Cooperation of NSK Bearings I. Collaborative selection of the inner diameter and outer diameter dimensions of the rolling NSK bearing is made according to the standard; NSK bearing inner ring and shaft; the cooperation between the outer ring and the seat hole can only be controlled by the journal. The civil service and the seat hole are officially completed. The cooperation between the inner ring and the shaft of the NSK bearing is selected from the base hole; the cooperation between the outer ring and the seat hole of the NSK bearing is made by the base shaft system.
Correct selection of cooperation; it is necessary to know the practical load conditions of NSK bearings; working temperature and other needs; and in practice it is very difficult. Therefore, most of the conditions are based on the use of fine research to select cooperation.
Second, the weight of the load ferrule and the shaft or the shell between the over-win depends on the load.

First, adhere to the NSK bearing and its surrounding environment. Even if very small dust enters the NSK bearing; it will increase the wear of the NSK bearing; oscillation and noise.
Second, the device should be careful and careful; strong stamping is not allowed; NSK bearings cannot be directly hit; the pressure is not allowed to pass through the rolling body.
Third, the use of the right device; try to use special things; try to avoid the use of cloth and short fibers and the like.
Fourth, to avoid the corrosion and rust of NSK bearings; the best not to take NSK bearings directly by hand; to apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust.

Stainless Steel Sliding Door
Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:
(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;
(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;
(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.
(4)Feet sensor switch applied to avoid contagion;
