What is ECM processing of bearing ring raceway?
Q: What is ECM processing of bearing ring raceway? A: to use electrochemical mechanical improve the productivity and roughness ultra-finished products. The mechanism is: first, a thin oxide film (passivation film) formed on surface part by anode dissolution, then workpiece mechanically scraped activated suitable abrasive tool. During scraping process, pressure tool small insufficient cut metal. Therefore, only passivation at microscopic convex points can be off activate area. concave cannot touched action are …

Polishing mechanism of steel balls for bearings.
Q: The polishing mechanism of steel balls for bearings. A: 1. grinding effect the plate. The plate is related to internal metallographic structure and external process conditions during processing.In state use, main structures are martensite, carbide graphite. Martensite both hard brittle phases; while strength hardness graphite close zero, it like a hole in plate,cutting matrix causing stress concentration.When ball moves along groove under certain pressure, relative surface groove. Due effects …

Causes of bearing damage and several aspects that affect bearing life
Bearing means to hold up. As the name suggests, main function of bearing is use a special structure or material install on shaft reduce friction when running. It also helps ensure rotation accuracy and at same time shaft's accuracy. Also plays protective role. Bearing damage in general basically inseparable from following reasons:1. Material fatigue;2. Poor lubrication;3. Pollution;4. Installation problems;5. Improper handling;1. The raceway surface roller are full dentsThe particles cage worn, grease …

Is the bearing as expensive as possible?
When buying bearings, do you doubt that the higher speed of bearing, easier it is to use? The faster more expensive? Is true? We will explain bearing and factors affecting in detail:For each has its own limit speed. mainly limited by temperature rise caused friction heating bearing. exceeds a certain limit, be unable continue rotate due burns, or even jam bearing.Therefore, we are rotating appropriate type according so need select requirements In some applications, other important than Such as low speed, reciprocating swing, …
