Main Product :
Angular contact ball bearings
Product line 7014 (this series does not require external forced cooling)
21 steel balls（11.906mm）bearing for 8,000rpm spindles
With self designed PEEK material cage, under the same rigid (preload) condition, the spindle temperature rise is lower than 20% under the condition of limiting speed, and the life is extended by more than two times.
21 steel balls（11.906mm）bearing for 10,000rpm spindles
The spindle not only has higher rigidity (preload), but also lower temperature rise.
7014 small steel ball series— 10,000rpm bearing with 29 balls (dia. 7.938mm)
Lower temperature rise with the same ball diameter According to the different parameters, can meet with the use of 10,000 and 12,000rpm
21 ceramic balls（11.906mm）bearing for 12,000rpm spindles
Technical breakthrough: more load capacity, covering both high-speed cutting and heavy cutting; lower temperature rise, under the conditions of speed limit, the temperature is much lower than 15 ℃, without external forced cooling.
7014 small ceramic ball series— 12,000rpm bearing with 29 balls (dia. 7.938mm)
Lower temperature rise with the same ball diameter
7014 small ceramic ball series— 15,000rpm bearing with 29 balls (dia. 7.938mm)
Lower temperature rise with the same ball diameter
