Pressure tight seals protect bearings from line fluid
Chiksan® swivel joints are
equipped with dynamic-seal packing units and bonded, brass
anti-extrusion ring. 6- to 12-inch sizes have stainless steel
anti-extrusion ring. The anti-extrusion ring serves as a retainer
and bearing to reduce friction between the resilient packing material
and the packing chamber as the joint is rotated.
Chiksan® packing units (nitrile
or polyresin) offer a leak-tight dynamic seal. Ball races and
bearings are protected from line fluid throughout the stated pressure
range, including vacuum or suction service to 450° F (maximum
temperature rating for nitrile packing units is 225° F). Thus,
Chiksan® swivel joints can be used on both suction and
pressure lines without requiring a change in packing.
Bearings key to rotation, strength
To ensure long, dependable operation, Chiksan®
ball bearings are matched to loading and service conditions.
Although the size, type and number of bearings vary according to swivel
joint design, most Chiksan® swivel joints have two rows of
bearings and flame-hardened ball races. Aluminum and stainless
steel swivel joints can be equipped with hardened, stainless steel
snap-in ball races.
Smooth, round bore design minimizes flow
All Chiksan® swivel joints have a
streamline bore design to minimize turbulence and pressure drop
throughout the stated pressure range.
Only occasional light greasing with a
hand-held grease gun is required to keep Chiksan® swivel
joints on the job. If packing, bearings, or ball plugs should need
replacing, easy-to-use field repair kits are available.
Chiksan® swivel joints come in a
variety of designs and models. There are materials, sizes, working
pressures, temperature ratings, and end connections to meet virtually
all industrial applications. Eight Chiksan® styles
or configurations are available. These styles can be combined
in an unlimited variety of ways to suit any installation.
