rotary union seals
UEA uses rotary seal technology that provides a lubricated polymer blend of material. It is extremely extrusion resistant, non-aggressive to the mating dynamic metal surfaces, offers long term performance, lower cost and has a proven successful track record in demanding field applications for well over a decade.
ENERGIZER
Square ring AN11 70A NBR
Helps cap seal create a positive seal within its groove
U-cup
One on each end of the rotary union prevents external oil leakage
U-Cup seals are wider on one end and are tapered back. The wide end is installed facing toward the inside of the swivel.
cap seal
Good extrusion resistance (without degradation)
Non-aggressive to mating surfaces (won’t create wear path damage)
Side wall notches for increased shifting speed within seal groove
Wide temperature range (-40° F to 200° F)
High precision lathe cut seals of a lubricated polymer blend
OD and ID dynamic styles
wear ring
Acts as a bearing surface to prevent spool and housing from metal to metal contact
Excluder Seal
Acts as a dust and debris seal to shield ingress of outside contaminants
Thrust Washer
Acts as a bearing surface for thrust loads
ROTARY UNION SIZE
UEA can produce a large variety of rotary union sizes to meet various needs and applications. Factors that dictate rotary union size: center through-hole size; a liquid tight cord grip; the number, pressure rating, and size of ports; and 4-Bolt flange ports vs. SAE ORB ports.
Small Rotary Unions
Internal bore diameter: 3“ to 5”
Overall length: 6” to 14”
Number of passages: 2 to 6
medium Rotary Unions
Internal bore diameter: 5“ to 7”
Overall length: 14” to 30”
Number of passages: 6 to 12
large Rotary Unions
Internal bore diameter: 7“ and up
Overall length: 30” and up
Number of passages: 12 and up
media
Nearly any non-flammable media can be sent through a rotary union. Examples include:
