Technical Information

The Tech-Roll consists of two basic parts:

  1. The “Shell” or cylindrical drum (body) over which the belt or chain is wrapped.
    The shell is open in one end and has an endplate with a centered shaft in the other end. The shaft in the endplate turns with the shell.
  2. The “power unit” consists of a hydraulic motor rigidly mounted to a shaft and an endplate with a bearing assembly. The endplate turns around the shaft.

The power unit is inserted into the open end of the shell. The splined motor shaft is received in a fixed flange inside the shell and the endplate with the bearing assembly closes the open end of the shell.

The shell will turn around the motor-mounted shaft, which is fixed relative to the rotation of the shell. Hydraulic fluid enters and exits the motor through galleries in the shaft.

To simplify installation, the fixed shaft is supplied with a manifold housed in a standard flange or pillow-block style bearing housing.

The Tech-Roll hydraulic motorized pulley is manufactured in the United States.
