Creep bearing NSK successfully expanded the range of size range

 Japanese seiko NSK bearings co., hereinafter referred to as the company expanded at present on the fan motor, pump power to prevent the creep and widespread use of "anti creep ™ bearing" series. This series has the superior creep force, simplifies the maintenance and installation of motor.

NSK according to broaden the size range, as of 2017 is expected to "prevent creep ™ bearing series" annual sales will achieve 1.2 billion Japanese yen.

Used motor bearings due to assembly constraints, using clearance fit between bearing outer ring and motor bearing * 1 is more, the condition of the load bearing rotating * 2, between the bearing and the bearing seat creates a sliding phenomenon called "creep", the sliding wear and tear may shorten the service life of bearing. NSK to prevent the creep phenomenon, launched into the market in 2007 bearing inside diameter size of 45 mm below the phi "anti creep ™ bearing". This series of bearing obtained the general customers the high praise, at the same time the customer wants to in big high output motor can also use more and more is also high, NSK hereby the bearing size will extend to the diameter is 100 mm.

* 1 clearance fit, the bearing and the shaft or housing, with the gap between the status

* 2: rotating load relative to the axis of rotation, the direction times change of radial direction (radius) load

【 features 】

1. The creep force is 2 times more than the ordinary bearing (more) in the company

Optimize the o-rings and outer diameter surface type O ring embedded in the groove size, through the elasticity and repulsion o-rings, keep bearing and bearing parts with enough force, making the creep resistance to 2 times more than the ordinary bearing (more) in the company.

2. Improve the high temperature creep resistance, extend the maintenance cycle of the machine

Using new type O ring material, high temperature environment can reduce the permanent deformation of 80% (compared with raw materials). Due to the size of the o-rings changes little, can maintain stable creep force, so as to extend the maintenance cycle of the machine.

3. Excellent oil resistance, widen the installed when daub grease choice scope of bearing outside diameter

Used the new o-rings materials, can reduce 87% of ester is caused by oil expansion rate (compared with raw materials). Accordingly, when installed bearing outside diameter surface or inner surface bearing daub oil also can be used to heat performance good ester oils, broaden the scope of the grease is optional.
