2. Huzhou Factory

In 2021, the deep groove ball bearing factory relocated from Hangzhou to Huzhou. It operate in a 10,000㎡ production facility with a team of 75 employees, focused on the R&D, and manufacturing of high-performance deep groove ball bearings.

Quality Team: 15 quality personnel, including 2 quality engineers, 20% of staff, covering incoming inspection, in-process control and final testing.

CNC Router core bearings are dominated by high-speed spindle rotary bearings. As core precision components, they undertake spindle rotary movement, ensure machining accuracy, rotational stability and service life, and adapt to high-speed operation of spindles under various working conditions.

1. Spindle Rotary Bearings (Core Precision Components)

These bearings mainly bear combined radial and axial loads during high-speed spindle operation and suppress high-speed runout and vibration, which determine the machining accuracy and speed limit of equipment. Precision angular contact ball bearings are the mainstream choice, while standard deep groove ball bearings are applied to low-speed auxiliary structures.

Precision Angular Contact Ball Bearings (Mainstream Standard Configuration): 7002AC, 7004AC, 7005AC, 71904ACD, 71905ACD (P4/P5 precision grade). Suitable for most high-speed CNC spindles, capable of bearing bidirectional axial and radial loads, serving as the core bearings for high-speed finishing machines. The 719 series thin-walled bearings adapt to high-speed and compact spindle structures, while the 700 series features stronger universality with balanced load capacity and speed performance.

Hybrid Ceramic Bearings (High-end Configuration): 7004/7005 hybrid ceramic ball bearings with steel rings and ceramic rolling elements. Featuring low heat generation, high speed, wear resistance and low thermal expansion, they adapt to ultra-high-speed spindles above 18000 r/min, widely used in high-precision mold carving and fine light metal milling equipment.

2. Matching Methods for Angular Contact Spindle Bearings

DB Back-to-Back Matching (Mainstream Standard): The most widely used solution. Two bearings are installed with their large end faces opposite, featuring large support span, high rigidity and excellent anti-overturning moment performance. It effectively suppresses spindle runout during high-speed operation, suitable for all medium and high-speed CNC Router spindles with balanced radial and axial stability. Preload can be finely adjusted via gaskets to eliminate internal clearance during assembly.

DF Face-to-Face Matching: Two bearings are installed with their small end faces opposite, featuring uniform stress and low noise. However, it has weak anti-overturning capacity, only applicable to low-speed and light-load wood carving machines, not for heavy-load and high-speed milling scenarios.

DT Tandem Matching: Multiple bearings are installed in the same direction with greatly enhanced axial load capacity. Suitable for heavy-duty CNC Router spindles for thick material cutting and deep groove carving.

3-set/4-set Combined Matching: Exclusive for high-end precision machines. The combined DB+DT structure achieves high rigidity, high speed and high load resistance simultaneously, meeting the high-precision and high-stability requirements of continuous processing.
