machinery.

The 6300 series carries larger balls in a wider section, delivering higher radial
and axial load capacity. It serves heavy-duty applications such as
paper-making machinery, gear reducers and reduction devices, and agricultural
machinery where durability comes first.

Open
No shields or seals — minimal friction and highest limiting speed, lubricated with oil in the housing.
Z / ZZ
Single or double metal shields — keep grease in and coarse dust out, suitable for higher speeds than seals.
2RS
Double contact rubber seals, pre-filled with lithium grease — maintenance-free for the bearing’s life.
