Title: Bi-directional rotary damper for auto parts Type: LF-23A1.Superiority :Bi-directional rotary damper can be applied on all kinds of home appliance, consumer electronic products and automobiles, such as tiny damper on TV control panel lid, rotary gear damper on CD drawer, silicone oil damper on cassette player, rotary damper on all control panel covers. Small silicone oil damper are designed to absorb impacts and smoothly decelerate loads to prevent damage.This allows faster cycle rates, increased equipment life,and higher production rates while reducing maintenance expenses.2.Drawing:  3.TECHNICAL DATA:A: Damping torque: 35-85gf.cmB: Damping direction: bidirectionalC: Rotational speed max. 50 rpmD: Lifetime 50,000 cycles (1 cycle = 360° left-hand, 360° right-hand). Even after this time, the dampers still produce over approx. 80 % of their original damping moment. The service life of 50,000 cycles may be significantly higher or lower, depending on the application. Much higher service lives have however been achieved in practice.E:Operating temperature range -20 °C to +70 °C4.Features:♣Rotary damper enable products with a smooth mechanical motion function.♣Silicone oil damper protect delicate electronics and extend the life of product by slowing down the speed to prevent lid and access panel closure damage.♣Plastic small gear damper avoid noise during movement.♣High quality silicone oil sealing by ultrasonic tech, stable torque provided. 5.Our services:♣Professional recommendations on tape choice for customers.♣Free samples available.♣Competitive prices.♣In time delivery.♣Quality assurance. ♣Provide OEM&ODM service6.About us:
