Spring Rubber Barrel 50A Black 3/4in Coil Space

The Spring Rubber Barrel 50A Black 3/4in Coil Space (part number RE-SR250B-0750-50) is a precision elastomer component engineered for applications requiring controlled force absorption, vibration dampening, and spring assistance. This 50-durometer rubber barrel spring delivers consistent performance across mechanical assembly, industrial equipment mounting, and equipment stabilization applications where standard metal springs would transmit excessive vibration or produce noise.

The 2.5-inch barrel diameter combined with the 0.75-inch compressed height provides a compact footprint while maintaining adequate spring force for load-bearing configurations. The 50 durometer rating—measuring rubber hardness on the Shore A scale—indicates a medium-firm compound suitable for repeated compression cycles without permanent deformation or material fatigue. Black rubber composition resists UV degradation and maintains dimensional stability across temperature fluctuations typical in field and indoor operational environments. At 0.41 lbs and measuring 4.5 x 1.38 x 4.5 inches, the component integrates easily into confined spaces where metal alternatives would require structural modification.

Technicians, equipment manufacturers, and maintenance professionals rely on elastomer spring elements to isolate shock loads, reduce operational noise in sensitive environments, and extend serviceable life of connected assemblies. This barrel spring design accommodates both static load bearing and dynamic cycling applications, making it suitable for equipment where metal-on-metal contact must be avoided or where gradual force application is preferred over immediate rigid response. The durable rubber construction withstands repeated compression without losing resilience, a critical factor in applications subjected to frequent impact or sustained pressure cycles.
