What's with NSK bearing quality goods

NSK bearings imported in operation after a period of time, will inevitably have a need to maintenance or damage to the replacement, the development of mechanical industry in the early for the popularity of professional knowledge is not enough, insufficient awareness of safety operating rules, the author will talk to you today about bearing knowledge points. We recommended for you to the angular contact ball bearing model have QJ309, QJ210, QJ310, QJ211, QJ311, QJ212, QJ312, QJ213, QJ313, QJ214, QJ314. Bearing can be used in: chuck, electrodialysis equipment, plastic granulator, plasma welding machine, glass equipment, bending machine, tablet press, flame arrester, fertilizer processing equipment, cutting equipment, and other fields. You need to know when to bearing maintenance, mechanical maintenance process, to the bearing code and model of equipment to fully understand the technical indicators, such as information, try to rotate the original model to avoid using the substitution model. In practice, some equipment often replace the bearing, and bearing after the replacement is very likely to burn out, this is usually due to bearing model is different, use alternative bearing, bearing own existence that are a direct result of quality defects. Due to sell on the market of bearing quality and time not neat, there is the phenomenon of shoddy, long-term use of inferior bearing parts, to do long-term mechanical equipment wear and tear, reduces the service life of the equipment. Rotate bearing to avoid mechanical maintenance, long-term inventory of accessories, for the bearing appearance inspection, testing functions, to ensure the quality of the bearing. What is the difference between metric and imperial bearings? Metric is also called the metric system. Units are mm, cm, m, imperial bearing expressed in English unit bearing of appearance size, tolerance, suitable for inch size of the device. Imperial bearings are suitable for all kinds of inch size industrial machine, small rotary machine, etc. 1 inch = 2. 54 cm 1 ft = 12 inches = 0. 3048 meters.
