Rotary Unions - Product Brochure
30Pages

A Rotary Union is a device which can be connected to arotating shaft and allow the leakproof transfer of fluids to and from the stationary services. The vital components of Rotary unions are the rotary sealsand the bearing support systems. For the majority of applications the FILTON BELLOWS SEAL is the most efficient. If pressure and/or speed exceed the capability ofthe bellows seal we can provide a FILTON MECHANICAL SEAL. > These products are intended for use on a factory environment. Contact us if the installation issubjected to climatic conditions.Fluids should be free of abrasive...

1.Body.2.Mechanical seal assembly. 3.Ball bearings - life lubricated. 4.Rotary spindle. THIS PART ROTATES WITH THE SHAFT The Rotary (L.C.) Union is intended to light duty applications and is of a simple design using the minimum amount of parts. It is not intended asa unit that can be repaired, though this is possible. For low pressures, temperatures and modest speeds with occasional use it is ideal.For continuous use and easy repairability we recommend the Rotary (R.E.) Union (see page 4), or the Rotary (P.B.) Union (see page 6). TheRotary (L.C.) Union is also useful if there are space...

Union has the same basic design as the Rotary (L.C.) Union but incorporates an oil lubrication reservoir for seal face lubrication. This unit is intended for use on pneumatic applications where the compressed air is dry. This unit may also be advantageous compared to theRotary (L.C.) Union even on lubricated air systems where speeds are high and only occasional pneumatic cycles are in use. Under theseconditions...

The FILTON SYPHON ELBOW is a useful accessory for Rotary(P.B.), (R.E.B), (C.B.) and (C.B.N.) Unions, type S.T. on steam service.The majority of steam cylinders are fitted with a curved syphon tubefor condensate extraction, this can be seen from the typical application drawing shown on page 3.If the diameter to length ratio of the cylinder end bore prevents theuse of a curved syphon tube from being fitted the FILTON SYPHON ELBOW should be used. This allows two pieces of straight pipe to be used, the FlLTON SYPHON ELBOW hinging open to allow fitting through the bore of the cylinder end.It is...

These are manufactured on a specialbasis but can at times be manufactured using the basic bearing housing and main seal from any of the standard Rotary Union range shown in this technical manual.The illustration on the right shows atypical construction using two rotating centre tubes for 3 flow channels. We use Filton Bellows Seals or Filton Mechanical Seals, dependant upon working conditions, between each flow channel.If it is essential to prevent any crosstalkӔ between channels then a double seal having a bleed to atmosphere can be incorporated. > At times it can be useful with multi-flow...
