Introduction
Series 249 Rod Swivel Specifications
Force ratings, weights, dimensions, and operating specifications can be found in
the 249 and 249N Swivel Product Specification on the MTS web site
(

8 Spherical washers
(adjustable swivels only) On Series 249 swivels, spherical washers compensate for non-parallel
surfaces within the load path of the swivel eye. Different backlash
adjustment settings may cause the surfaces of the split in the swivel eye
to be non-parallel. The washers ensure this does not compromise
backlash adjustment or damage the clamping bolt.
9 Pin Secures the spherical bearing to the swivel jaw.
10 (Feature) Common eye casting for increased compatibility across product lines.
11 Sensor cavity For force ratings of 160 kN (35 kip) and 340 kN (77 kip) the base end
swivel includes a cavity to contain a Temposonics
® linear-position
sensor. This eliminates the need for a spacer plate, increasing overall
stiffness. The base end also features a cable notch and integrated
Amphenol® connector mounting surface.
12 Pilot bore Piloting increases alignment accuracy.
13 (Feature) Common pin, bearing, retaining ring, and jaw for increased
compatibility across product lines.
14 Accelerometer flat The accelerometer flat provides a consistent landing pad for placement
of diagnostic accelerometer for the purpose of measuring force
distortions or backlash when traveling through zero load conditions in
tension–compression loading cycles.
15 (Feature) Increased section thickness for strength.
