Jiaxing bearing small make up and you can talk about the the bearing cage

There is rotational, have HRB bearing ( ) For bearing cage this topic, we invite our jiaxing bearing engineer today for everyone to do a detailed introduction and guidance, hope everyone can learn. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Cage ( The bearing cage, also called bearing retainer, area called card) , refers to the part of the package all or part of the roll body, and with the movement of the bearing parts, used to isolate rolling body, usually also guide roller and keep it in the bearings. Material: rolling bearing at work, heat and wear caused by sliding friction bearing, especially under the condition of high temperature operation, the effect of inertial centrifugal force increased friction and wear with fever, a bracket will be caused serious burns or fracture, the bearing can work normally. Therefore, request retainers material besides have a certain strength, must also be good thermal conductivity, low friction factor, good abrasion resistance, impact toughness, density is small and linear expansion coefficient and rolling body is close. In addition, punching cage should be subjected to more complex stamping deformation, also requires material has good processing performance. In some very demanding cage above a layer of silver (some would cross a On the condition required) 。 Type: the type of the retainers are: low carbon steel/stainless steel cage, bakelite/plastic ( Nylon) Cage, bronze/brass/aluminium alloy cage, etc. According to the manufacturing form different classification: die casting retainers raw materials for aluminum alloy, brass, poured after the raw materials melting into the die casting machine die mold, a will keep frame forming technology. The casting gate go on lathes. The technological characteristics of this party is: die casting cage ( 1) Maintains a direct die-casting molding, can obtain good geometry and dimensional accuracy, without mechanical processing, high production efficiency. （ 2) Crystal forming technology, metal solidification, precision, good surface quality and wear-resisting. （ 3) High material utilization, reduce the cost. But when the die casting aluminum alloy cage, need big tonnage equipment, mold design and manufacturing complex, easy to make a cage pocket hole strain when die casting. Shock, vibration and speed changing in bearing conditions, the need to further improve the quality of die casting retainers. Mold casting manufacturing cage puts engineering plastic vacuum drying of granular material barrel, a resistance wire heating melt into a liquid state, with the help of a plunger or mobile screw pressurizing, half liquid raw materials from nozzle injection molding into forming mould, after heat preservation, cooling to obtain required cage. The process is characterized by: ( 1) Keep a plastic injection forming, can obtain precise geometry and dimensional accuracy and low surface roughness value, without mechanical processing, high production efficiency. （ 2) Mould and plastic moulds simple shapes, bearing assembly is convenient, easy to realize automation control. （ 3) Plastic cage has good properties such as abrasion resistance, magnetic and low friction. But due to the thermal deformation, aging of plastic and brittle faults, and keep the frame structure and some problems on the plastic injection process, keep the mold casting frame of application is limited. Guide way: according to the condition of different forms of bearing retainer work at home and abroad mainly points three 'inner guidance' 'guide' outside 'guide ( Ball guide) '。 If you are more interested in jiaxing bearing group engineer introduced rust cleaning or have any questions, please click on the website on the right side of the online customer service or call:, you full close jiaxing bearing purchasing consultant company. - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
