What are the dimensions of a Type C V-belt pulley groove?

[MacCora]

C-type V-belt cross-section dimensions are 22mm in top width and 13.5mm in thickness. The minimum diameter for a standard C-type pulley is 200mm. The groove angle for C-type pulleys is 34 degrees when the pulley diameter ranges from 200mm to 250mm, 36 degrees for 250mm to 315mm, and 38 degrees for diameters exceeding 315mm. Relevant information about V-belts: 1. Classification: V-belts come in two types - special cord structure and rope core structure. Rope core V-belts are easy to manufacture with moderate tensile strength and low cost. Special cord V-belts offer better flexibility, higher strength, and are suitable for high-speed applications. 2. Advantages: Simple structure with low manufacturing and installation precision requirements, easy maintenance. Provides smooth transmission with low noise and vibration damping capabilities.
