 FEATURES OF CNC WATER COOLED SPINDLE MOTOR

Zhong Hua Jiang ER11 65mm 0.8KW Water-Cooled Spindle Motor features an intelligent control system and is designed for simple, user-friendly operation, suitable for users of all skill levels.

This is a Φ65mm round water-cooled spindle motor (body length approx. 205–225mm, weight approx. 2.8–3.0kg) with ER11 collet chuck. It delivers 0.8KW of power, supports 0–24,000 RPM speed range (400Hz), and achieves runout less than 0.005mm. Equipped with four upgraded high-precision steel bearings for up to 3× longer lifespan than standard models, it incorporates advanced dynamic balancing technology for minimal noise and vibration.

The water-cooled design provides excellent heat dissipation, significantly lower operating temperatures, and much quieter performance (typically 10–15 dB lower than air-cooled equivalents), making it ideal for long-duration, high-precision engraving and cutting. Perfect for compact CNC routers such as 3018, 3020, 3040, and 6040 models, it excels at processing wood, acrylic, PVC, PCB, and soft metals (aluminum, brass, copper) with superior accuracy and surface finish.

Pre-wired with 4-pin aviation connector, it pairs directly with matching 0.8–1.5KW VFDs (110V/220V) for true plug-and-play speed control. When used with a simple water pump or closed-loop chiller, it delivers professional-grade stability, precision, and durability at an affordable price.
