introduction：Deep groove ball bearing imported bearings are mainly used to withstand pure radial load，It can also withstand both radial and axial loads。When it is subjected to pure radial load only，The contact Angle is zero。When the deep groove ball bearing has a large radial clearance，Angular contact bearing performance，Can withstand large axial loads 。The friction coefficient of deep groove ball bearing is very small，The limit speed is also very high， Especially under high speed operating conditions with large axial loads，Deep groove ball bearings have more advantages than thrust ball bearings。

introduction：HUROFast fuse specifications A quick fuse is a kind of fuse，Fast fuses are mainly used for short-circuit protection of semiconductor rectifier elements or rectifier devices。The overload capacity of semiconductor components is very low。It can only withstand a large overload current for a very short time，Therefore, the short-circuit protection is required to have the ability to fuse quickly。The structure of the fast fuse is basically the same as that of the packed closed fuse，But the melt material and shape are different，Its made of silverVMelt with variable cross-section in a deep groove。Not given belowHUROFast fuse specifications if you want to know, you can ask on the Feng Ye mall，There are authoritative experts to answer your questions。 A quick fuse is a kind of fuse，Fast fuses are mainly used for short-circuit protection of semiconductor rectifier elements or rectifier devices。The overload capacity of semiconductor components is very low。It can only withstand a large overload current for a very short tim
