Sleeve / Idler Pulley
Precision bearing-mounted idlers for consistent belt routing and wrap angle. Idle/sleeve pulleys from JBMK are fixed-position guides that route the belt around accessories, reducing noise, vibration, and harshness (NVH) in the engine bay. Looking for a spring-loaded automatic tensioner instead? See our dedicated Tensioner Pulleys range.
Performance Engineering Highlights
