Full definition
Pulley that redirects the belt to increase the wrap angle on the drive pulley, improving traction force transmission. Installed on the return strand near the head pulley. Typical wrap angle increase: 180° to 200-220°. Manufacturers such as Rema Tip Top and Hytrol offer snub pulleys with rubber or ceramic lagging for better grip. A larger wrap angle significantly reduces belt slip risk, especially during peak load starting conditions.
