Product Description

Product Description

We understand that in the dental and high-precision tooling industries, bearing performance directly impacts tool reliability, patient comfort, and operational efficiency. Huzhou Huachuang specializes in the production of micro bearings for high-tech and precision spindles. Our expertise lies in customizing miniature bearings that push the boundaries of standard manufacturing—if we cannot make it, it is highly unlikely anyone in the Chinese market can.

Our company has a sales company in the United States, which allows for direct purchase and home delivery. Don't worry about tariffs, we've taken care of everything.

Our company has partners in Germany, and we will handle all pre-sales and after-sales issues.

Our Dental Drill Bearings are engineered to meet the extreme demands of dental handpieces and high-speed grinders.

Product Design & Features:

- Material Excellence: 

Rings: Refined stainless steel (AISI 440C) for superior wear resistance and corrosion protection.

Balls: Available in AISI 440C stainless steel or non-metallic ultra-hard ceramic (Si₃N₄) for reduced inertia and longer life.

Cage: High-strength, low-friction materials such as polyimide or phenolic resin (80-120 grade) offering self-lubricating properties.

Precision & Speed: Manufactured to national standards GB/T307 1-2005, achieving precision grades P4, P5, up to P2. Operates reliably at speeds up to 300,000 to 500,000 rpm under 200-250 Kpa air pressure.

Performance Advantages:
Ultra-High Speed: Optimized internal design allows for stable operation at extreme rotational speeds.
Wear & Corrosion Resistance: The use of refined stainless steel and ceramic materials ensures longevity in sterilized, high-moisture environments.
Customization Expertise: As specialists in micro bearings, we can tailor the inner/outer ring dimensions, materials, and lubrication to fit any handpiece model.

Application Scenarios:

Dental air handpieces and surgical tools

High-speed precision grinders and engraving tools

Micro medical devices requiring sterile, high-speed rotation
