Series B117  – Combats intense weights, torque and high stress – ideal for mounting engineered pulleys in demanding applications.

B-LOC B117 in Mining Application
  • Highest bending moment capacity of all internal units
  • Shorter length than other locking assemblies with two tapers
  • Allows reduced hub width in pulley end discs – lower material cost and lower machining cost
  • Allows for use of smaller shafts – lower material cost and more flexible end discs
  • No axial movement during installation

PowerTwist PowerTwist Drive Belting

The long-lasting upgrade to rubber belts – engineered to handle the demands of the harsh environments found in mining and aggregate applications.

PowerTwist Mining Application
  • Easy, fast installation – belts are made to the required length by hand and roll on to the drive without dismantling drive system components
  • Longer belt life – extremely high strength and low elongation under load results in increased belt longevity and durability
  • Reduce inventory – eliminate the need to purchase and inventory numerous belt lengths
  • Harsh environments – highly resistant to abrasive dust and rock particles, water, oils, grease, common industrial solvents, and extreme temperatures of -40°F to +240°F (-40°C to +116°C)
  • Belt Selection – available in Z/10, 3L, A/13, B/17, C/22, and D32 classical profiles (red) and 3V, 5V, SPZ, SPA, and SPB metric wedge profiles (blue) to cover all of your drives
  • No change in set-up – drops right in to standard pulleys
