Title: Both direction plastic oil rotary damperType: LF-38A1. Suitable for the following products: Home appliance, such as washer, dish-washing and toilet seat.Car ashtray and cup holder. Drawer, sliding door, trash bin and small box of furniture.2.Drawing:  3.Product parameters:Module:1.05Gear number:12Pitch circle:12.6Pressure angle:25°The maximum rotation angle:360°Torque range: 0.5-3Kgf.cmNote 1):Nominal torque is measured value under temperature of 23℃, humidity of 80%, rotation speed of test rack motor of 36r/m after damper rotateds for 5 cycles;     2)Provide cusomized torque by changing viscosity of damper grease;     3) The maximum operating temperature scope of damper: -20℃-70℃4.Material:Shell/Cover:PCAxle core /Gear:POMSealing ring:Silica gelDamping oil:Silicone oil5. Basic principles:The torque made by the damping oil to the rotating parts cohesion effect is the resistance. The value of the resistance is decided by the viscosity and contact area is bigger, the resistance is bigger, and vice versa.6.Speed & temperature Characteristics:7.Resistance and Testing:In the production testing under normal 27.5° C, put the products on the axis rotating in a speed of 36r/min. And the resistance in the 3rd rotate is looked as the standard one. Commonly, the resistance can be adjusted from 100g to 400g.Welcome to contact usWe choose the cheapest & best shipping way for you.We will follow up until you receive goods properly.
