5C Series Cast Iron QD Sheaves for “C” Belts

5C series five-groove QD bushed sheaves are manufactured for C, CX, banded belts, and CC v-belts; they range from 6.40" to 50.40" in diameter. Depending on the sheave size, they are made to use SF, E, F, or J QD (quick detachable) bushings, which we also stock. Most of our 5C QD sheaves 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.

How to Choose the Right V-Belt Pulleys?

One of the ever-growing and most widely used product types in the power transmission and automotive industries is the V-belt pulley, also known as the "sheave." A V-belt pulley is an attachment that transfers energy between axles with the help of a V-belt. However, to keep this vital pair of devices functioning correctly, one must secure the appropriate V-belt pulley replacement when an older one gets worn down.Learning to measure a V-belt pulley's size and calculate its dimensions are simple tasks; however, correctly identifying a V-belt pulley type can be complex. To do this, you need to know the size, measurements, and type of your V-belt pulley so that the replacement will operate adequately. V-belt pulleys come in various styles and options, including A-section, B-section, C-section, D-section, 3V-section, 5V-section, 8V-section, variable pitch, double groove, and metric pulleys. We stock over 8,000 different V-belt pulleys alone.
