SPA V-Belts
The SPA V-belt is one of the most widely used narrow V-belts in industrial drive technology. Thanks to its standardized design according to DIN 7753, this profile offers a perfect balance between flexibility and power transmission. Where standard classic belts often fall short under higher loads, the SPA V-belt has been specifically developed to transmit more power within a more compact design. At RDM Parts, we supply SPA belts that withstand the heavy demands of continuously running machinery and technical installations.
The superior construction of our SPA belts ensures minimal heat build-up and high resistance to oil and heat. This makes them exceptionally well-suited for a wide range of applications, from heavy-duty fans and compressors to industrial mixing machines and agricultural mechanization. Due to the precise flank grinding, the belt grips the SPA pulley perfectly, resulting in high efficiency and a significant reduction of vibrations within your drivetrain.
Expert tip: Technical characteristics of the SPA profile
The SPA profile is distinguished by a top width of 12.7 mm and a height of 10 mm. As with other narrow V-belts, the sizing of an SPA belt is always expressed in pitch length (Lw, Ld, or Lp). A common mistake is confusing the SPA profile with the classic A-profile (13 mm width). Although they are similar in width, the SPA belt is higher and designed for higher belt speeds and smaller pulley diameters. For optimal service life, we recommend always checking that the pulley grooves are free of wear when replacing, so that the new SPA belt does not bottom out in the groove, which would cause slip and heat.
By choosing a high-quality SPA V-belt from RDM Parts, you choose operational security. Our belts feature high-quality tension cords that minimize stretch, meaning you need to re-tension less often and can extend the maintenance intervals of your machines.
