21/32" Width, 21/32' Width, 67" Length: Industrial & Scientific. Banded version of "The Energy Saver". Combines the longer life and superior performance of the Gold Ribbon Cog-Belt with the stability of a banded belt. Gold Ribbon’s unique construction (combining the superior flexing of precision molded cogs with the tenacious gripping power of raw edge sidewalls) provides significantly longer belt life. weight or pulley limitation. Where increased horsepower or speed is required or where unusually severe shock loads are encountered. The reinforced band across the top of 2 or more individual V-belts greatly enhances stability by eliminating belt whip and turnover. It prevents the belt from turning over or jumping off the drive. 。 。 。, CARLISLE RBX63-2 Rubber Gold Ribbon Cog-Band Banded Belts, 2 Bands, higher efficiency and horsepower ratings and opportunities to save time. 67' Length: Industrial & Scientific. CARLISLE RBX63-2 Rubber Gold Ribbon Cog-Band Banded Belts, 2 Bands, energy and space. The banded concept was developed for use where multiple belts are impractical because of space.
