Longer length make the torque bigger,more powerful.

Carefull assembly make the spindle more precisional.

Precision 0.01mm.Coaxial degree less than 0.0025mm.

1. Our Ceramic ball bearings spindle use 4 pcs ceramic ball bearings.

2. Ceramic ball bearings are resistant to high temperatures and low heat , usually 3-5 degrees lower than steel ball bearings during using .

3. Ceramic ball bearings have low friction, low noise and long service life.

4. If you want to use the spindle for aluminum, hard wood, then ceramic ball bearings better than steel ball bearings.

Pumps combione pumping, filtered,oxygen and fountains in one.


Must be used in the water.
Must cut off the electricity once the product works improperly and must maintain it after lifting it from the water.

Diameter: 80mm

Material: Cast Aluminium


Compared with the aluminium profile fixture,the accuracy is much higher , and it is hard to deform.
Inner wall is very smooth, outer walls is sandblasted, relatively fine uniform, but not very smooth,.

Cast aluminium fixture is much heavier than aluminium profile fixture

Product Description

Cast aluminium fixture is high quality aluminium which is casting with a special manufacturing process ,compared with ordinary aluminium ,This product has toughness, strong shock resistance, high hardness and strong antioxidant activity.


Cast aluminium fixture is mainly used for fixation of ancillary products, thereby ensuring the verticality of balancing and ancillary products, ancillary products to improve running accuracy, reduce noise, reduce the accumulated error.

Type: ER20 High accuracy collet

  • Material:65Mn Steel

  • Quantity: 8 pcs (4mm,6mm,8mm,10mm,12mm,1/4(6.35mm),1/8(3.175mm),1/2(12.7mm))

  • Precision ≤ 0.008mm

  • Hardened & Precision ground

  • Widely used in boring, milling, drilling, CNC milling machine wire tapping,engraving spindle machines,machining centers and other processing.

  • Spindle working environment temperature is usually -10 ~ 40 .

  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.

  • Spindle in the preservation and transportation, high-speed grease inside the bearing state will change, customers should be running at low speed for 30 minutes. 3000 rpm and then follow the poor increase, run 20 minutes each. Spindle and the inverter should be working together. The inverter’s specifications and parameter settings need match spindles parameter.

  • Connect the inverter spindle, three-phase inverter power cord should be soldered in the plug 1 (U), 2 (V), 3 (W) feet, 4 feet for the ground. After the power is turned on, to observe whether the spindle rotation axis indicates the direction consistent. If inconsistency should be immediately shut down, replace the inverter and spindle connected two wires of three-phase power supply.

  • It should ensure that before use of water-cooled spindle, the cooling system is working properly. Every day before using the spindle must be running at low speed for 15-20 minutes. Clamping the cutters to spindle, collet nuts ,collets,cutters must be clean enough. Shank inserted into the collet must be greater than 15mm

  • Water cooled spindleMUST be used with water pump. Otherwise the spindle will soon broken.

  • AC spindle motorMUSTuse with inverter. The power of inverter need equal or bigger than the spindle power. Before using,please set up the inverter parameters suitable for spindle. Otherwise the spindle and inverter will broken at once.

  • When you use the spindle,the noise is not same as always,pleaseSTOPthe spindle at once. You may need to replace the spindle bearings.

Before shipping , we did the oil seal to avoid the rust during the long shipment. When you get the spindle, please clearing the oil seal before using. Thank you.

  • 1. Cooling in different ways: water-cooled spindle motor is the use of the water cycle to cool the heat generated after the high-speed rotating spindle, spindle motor with fan-cooled approach to cooling.

  • 2. Noise: Water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very loud.

  • 3. Life aspects: Water-cooled spindle motor pay attention to maintenance, frequently changes the water or the use of industrial water coolers, air-cooled spindle fan mainly by the wind blowing the heat transferred to the heat sink, so as to achieve the cooling effect.

  • 4.If you need use for metal ,hard wood,granite,stone,you can choose metal spindle.Metal spindle much better than wood spindle
