Chiaravalli – Tensioners CHT – Catalogue

Purpose
CHT tensioners stabilize belt/chain engagement by providing controlled preload and dynamic damping across temperature and load changes.

Key characteristics

• Spring/elastomer modules with defined stiffness to track elongation and shock.
• Pivoting and linear variants with selectable travel; sealed bearings on idler pulleys.
• Corrosion protection for wet/dusty environments; optional locking features for service.

Integration

• Place on slack span to maximize wrap angle; avoid resonance with span length.
• Size travel to expected elongation (thermal + wear) and set initial deflection accurately.
• Inspect pulley alignment and bearing temperature during early operation.
