Type 28 FLW/FLO Flange Mount Steel Safety Chucks 800KG Max Load Shaft 28mm

    The standard safety chuck is simple in structure, practical and easy to install, which provides fast, safe, reliable and simple coupling shaft and disconnection operation for frequent actions such as coupling transmission and disconnection. Moreover, the size of safety chuck transmission part can be designed and manufactured according to different mechanical specifications and characteristics. The whole structure is safe and free from loose rotation. The sliding safety chuck allows the operator to make axial adjustment during machine operation. Adjustment can be carried out by hand wheel (optional), axial support plate to ensure the safety of the crankshaft winding, accurate transmission of torque. THE BIGGEST MODEL IS TYPE 220
