SR1-5ZZ 2.38*7.938*3.571 Dental Handpiece Bearing
Product Description:
SR1 - 5ZZ dental handpiece bearing has two covers. It is usually used in pneumatic motors. The double - sided covers endow it with better dust - proof performance, and also enable the lubricating grease to be better retained inside the bearing, thus extending its service life.
Dental handpieces are typically used for tooth polishing and grinding, demanding stable rotation speed from bearings. The SR1-5ZZ bearing, with a regular speed range of 20,000–200,000 RPM, meets the speed requirements of straight handpieces.
Its double-shield design effectively prevents dust ingress, retaining lubricating grease inside to extend the bearing’s service life and ensure long-term stable operation.
Dental implant reduction handpieces need to convert high motor speeds into low speeds suitable for implant procedures while providing high torque.
The SR1-5ZZ bearing plays a role here by ensuring stable and precise speed reduction through its high-precision rotation, assisting dentists in performing implant surgeries smoothly and enhancing implantation success rates.
Product Features:
Dental handpiece bearings combine material innovation, precision manufacturing, and structural optimization to deliver rotation, low noise, Service life exceeds 6 months, with premium models offering 1.5 times longer , strong adaptability, making them a critical component for efficient dental equipment operation.
