Product Details

EEJA spindle motor Advantages:

1. Positive air pressure inside is applied to seal the products so no foreign materials can find ways to enter the spindle bodies.

2. Water route is designed inside for cooling and no over heat will happen in working.

3.The bearings are from famous brand in Japan or Germany.

4.The steel of shaft and other key components are from Japan.

5.The motor wires are well treated for high property of electrical resistance.

6.All these result in high quality of long life, precision, high speed, low shaft run-out, etc.

7.The whole manufacturing processes have been designed, tried and improved again and again to meet the high precision requirement

like the master shaft diameter in the tolerance of +/-0.001mm.

8. World class equipment is used for manufacturing and testing. Clean room is used for assembly.

9.The team of designing and manufacturing are well educated, trained and have built up their robust experience in their work.
