MIL-PRF-62494D(AT)
3.3.6 Angular velocity. The self-aligning bearing shall not degrade overall performance
below acceptable limits and shall retain its unit integrity when subjected to a radial load of 6000 lb
(2722 kg) and when the inner race is oscillated through a 65 +5 degree angle at a rate of
1 +0.2 cycles per second for 1 hour (see 4.4.6).
3.4 Interface requirements. Each shock absorber shall accommodate the following inputs
and interfaces.
3.4.1 Vehicle system interface. The shock absorber shall be compatible with the mating
vehicle suspension as stated in the contract or order, with minimal loss of performance
(see 4.5.1 and 6.2).
3.4.2 Interchangeability. All shock absorbers shall be interchangeable as to fit, form, and
function with other manufacturer's assemblies having the same military part number (see 4.5.2).
3.5 Support and ownership requirements. Each shock absorber shall possess the
following life cycle ownership characteristics.
3.5.1 Bearing. The self-aligning ball bearing shall be fabricated from materials that are
inherently corrosion resistant or are permanently treated to prevent forms of corrosion and
deterioration which affect the bearing's performance. The balls shall be hardened to
Rockwell C40 minimum (see 4.6.1).
3.5.2 Reliability requirements. The shock absorber shall demonstrate a minimum average
life of 5000 miles (8046 kilometers (km)) during vehicle testing (see 4.6.2).
3.5.3 Reserve tube durability. The reserve tube shall have a minimum yield of
60 000 pounds per square inch (psi) (414 kilopascal (kPa)) and wall thickness to prevent denting
(see 4.6.3).
3.5.4 Dirt shield tube durability. The dirt shield tube shall have a minimum yield of
60 000 psi (414 kPa) and wall thickness to prevent denting (see 4.6.4).
3.5.5 Protective finish and color. Unless otherwise specified, (see 6.2) the shock absorber
shall be cleaned, pretreated and primed in accordance with the manufacturer's standard practice.
Unless otherwise specified, (see 6.2) the topcoat color shall be forest green, Chemical Agent
Resisting Coating (CARC) (see 6.5). Painting shall be accomplished without overspray on the
piston rod surfaces (see 4.6.5).
3.5.6 Identification marking. Identification marking shall include, as a minimum, the
following information permanently marked on the exterior of the shock absorber
(see 4.6.6 and 6.2):
