Do you know koyo bearing interchange?

Koyo bearing interchange of sliding bearing, a bearing that works under sliding friction. Koyo bearing interchange of sliding bearing, smooth, reliable, noise-free koyo bearing interchange of sliding bearing. Under liquid lubrication conditions, the sliding surface is separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has certain The ability to absorb vibration. However, the starting friction resistance is large. The part of the shaft that is supported by the bearing is called the journal, and the part that matches the journal is called the bearing. The layer of friction reducing material cast on its inner surface in order to improve the frictional properties of the surface of the bearing pad is referred to as a bearing lining. The materials of the bearing bush and bearing bushing are collectively referred to as Koyo bearing interchange of sliding bearing materials. Commonly used koyo bearing interchange of sliding bearing materials are bearing alloys (also known as babbitt or white alloy), wear-resistant cast iron, copper-based and aluminum-based alloys, powder metallurgy materials, plastics, rubber, hardwood and carbon-graphite, polytetrafluoroethylene Ethylene (PTFE), modified polyoxymethylene (POM), and the like. Koyo bearing interchange of sliding bearing applications are generally used under low speed and heavy load conditions, or are difficult to maintain and fill lubricants.koyo bearing interchange

A precision mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss, is called koyo bearing interchange of rolling bearing. The koyo bearing interchange of the rolling bearing is generally composed of an outer ring, an inner ring, a rolling body and a cage. The inner ring is matched with the shaft and rotates together with the shaft, and the outer ring acts to cooperate with the bearing seat to support the rolling element, and the rolling body is evenly distributed between the inner ring and the outer ring by means of the cage. The shape size and quantity directly affect the use performance and life of the koyo bearing interchange of the rolling bearing. The cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements to rotate to provide lubrication.koyo bearing
 
Koyo bearing interchange of rollingbearing is easy to use and maintain, reliable in operation, good in starting performance, and high in carrying capacity at medium speed. With koyo bearing interchange of the rolling bearing have large radial dimensions, poor damping capacity, low life at high speeds and high sound. The eccentric bearing (mainly subjected to radial force) in the rolling bearing is usually composed of an inner ring, an outer ring, a rolling element and a rolling element cage 4 portion. The inner ring is tightly fitted over the journal and rotates with the shaft, and the outer ring is mounted in the bearing housing bore. A raceway is formed on the outer circumference of the inner ring and the inner circumference of the outer ring. When the inner and outer rings are relatively rotated, the rolling elements roll on the raceways of the inner and outer rings, which are separated by the cage to avoid mutual friction. The koyo bearing interchange of thrust bearing is divided into two parts: a tight ring and a live ring. The tight ring and the sleeve are tight, and the ring is supported on the bearing housing. Ferrules and rolling elements are usually made of koyo bearing interchange of the rolling bearing steel with high strength and good wear resistance. The surface hardness after quenching should reach HRC60-65. The cage is made of soft steel stamping, and can also be made of copper alloy cloth bakelite or plastic.
