Four Bearings
Using optimized 7 series P4 grade 7002 and 7005 bearings, this series
of bearings has strong hardness and rust resistance, as well as dynamic
balancing technology, the actual runout off of the spindle is close to
0.01 mm, the precision tapered bore is less than 0.005mm, high precision
and durable.

Air Cooling Methods
Using a scientific fan design that can use air circulation to cool the
heat generated by the spindle at high speed, the heat dissipation effect
is better, and the smooth and stable operation of the spindle can be
well improved. At the same time, there is no need for water pumps and
water pipes, and the spindle is air-cooled and dissipated, making it
more convenient to use.
