Gates B 87 V-Belt - 87 Inch Effective Length Heavy Duty Industrial Power Transmission Belt

The Gates B 87 Industrial V-Belt is engineered for high-performance power transmission systems, utilizing a robust EPDM or Neoprene synthetic rubber compound that resists heat, oil, and ozone degradation typical of demanding industrial environments. Featuring high-modulus, low-stretch polyester or aramid tensile cords, this belt maintains exceptional length stability throughout its service life, minimizing the need for frequent retensioning and ensuring consistent energy transfer efficiency. The precision-formed cog profile (where applicable, or precision ground sidewalls for standard cross-sections) ensures maximum contact with sheave grooves, reducing slip and enhancing drive uptime. Designed to meet stringent RMA and ISO standards for static conductivity and thermal resistance, the B 87 belt is the reliable choice for critical applications such as compressors, large ventilation systems, heavy-duty pumps, and machining tools. Implementing this high-specification belt minimizes catastrophic failure risk and lowers total cost of ownership by extending maintenance intervals. As a Senior Product Manager, we recommend the B 87 for any operation prioritizing drive reliability and maximizing system throughput under high-load, continuous-run conditions.
