30000 Worm Gear Drive Heavy Load-Carrying Stage
Parker rotary indexing tables provide accurate rotational positioning with a heavy load-carrying capability. Tables feature an angular contact ball bearing system which is stiffly preloaded to produce precise rotation of the table top. The drive mechanism is a precision worm gear drive which provides precise rotational positioning. An angular readout – graduated in degrees – is provided around the circumference of the table top, while a finer position readout dial, found on the control knob, reads directly in 0.01° increments, with the vernier providing even higher (0.002°) resolution. A thumbscrew lock is included to lock the table at the desired setting. For customer convenience, threaded mounting holes with locking threaded inserts are provided as well as a clearance hole through the center of the table to allow easy access from below. If desired, the table top can easily be removed to permit custom modification. These units can be mounted in any orientation and are compatible with Parker linear tables.
