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 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. Most units may be either man i fold mounted or used with standard fittings. Slip Rings are electrical rotary connections which can be operated with some models below.

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 lifeunder loaded applications. Quad path models are often installed in machine doors to feed two in de pen dent 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 in dus tri al model.

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.

Reduce cost and hassle of live hydraulic integration of Vektek pumps or continuously connected PO Check industrial pumps. Use on single or dual pallet machines where pallet travels parallel to spindle axis. Telescoping members promote flexibility during installation. Two hose clamp mounting rails included. All clamps and additional rails can be ordered per your requirements (see below). Rotary union interface eliminates premature rotary union failure by preventing the weight of the arm from applying damaging side loads to the rotary union. Rotary Union Arm designed to attach to all Vektek Hydraulic Rotary Unions. Easily customize interface plate to attach most rotary unions.

Hoses All VektorFlo® hoses are intended to operate up to

5,000 psi working pressure. End fittings have the largest possible orifice to

reduce restrictions and allow devices to work better. Large hoses are typically used to feed entire fixtures,

medium size hoses are for feeding small fixtures or single devices.

Small hoses are to be used to feed single devicesONLY and are to be con nect ed directly back to a manifold unless used on double acting clamps.
