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 restrictions
All Chiksan swivel joints have a streamline bore design to minimize turbulence and
pressure drop throughout the stated pressure range.
Simple maintenance
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.
Wide selection
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.
