TAC Series Ball Screw Bearings

The TAC series ball screw bearings use balls made of special materials, such as ceramic hybrid or high-precision steel balls. After fine grinding, they have extremely high surface finish and outstanding hardness, which can greatly reduce rolling friction and wear, and meet the requirements of high-speed and high-precision operation.

High-performance Ball Configuration：The TAC series ball screw bearings use balls made of special materials, such as ceramic hybrid or high-precision steel balls. After fine grinding, they have extremely high surface finish and outstanding hardness, which can greatly reduce rolling friction and wear, and meet the requirements of high-speed and high-precision operation.
Precision Screw Machining：The screw is forged and processed through multiple complex processes using high-strength alloy steel. The thread accuracy reaches the micrometer level, the tooth profile is perfect, and the surface has undergone special hardening treatment, with super axial load-bearing and transmission capabilities, ensuring stable power transmission.
Optimized Nut Design：The internal structure of the nut is ingenious, with efficient ball circulation channels and precise guiding devices. Cooperating with a high-strength engineering plastic or alloy material cage, it can not only make the balls circulate smoothly but also effectively bear radial forces and maintain system balance.

Ultra-high Precision Operation：With the excellent precision and precise cooperation of each component, the axial clearance is controlled within a very small range, providing extremely high positioning accuracy. It is often used in fields that are extremely demanding in precision, such as precision CNC machine tools and electronic manufacturing equipment, ensuring the ultra-precision quality of machining and production.
High-speed Stable Transmission：The special ball material and optimized design enable it to maintain low vibration and low noise even at high speeds, meeting the stringent requirements of high-speed working conditions such as automated production lines and high-speed cutting machine tools, improving production efficiency.
Long Life and High Reliability：The combination of high-quality materials and exquisite craftsmanship endows it with super anti-fatigue and wear-resistant characteristics, reducing the downtime caused by frequent maintenance and providing a solid guarantee for the long-term stable operation of the equipment, lowering operating costs.

Application

The bearings can be used in the following industries
