Precision bearings specially designed for servo motors

Core Strengths 

1. Low volatility and low dust, ensuring clean operation of equipment 

• With TKW new generation low volatility grease +TKW sealing lip  design, the volatility is reduced to half of the industry standard 

• Dust generation is reduced by 90%, encoder contamination and brake  slippage are avoided, and equipment downtime is lowered 

• Compatible with closed servo motors, no additional sealing device  required, facilitating motor miniaturization design 

2 High speed, high rigidity, breaking performance limits 

• Wavy resin cage +FEM optimized design to suppress centrifugal  deformation at 15,000 RPM 

• The deep groove ball series has a dmn value of 1.9 million (40  percent higher than regular products), and the angular contact series has  an axial rigidity increase of 30 percent 

• The ceramic rolling element version has a 40% lower coefficient of  friction and is compatible with ultra-high-speed servo systems 

3 Long life, low torque, reduced overall cost 

• The ME-1 grease has a lifespan of up to 8,000 hours (at 150 ° C),  which is five times that of regular products 

• Optimized sealing lip design reduces operating torque by 10-50% and  lowers motor energy consumption 

• 1 million rapid acceleration and deceleration cycles without  abnormality, service life is extended by more than twice 

4 High precision and low noise, enhanced control accuracy 

• Dimensional accuracy up to P4 grade, rotational accuracy ≤2μm,  ensuring servo motor positioning error ±0.001mm 

• Resin cage + precision raceway grinding, operating noise 3 DB-A  lower than metal cage 

• Precise control of preload reduces vibration interference and  enhances servo system response speed
