About This Item

This SAE Recommended Practice describes a marking system to distinguish long-stroke from standard stroke for service, parking, and combination air-brake actuators, roto-chambers, and components. Said actuators are used for applying cam and disc-type foundation brakes by slack adjuster means. Rationale for revision: Figure 4 is overly specific (remove Figure 4). Replace the term Readjust with Brake Adjustment Limit in Tables 1A, 1B, and 1C to update obsolete terminology associated with manual slack adjusters. Remove Type 14 from Table 1A and 1B as this size is the only hybrid size (externally the same as a type 16) on the table and not relevant for stroke ratings. Revise standard rated stroke for type 24 from 2.25” to 2.50”. Reduce specifications on trapezoidal clamp tag and call for alternative marking with same information for chambers with clamps.
