HRB bearing | how to prevent stainless steel fasteners, lock

There is rotational, have HRB bearing ( ) 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. Lock or killed often occurred in stainless steel, aluminum alloy and titanium alloy materials fasteners, the metal alloy is anti-corrosion performance, the surface damage, produce a thin layer of metal surface in the oxide layer to prevent further corrosion. When stainless steel fasteners are locking teeth lines between the pressure and heat will destroy the oxide layer, that occur between the metal thread blocking or shear, gelling of occur then. When this phenomenon continues, will make the stainless steel fasteners completely lock, lock cannot be removed or continue. Usually a series of locking block shear _ _ gelling _ a series of action occurs again a few seconds, so the correct understanding to use this kind of fasteners, to prevent this phenomenon. 1. Correct selection of products before use to determine whether the product mechanical properties can meet the demand of use, such as the tensile strength of the screw and nut and the assurance of load. The length of the screws should choose appropriate, to tighten the nut 1 - Two teeth from the shall prevail. 2. Before use to check the thread is coarse, any scrap iron or dirt, between these things often leads to deadlock. 3. Before use can make lubrication treatment to the fasteners, it is recommended to use butter, molybdenum disulfide, mica, graphite, or talcum powder for lubrication, currently use paraffin processing for lubrication antilock. 4. Pay attention to when using method of use a, screwing in the speed of the power to appropriate, don't too much too fast, as far as possible choose torque wrench or socket wrench, avoid using adjustable wrench or electric wrench. Too fast can make temperature rise sharply and lead to lock. b。 The direction of force application, nut must be perpendicular to the axis of the screw for screwing. 5. Use the washer can effectively prevent locked tight.
