Synchronous Smooth Hole 5mm H6 pulley: smoothness and silence for your bevel gearboxes
Flat (or smooth) pulleys are the ideal component to manage the return and tensioning of belts without the vibrations typical of idle toothed profiles. This model, with a useful height of 6mm, is specifically designed to integrate into the most popular linear drive systems, ensuring smooth guidance and perfect alignment. With DHM, choose quality mechanical components selected to last and improve the precision of your machine.
What is the Smooth Synchronous Pulley H6?
It is an aluminium transmission element with a smooth outer surface and double retaining flange. Unlike toothed pulleys, this model is designed to run in contact with the flat back of the belt. With a 5mm bore and an internal height optimised for 6mm belts, it acts as a stable support that reduces radial friction and prevents the belt from buckling during rapid changes of direction.
Why choose our smooth H6 pulley?
Manufactured to meet the standards of precision engineering, this pulley offers targeted advantages:
- Anti-Vibration Profile: The absence of teeth on the idler eliminates themicro-vibration(polygonal effect) that can occur when the belt teeth meet an idler pulley, resulting in a more constant movement.
- Maximum Noise Reduction: The polished surface reduces mechanical noise during running, making it perfect for desktop or home office environments.
- Aluminium construction: Lightweight and durable, it guarantees low inertia and effective protection against oxidation.
- Belt Stability: Side flanges are designed to keep the belt perfectly centred, minimising edge wear due to misalignment.
Note on manufacturing tolerances
We work to ensure the highest quality consistency, however, due to possible variations between production batches, actual measurements may differ from those stated on the data sheet by ±2 mm (except inner hole). If your project requires specific dimensions or precise millimetre tolerances, we recommend that you contact us prior to purchase for direct verification of stock measurements.
When to use the Smooth Hole 5mm Pulley?
Due to its compact size and compatibility with most common standards, it is ideal for:
- 3D printers (X- and Y-axes): Perfect for bevel drives NEMA 17, where tenth-of-a-millimetre accuracy is essential.
- Tensioning Systems: As an idler pulley to maintain the correct operating tension without stressing the belt teeth.
- Small CNCs and Lasers: Used in synchronous drive systems to ensure superior smoothness of motion in small spaces.
Package contains: 1 x Ø 5 mm H6 SMOOTH SYNCHRONOUS pulley without teeth
