Koganei's KSHC Series Linear Orifice Shock Absorbers are specifically designed for cleanroom applications, featuring ultra-low dust emissions and a completely silicone-free construction. These fixed-type shock absorbers achieve JIS/ISO Class 5 cleanliness (FED-STD Class 100 equivalent), with particle generation measured within a 0.1 µm range. A unique particle pocket structure prevents dust scattering, making them essential for contamination-sensitive manufacturing processes. The KSHC Series employs an advanced linear orifice structure for smooth and consistent shock absorption, effectively dampening vibrations and impacts on machinery. This design ensures an extended operational life exceeding 2 million cycles. Available in 9 metric sizes (M4 to M25, 40 models) and 9 inch sizes (10-32 UNF to 1-12 UNF, 36 models), they accommodate diverse impact masses and speeds, typically from 0.1 to 1.0 m/s. Operating efficiently from 0 to 60°C with a deflection angle of 1° or less, these shock absorbers provide precise and dependable shock management in controlled environments.
