Genuine original 
quality assurance
External thread bearing
Large load capacity / Wear resistance / High precision / No noise
Precise and powerful Durable static rotation
HIGH-PRECISION HIGH SPEED LONG SERVICE LIFE LOW NOISE
Buying bearings depends on the craftsmanship
Less noise, lower friction, higher speed, less prone to overheating, and higher bearing load
① Stainless steel screw: high load-bearing capacity/long service life
② High speed: Smooth speed without lagging
③ High quality bearing steel: wear-resistant and durable
Lower noise Higher speed Not prone to overheating
Process Demonstration
01
Metal seal Low frictional resistance, fast heat dissipation High temperature resistance and high rotational speed widely used | 02
Rubber seal Dustproof and liquid resistant substances High mute effect Suitable for harsh environments |
Product Features
