How to judge the quality of automotive bearings The global call for high-end bearings for new energy vehicles is becoming stronger and stronger. New energy vehicles have greatly reduced their dependence on oil and air pollution. Compared with traditional internal combustion engine vehicles, new energy pure electric vehicles have different forms of energy supply, and huge changes have taken place in both the overall layout of the vehicle and the drive system assembly. Bearings, needle bearings, one-way bearings, one-way needle bearings, solid ring needle bearings Bearings are one of the core parts of new energy pure electric vehicles. The quality of bearings in the domestic market is uneven. How to judge the quality of OVO bearings? Let’s take a look at the judgment method of Karui automotive bearings. https://lettercups.wordpress.com/2020/12/14/photo-transfer-paper-can-usually-be-bought-at-crafts / https://plasticcupsa.tumblr.com/post/637442520830345216/information-regarding-the-contents-can-b e https://openingcup.exblog.jp/28356318/ https://bowcup.blog.hu/2020/12/14/show_that_significant_other_that_you_could_still_find_an_occas ional_delightful_surprise https://printingcup.pixnet.net/blog/post/25204427-get-suggestions-of-relatives-and-friends-and-p repare-to-sithttps://frostedgalss.diarynote.jp/202012141129577404/ https://blog.ulifestyle.com.hk/toothbrushcase/4107336/simply-the-family-room-at-home-there-are-p lenty-of-options-to-pick-from https://toothbrushtube.siterubix.com/this-intriguing-candle-holder-is-worth-adding-to-your-homeor-garden-decor/ http://numberscup.bling.fr/2020/decembre/14/161042/search-for-jewelry-stores-in-your-area-that-h as-engraving-services-for-jewelry.html https://blog.libero.it/wp/cartooncup/2020/12/14/racking-your-brains-for-that-many-gifts/ http://frostedprinted.eblog.hu/one-area-of-business-thats-hugely-important-to-eirflowers-is-wedd ing-work-48296 http://trianglefrisbee.order-buy.com/don-t-try-to-teach http://www.enpitu.ne.jp/usr11/119544/diary.html http://blogs.dotnethell.it/preservationbox/Whether-the-recipient-is-young-or-old-this-is-bound-t o-be-a-hit-in-their-dormitory__90626.aspx http://plastictrash.mee.nu/teach_your_child_to_be_adventurous_and_try_new_things https://stripedisc.podbean.com/e/sweet-sound-coming-from-the-wind-chimes-singing-with-the-breeze -in-their-home/ http://popcornbucket.blog.shinobi.jp/tzaole.com/marketing%20gifts%20will%20most https://plasticfrisbee.reblog.hu/this-is-the-best-way-for-a-peaceful-life-and-compromise-with-ea c How to judge the quality of automotive bearings 1. Is the outer packaging clear Under normal circumstances, the original OVO bearing brand has its own dedicated designers to design the external packaging, and arrange for the production of factories that pass the production conditions, so the packaging is very clear from the lines to the color blocks, and the red background and white characters are beautiful. Carry bearing packaging box. 2.Whether there are turbid oil stains on the surface Since the current domestic anti-rust technology is not particularly ideal, it is easy to leave thick oil stains when the deep groove ball bearing body is rust-proofed, which is very sticky when held in the hand, while the OVO produced by the original Karui factory There are almost no traces of anti-rust oil on the bearing, but a very careful expert said that the Carry bearing smells a kind of smell, it must be the anti-rust oil, but it is not visible. 3. Is the chamfer uniform The so-called deep groove ball bearings, miniature bearings, thin-walled bearings, stainless steel bearings, thrust ball bearings, the chamfer, that is, the intersection of the transverse plane and the vertical plane, counterfeit OVO bearings due to the limitations of production technology, in these corners The treatment of the parts is not perfect. 4. Are OVO bearing laser typing and steel printing clear? On deep groove ball bearings, miniature bearings, thin-walled bearings, stainless steel bearing bodies, OVO brand words, labels, etc. will be laser printed. If the OVO font is very small, remember to buy it, it may be counterfeit Karui bearings. However, the original needle roller bearings, one-way bearings, drawn cup needle roller bearings, full needle bearings, and flat needle roller bearings produced by Carui Bearings all use steel stamping technology, and the OVO bearing steel stamping is performed before heat treatment. Therefore, although the font is small, it is deeply concave and very clear. The fonts of the counterfeit Karui bearings are relatively fuzzy. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand. 5. Is there any noise Hold the inner sleeve of the bearing with your left hand, turn the sleeve with your right hand, and listen for noise. Due to the backward production conditions of most counterfeit Karui bearings and the complete manual workshop operation, it is inevitable that dust and impurities will be mixed in the bearing production and assembly process, which are hidden in the deep groove ball bearings and ball bearings, so they will Abnormal noises, noises. OVO bearings, high standard positioning: adhere to the concept of high quality, high starting point and high quality. Karui Bearing Factory has an advanced precision bearing grinder assembly line, bearing vacuum heat treatment, automatic needle bearing assembly line, high-precision bearing testing equipment, product performance, and quality testing systems that have reached international standards. https://www.vendop.com/vendor/future-internationalgift-co-ltd/ https://www.truejob.com/companies/future-international-gift-co-ltd http://connect.releasewire.com/company/future-internationalgift-co-ltd-203650.htm https://singapore.tech-dir.com/en/companies/212119?utf8=%E2%9C%93&preview_token=tA2xDdNWJXeVbtNXKay L https://www.magcloud.com/user/leafcandles https://www.vendop.com/vendor/ningbo-max-electronic-technology-co-ltd/ https://www.truejob.com/companies/ningbo-max-electronic-technology-co-ltd http://connect.releasewire.com/company/ningbo-max-electronic-technology-co-ltd-203652.htm https://singapore.tech-dir.com/en/companies/212125?utf8=%E2%9C%93&preview_token=bfLfziQVJnzTbSBiZD2A https://www.magcloud.com/user/connectors https://www.vendop.com/vendor/ningbo-jinlun-magnet-technology-co-ltd/ https://www.truejob.com/companies/ningbo-jinlun-magnet-technology-co-ltd http://connect.releasewire.com/company/ningbo-jinlun-magnet-technology-co-ltd-203657.htm https://singapore.tech-dir.com/en/companies/212131?utf8=%E2%9C%93&preview_token=yj4yh36XWwBKsYK1H3 Hp https://www.magcloud.com/user/motormagnet https://www.vendop.com/vendor/zhejiang-urus-tools-coltd/ https://www.truejob.com/companies/zhejiang-urus-tools-co-ltd http://connect.releasewire.com/company/zhejiang-urus-tools-coltd-203665.htm https://singapore.tech-dir.com/en/companies/212137?utf8=%E2%9C%93&preview_token=yxoKUS6DzZrAs8k7np69 https://www.magcloud.com/user/metaldrill
