Air Cooled Spindle Motor 2.2KW CNC Spindle Motor 220V Square Air Cooled Spindle Motor ER20 Collet 24000 RPM CNC Spindle 6A Spindle Motor 400 Hz for CNC Router Engraving Milling Machine

Technical Parameters: Spec: φ2.4 x 10.3 inch (diameter: 6.2 cm x length: 26.1 cm); Power: 2.2KW; Voltage: 220V; Current: 7.8A; Collet Size: ER20; Ball Bearing: 4 bearings; Frequency: 400 Hz; Speed: 24000 R/min; Runout off: less than 0.01 mm. Mainly used for engraving machine or used with frequency converter.
ER20 Standard Collet: The collet of the CNC router spindle is quenched with manganese steel, and the runout is less than 0.01mm, which has high precision and is not easy to break the knife, which increases the stability of the working process. Dynamic balance technology can effectively reduce noise during use.
Powerful bearing: The air spindle motor uses imported bearings with high accuracy, precision and durability. Significantly improve the hardness and anti-rust performance.
Low noise and heat dissipation: The dynamic balance technology can effectively reduce the noise during use. The scientifically designed air cooling system has a better heat dissipation effect to ensure smooth operation.
