ISB rotary tables in the SG series are slewing bearings with special spiral outer gear teeth, housed in a steel casing with a worm gear drive system, which engages the bearing gears. The worm drive is supported by two bearings housed in the casing. The open side of the slewing bearing presents a gap between the casing and the outer ring, closed off by a spring energised seal. The worm gear has a square drive socket for connection with a hydraulic motor or electric motor.
ISB rotary tables in the SG series are “All-in-one” systems, in which all the user needs to do is connect the hydraulic motor. They are particularly convenient when structural compactness is required.
