1. Gear and rack structure, smooth operation;2. Double cylinder structure can achieve double output;3. The workbench has high processing precision, easy installation of negative cutting and accurate positioning;4. There is a through hole in the middle of the workbench, and pipes can be piped through this hole;5. There are positioning holes on both sides (10~200) or bottom surface (2~7) of the cylinder body, making it easy to install and use;6. There are two buffering modes available, the adjusting screw fixed buffer and the hydraulic buffer. The maximum buffering energy of the hydraulic buffer is 3 to 5 times that of the adjusting screw fixed buffer, and the buffering effect is better. Note: HRQ2 and 3.7 only have the adjusting screw fixed buffering method, and there is no oil pressure buffering device buffering method. Category: Rotary Cylinder, Brand: Airtac, Series: HRQ
