3 Inch Nishimura Type Differential Shaft

Introduction:

The outer diameter of the 3 inch Nishimura slip shaft is Φ75mm, and the maximum expansion diameter is Φ78mm.

1) Applicable to the core (paper tube, aluminum tube, plastic tube or other material composite tube), standard inner diameter Φ76mm;

2) Inner diameter of friction ring Φ45mm

3) Friction ring width 40mm(standard), other width: 30, 35, 40, 45, 50mm,

The standard number of pistons is eight, and can be made into six or twelve depending on the required tension.

The slip ring of 8 pistons is suitable for slitting of packaging film and general film.

The slip ring of 12 pistons is suitable for the slitting of the lithium battery pole piece and diaphragm.

The Nishimura Type Differential Shaft is developed and produced by the Japanese region. The Nishimura slip shaft has a complicated structure and a wide range of accessories, and the requirements for each fitting are also very high, even reaching "u" level. Therefore, many local manufacturers want to produce it, unfortunately this product ended in failure due to its difficulty. The accuracy requirements of three components on Nishimura sliding shaft: Slip shaft expansion block, seal ring and the slip shaft piston are very high, and the biggest difficulty is that several parts need to be combined very well. The effect does not mean that the accuracy of the 1-2 parts is reached, so that the slip axis is ok. It requires the precision of each component to be very high, and it can achieve harmony after assembly. Therefore, in addition to the accuracy of the accessories, it requires long-term experience to complete this product. The Nishimura type slip shaft is mainly used under low tension conditions. For example, the lithium battery industry needs to use this slip shaft product. Any other friction shaft products can not meet its requirements. It can be said in lithium battery industry,the Nishimura differential shaft has become synonymous,companies that make lithium battery products must use the Nishimura slip shaft.
