Bearings, CNC Machine Spindle Motor 2.2KW ER20 Water Cooled Engraver Spindle 220V 380V 4 Bearing for CNC Router Wood Engraving,Resistance to Under Heavy Loads(2.2kw 380)

Power: 2.2kwVoltage: 220v 380vCurrent: 8.0A/5.1AFrequency: 400HzSpeed: 24000rpmRunout: less than 0.01mmBearing type: 7005C*2,7002C*1Number of phases: 3Chuck: ER20Grease lubricationThe working environment temperature of the spindle is usually -1040.Before installing the first electric spindle to rotate the spindle head by hand, you should feel flexibility and no blockage. P4 fully sealed angular joint bearings can extend the life of the spindle.The longer the length, the greater the torque and the greater the power.Careful assembly makes the spindle more precise.The accuracy is 0.01mm, and the coaxial cable is less than 0.0025mm1. Our main shaft uses 4 bearings.2. Bearings are resistant to high temperature and low heat3. The ball bearing has low friction, low noise and long service life.

• Middle body diameter: Φ80mm; Cooling method: water cooling
• Speed regulation mode: change the spindle speed through the three-phase output inverter and adjust the frequency of the inverter.
• Power interface: 4 pin waterproof aviation plug is optional.
• The aviation plugs marked "1", "2", "3", "4", "1", "2", "3" are connected to the inverter (U, V, W), and the 4 connected to the inverter will Ground the equipment.
• Main purpose: used for wood, bamboo, ordinary PCB, PVC, PMMA, plastic, bamboo, two-color board (ABS) and other non-metallic carvings.
