10B Gripbelt Sheaves (10-Groove Cast Iron Split Taper Pulleys)

10B series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts, ranging from 5.75″ to 38.35″ in diameter. Depending on the pulley size, they are made to use with Q2, R2, or U0 taper bushings, which we also stock. Most of our ten-groove 10B split taper bushed pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.

Description

10B Gripbelt Sheaves (10-Groove Cast Iron Split Taper Pulleys)

We precision-machine our 10B series 10-groove Gripbelt sheaves for heavy-duty industrial power transmission systems requiring maximum torque and high horsepower transfer. Designed for use with A (4L) and B (5L) classical V-belts—as well as AX, BX, AA, and BB profile belts—these 10-groove 10B Gripbelt sheaves feature outside diameters from 5.75″ to 38.35″. Depending on the sheave outer diameter, they pair with standard Q2, R2, or U0 split taper bushings to deliver superior clamping force, precise shaft alignment, and hassle-free maintenance.

Key Features & Engineering Advantages

  • High-Strength Construction: We cast our ten-groove 10B Gripbelt sheaves from Grade 35 high-tensile gray iron to withstand continuous heavy loads and shock impact.
  • Corrosion Protection: We apply a phosphate conversion undercoat and a painted outer coat to prevent rust and surface corrosion.
  • Factory Dynamic Balancing: We dynamically balance every 10B sheave at the factory to eliminate high-speed vibration, preserve smooth drive operation, and extend bearing life.
  • Split Taper Bushing Integration: Paired with double-split tapered bushings (Q2, R2, U0), these sheaves provide a true concentric shaft clamp that reduces keyway wear and simplifies installation.
