NT3030ELS80TC
Spring Brake - S-Cam
Bendix

This high durability axle brake component features a 30/30 chamber arrangement with a 45 deg clamp angle and a 270 deg air port orientation, delivering consistent braking torque across varied loading conditions. Key dimensional data include a 3 in stroke, 1.48 in stud length, and a 5/8-18 UNF-2A threaded stud with a corresponding 5/8-18 UNF-2A push rod thread. The threaded clevis option (standard) provides flexible mounting on a range of chassis configurations, while service and parking ports are sized at 3/8-18 NPTF and 3/8-18 NPT respectively, facilitating reliable airline connections and straightforward maintenance. Constructed for heavy duty duty cycles, this unit handles temperatures from -40 to 175 F and supports sustained operation up to the maximum 175 F, essential for environments with high ambient temperatures or heavy braking events. The air port position at 270 deg ensures optimal hose routing and clearance in crowded undercarriage spaces. VMRS code 013-004-027 is referenced for standardized maintenance and replacement workflows, and cross references such as ABP N42A 13030C3D and ABP N42A 23030C3D provide viable compatibility checks with equivalent assemblies. Within the 41368 category context, this component is a foundational choice for reliable braking performance on S-Cam spring brake systems and is commonly specified for on-highway and severe-service applications requiring consistent bite and predictable modulation.
