Hexadrive Series Model HLA-3 Adjustable Pulleys w/ Hexact Linear Actuation Method - Imperial Timken 68514442900

Описание

Hexact Linear Actuation Method The HLA adjustable pulley can be used in place of the standard “HM” pulley where an external mechanical control is available. Typical control methods include hydraulic cylinder, air cylinder, and lever. The adapter nut located on the end of the HLA pulley will accept a threaded rod or a clevis with cross pins. The actuator linkage must be on the center line of the pulley, but radial freedom is required to relieve loads caused by misalignment of the linkage. Actuation rate (closing the moveable flange) should not exceed 2-1/2 inches per minute. To specify the correct pulley, simply substitute the HLA prefix for the HM. For example, the Model HLA-7 pulley has the same drive characteristics as the Model HM-7 hand wheel-type pulley. Refer to the adjacent chart for dimensional information. A torque arm bracket is NOT required for the HLA drive.
