3V 5V 8V

Heavy Duty Wedge V-Belts

In construction and properties the narrow belts are similar to the wedge belts in performance, with the only difference being the additional top ridge provided in the narrow belts. These belts are manufactured according to specification RMA-IP 22 and also known as American Wedge Belts. Interchangeability between Narrow & Wedge belts
Acceptable agreement and exchangeability is found between 3V and SPZ as well as between 5V and SPB sections. It is possible to use 3V and 5V section belts in pulleys of SPZ and SPB sections respectively but corollary is not recommended as the top width of the RMA standard pulleys are smaller. Section 8V is however, larger than SPC. Profile SPC may in some cases be used in grooves intended for the 8V profile with some loss of power rating but the opposite is not recommended.

Features:

•  Temperature Range: -18 to +80
•  Maximum recommended belt speed is 30 m/s*
•  Maximum flex rate is f=100 per second
•  Antistatic, Oil and Heat resistant

Applications:

These sections are standardized in USA and Canada therefore it is primarily used in machines exported to/from these countries. 8V section belts are used in heavy duty drives such as stone crushers.

Standards, Dimensions & Product Range:

The standard length designation for Narrow belts is as follows: Belt number / 10 = Outside length in inches. For example: 5V 950 means 950 / 10= 95 inches outside length
