CNC Spindle Motor 2.2kW 220V, Air-Cooled ER20

Air cooled CNC spindle motor delivers stable high-speed cutting with reduced heat buildup for cleaner engraving and milling results. Designed for router and engraving machines using an ER20 collet, it combines dynamic balance and four precision bearings to support smooth rotation and consistent accuracy. The air-circulation cooling design helps maintain performance during longer runs, while tight runout control supports fine detail work and reliable tool holding.

Built for makers and shops that need dependable performance from a high-speed spindle, this unit is engineered for accuracy-focused CNC work and repeatable results. The four-bearing construction supports durability under load, while the air-cooled design simplifies setup compared with water-cooling systems. Pair it with a compatible frequency converter (VFD) and your CNC router/engraving machine to dial in speed for different materials and bit sizes.
