Kinetics SRH Vibration Isolation Hangers consist of free-standing, large diameter, laterally stable steel springs in series with an elastomer-inshear
insert, assembled into a stamped or welded hanger bracket. To assure stability, the spring element has a minimum lateral spring stiffness of 1.0 times
the rated vertical stiffness. Springs are polyester powder coated, with a 1000-hour salt spray rating per ASTM B-117. SRH 1" and 2" hangers feature
Kinetics patented No-Short spring cap. All SRH hangers incorporate a high deflection, color-coded spring element with
load transferplate and a 0.4" (10 mm) deflection elastomeric isolator complete with load transfer plate.
Hangers with properly deflected coils will allow a support rod misalignment through a 30° arc without short-circuiting. Isolation brackets will
carry a 500% overload without failure. SRH 1" and 2" hangers are available in deflections from 1.20" to 2.40" (30 to 61 mm), and in capacities from
12 to 3500 lbs. (5 to 1588 kg). SRH 4" hangers are available in deflections from 4.09" to 4.40" (104 mm to 112 mm), and in capacities from 100 to
3850 lbs. (46 to 1747 kg).
Kinetics SRH hangers are superior to hangers which incorporate only springs, which can transmit noise through the all-metal construction, and hangers
which incorporate only pads, which can transmit low frequency vibration. Kinetics SRH hangers are recommended for the isolation of vibration
produced by suspended mechanical equipment, low-speed suspended fans, pumps, ductwork, piping, etc.
Vibration isolators for suspended equipment with minimum static deflection requirement exceeding 0.4" (10 mm), and where both high and low
frequency vibrations are to be isolated, shall be hangers consisting of a laterally stable spring in series with an elastomer-in-shear insert
complete with load transfer plates and assembled in a stamped or welded steel bracket.
The bracket shall be finished with an polyester powder coating. The manufacturer shall provide independent laboratory testing showing that
the bracket with this finish has endured a minimum of 1,000 hours of exposure to salt spray fog testing per ASTM B117 without signs of corrosion.
The elastomer insert shall be molded from oil-resistant compounds and shall be color coded to indicate load capacity and selected to operate
within its published load range.
The spring element shall have a minimum lateral stiffness of 1.0 times the rated vertical stiffness.
Springs shall be color coded or otherwise identified to indicate load capacity.
The hanger bracket shall be designed to carry a 500% overload without failure and to allow a support rod misalignment through a 30°
arc without metal-to-metal contact or other short circuit.
The 1" and 2" hanger brackets shall incorporate spring caps with indexed steps which correspond to the washer diameter of appropriately sized hanger
rod to keep the rod centered in the spring cap and reduce rod misalignment. The spring caps are protected under U.S. patent number 5,653,426.
Isolation hangers shall be selected by the manufacturer for each specific application to comply with deflection requirements as shown on the
Vibration Isolation Schedule or as indicated on the project documents.
The combination isolation hanger assembly with neoprene insert shall be SRH, as manufactured by Kinetics Noise Control, Inc.
