Rotary Unions and Arm
Rotating Unions
Rotating unions are a rotary connection, feeding pressure to fixtures while allowing full 360° rotation of the fixture with or without pressure. A machine or independent indexer may do this indexing. Rotating unions allow “live” hydraulic power to be supplied to fixtures during the machining cycle. Single, dual, quad, 6, 8 and 12 path models are available to fit your application. SAE 6 models are required for major fluid Standard Features Single, Dual, Quad, 6, 8 and 12 Flow Path Models
distribution and all remote valve systems. SAE 4 models may be used on double acting systems and small single acting systems where speed of retraction is not critical. mounted or used with standard fittings. Slip Rings are electrical rotary connections which can be operated with some models below. Most units may be either manifold
Solidly bolt into place either the shaft or the housing component of the rotary union; not both. Mount the opposing component using a cableway or similar anti-rotation device to allow for some movement in the event of misalignment.
The leak free design eliminates the need for a drain or vent line required by standard industrial models. This feature also reduces the demand for pressure present in industrial models that can cause pump cycling. All units include internal bearings to increase life under loaded applications. Quad path models are often installed in machine doors to feed two independent dual path models on fixtures, making VektorFlo ® the choice for all of your machine clamping needs. Integral mounting holes and multiple plumbing options make VektorFlo ® designs easier to use than specialized larger industrial model.
