Dental Handpiece Bearings Manufacturers

Jiangsu Yinghong Transmission Technology Co., Ltd.

About Us

Jiangsu Yinghong Transmission Technology Co., Ltd. (YHU) was established in 2024 through the joint investment of Dongguan Yinghong, Linqing Boshuo, and Yancheng Jiwei. As China Dental Handpiece Bearings Manufacturers and Custom Dental Handpiece Bearings Factory, we leverage extensive industry experience and strong technical expertise to provide reliable, energy-efficient transmission solutions for customers worldwide.
The company covers more than 70 mu of land and operates nearly 10,000 square meters of manufacturing facilities. As a professional manufacturer of precision special bearings in China, we have introduced advanced Japanese precision manufacturing technology and equipped our facility with automated production lines and high-precision testing equipment. A comprehensive quality management system ensures consistent product quality and reliable performance.
As a National High-Tech Enterprise, Yinghong holds multiple invention and utility model patents and has obtained internationally recognized certifications including IATF 16949, RoHS, CE, and SGS. These certifications enable us to meet diverse customer requirements and provide effective solutions for demanding applications and complex technical challenges.
We specialize in the production of high-precision deep groove ball bearings and custom non-standard bearings under our registered trademark, “YHU”. Our main products include bearing steel bearings, stainless steel bearings, ceramic bearings, and plastic bearings.
YHU bearings are designed to deliver low noise, low vibration, low friction, high precision, great sealing performance, and high-speed operation. They also offer self-lubrication, corrosion resistance, rust resistance, acid and alkali resistance, chemical resistance, electrical insulation, non-magnetic properties, high-temperature resistance, low-temperature adaptability, and long service life, making them suitable for demanding operating environments.
Our bearings and bearing assemblies are widely used in electric motors, power tools, pneumatic tools, robotics, drones, household appliances, precision instruments, semiconductor equipment, medical devices, marine equipment, aerospace applications, financial equipment, textile machinery, fishing equipment, and a wide range of specialized industrial equipment.

Industry Knowledge Extension

Information We Use to Configure Your Solution

A dental handpiece bearing quotation is only as good as the working point behind it. The following inputs let us fix a part number, material grade, preload and lubrication package without a round of assumptions.

Project Input Why We Need It Preferred Format
Handpiece model or interchange reference Establishes position, envelope and existing bearing fit Model code, photo or measurement sheet
Shaft diameter, housing bore and width Defines bearing size, tolerance class and fit Dimensional drawing with tolerances
Operating speed and load direction Sets ball grade, cage, clearance and preload Speed range and load description
Cleaning and sterilization regime Selects ring material, shielding and grease Cycle description and temperature
Noise or vibration limit Determines inspection specification and grading Target value and test method
Annual volume and delivery pattern Plans batch size, tooling and production slot Quantities per year and per call-off

Frequently Asked Questions

Can YHU bearings replace the originals in Japanese, German or UK handpieces?

Our high-speed dental drill ball bearings are compatible with handpieces produced in Japan, Germany and the UK, and our low-speed dental handpiece bearings are produced to replace the bearings of well-known foreign brands. Send the handpiece model, a photo of the bearing position and the shaft and housing dimensions, and we will confirm the matching part or develop a non-standard equivalent.

What rotational speed do your high-speed dental bearings run at?

The high-speed range is built for turbine heads running up to 400,000 rpm. Sustained performance depends on the turbine design, preload, grease quantity and air supply, so we set these values together with the handpiece design rather than quoting the speed alone.

Which material is right for repeated autoclave sterilization?

Stainless steel grades are the normal choice for instruments that are sterilized between every patient. SUS420 and SUS440 are selected where hardness and load capacity dominate, while SUS304 and SUS316 are used when higher corrosion and chemical resistance are required. We confirm the grade against the actual cycle temperature and moisture profile of your process.

Do you supply non-standard sizes and fully custom dental bearings?

Yes. We take on standard and non-standard bearing customization projects based on drawings or samples, covering structure, material and performance parameters. The workflow runs from solution design and prototype production to mass delivery and after-sales technical support, with failure analysis available for returned assemblies.

What quality documentation is available for dental handpiece bearing orders?

Yinghong operates under IATF 16949, RoHS, CE and SGS certification, and SGS test reports are available for the relevant lines. Inspection items such as precision, noise, vibration, sealing, wear resistance and corrosion resistance are agreed per project, and the agreed records ship with the batch.

How quickly can a quotation be prepared?

Quotations are fastest when the working point is complete: handpiece model or interchange reference, shaft and bore dimensions, speed and load, sterilization regime and expected volume. With that information we can confirm the part number, material grade, lubrication package and inspection scope in a single response.
