ULTIMATE STATIC LOAD
The gradually applied load value beyond which structural failure will occur in the ball race housing.
To allow for a good margin of safety we recommend operating loads NO greater than 50% of these values.
1. AXIAL
At 90 Degrees to the centre line of the rod end body and in a direction where the bearing is forced through the enclosed side of the bore in the body. (opposite side to the moulded lettering).
This bearing retention feature ensures the optimum pull out load,
provided the rod end is fitted with the moulded lettering facing away from the fitted assembly or mating part.
Swaged stud versions have lower axial pull-out loads due to the failure of the swage.
2. RADIAL
In line with the center line of the rod end body. This is the direction in which load would normally be transmitted in a typical linkage assembly.
Values shown in brackets apply to the shear strength load of our standard threaded studs, as these precede the radial load of the Rod End.
MAXIMUM CONICAL MOVEMENT
The recommended maximum inclusive misalignment angle that can be tolerated before causing a fouling condition when fitted with our standard threaded stud.
OPERATING TEMPERATURE RANGE
Independent tests indicate an operating temperature range of -40°C to 100°C, although the Polyurethane Bearing Race may degrade prematurely in extreme wear conditions if subjected to constant temperatures in excess of 80°C. Due to variations in environmental conditions, we strongly recommend that tests to evaluate suitability to individual applications be performed.
WEAR / LOAD TESTS
The HM series rod end has passed stringent wear tests with each size range subjected to continuous oscillation through a 20° articulation angle, and with a 9Kg load applied.
On completion of 1,000,000 cycles, all rod ends were fully functional, with no sign of wear present.
The above data is given in good faith and is to be used for general guidance only. We strongly recommend that independent tests should be performed to evaluate suitability to individual applications.
All HM Series Rod Ends are to DIN648 manufacturing standards and are available with inch size bearing bore and UNF thread making them a suitable alternative to SAE J1120 style Rod Ends.
