German NSK bearings, NSK models, NSK prices
NSK bearings are bearings that operate under sliding friction. Plain bearings operate smoothly, reliably, and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear; the oil film also has a certain vibration absorption capacity. However, the starting friction resistance is relatively high. The part of the shaft supported by the bearing is called the journal, and the part mating with the journal is called the bearing bush. The anti-friction material layer cast on the inner surface of the bearing bush to improve its friction properties is called the bearing lining. The materials of the bearing bush and bearing lining are collectively referred to as plain bearing materials.
German NSK coupling NSK model NSK price
NSK couplings transmit motion by welding or bonding a thin-walled corrugated tube (bellows) directly to the two halves of the coupling. This type of coupling features a simple structure, compact dimensions, ease of machining and installation, and high transmission accuracy. It is primarily used in low-power precision machinery and control mechanisms that require compact structures and high transmission accuracy. The coupling consists of two hubs and a thin-walled metal tube, connected by welding or bonding. Although many other materials are available, stainless steel and nickel are the most common materials for the metal tube. Nickel tubes are completed using electrodeposition.
