Favour of Japanese favour ladder (NTN) development gives so-called world the tapered roller bearing of the smallest internal diameter. Before, the smallest size of tapered roller bearing is internal diameter 9.

4 × external diameter 23 × thick 13mm, if roll the internal diameter of bearing has 5mm only, need to use miniature ball bearing, although its are when negative charge is bigger,put in the problem such as life weak point, rigid inadequacy. Introduce according to favour ladder favour, the internal diameter of the tapered roller bearing of this new development, external diameter, thick have 5 only respectively.

0mm, 17.

0mm, 10mm, weight is 11 grams only, but compare with the ball bearing photograph of dimension close, life but tower above 14 times, and rigid but tower above 5 times, reason applicable at bringing to bear on laden the taller, occasion that after needing inflict to be pressed beforehand, uses, appliance of reducer, medical treatment and miniature are for instance mechanical wait.
