Gates® Power Transmission Super HC® Molded Notch PowerBand® 3/3VX315 Heavy Duty Molded Notch V-Belt, 3VX Section, 3/8 in W Top, 31-1/2 in L Outside, 21/64 in THK, EPDM
When your power transmission application needs a high horsepower solution but is constrained by drive weight or physical space, the answer is Super HC™ Molded Notch belts. Our proprietary ethylene construction process provides a superior combination of flex and load-carrying capacity, transmitting up to three times the horsepower versus comparably sized belts. Super HC MN V-belts put more power where high speeds, high speed ratios or small pulley diameters are required, offering significant benefits over classical section V-belts.
Sealmaster® gold mounted ball bearings feature a wide outer race insert bearing with land riding metallic retainer. The black oxide treated bearing steel insert features an exclusive lock pin and dimple system providing a direct path for lubrication into the bearing and prevents outer ring rotation within the housing. Shaft lock is achieved by either setscrew or Skwezloc® concentric locking collar. The felt seal with flinger provide a good balance between contaminant entry, GoldPlex® HP grease loss and friction.
