Fenner Drives has introduced the industry’s first heavy-duty automatic tensioner for multiple belt and chain drives. The T-Max RT4000 series is specifically suited to high speed or heavily loaded industrial belt and chain applications and it incorporates a number of features new to industrial tensioner design. Tension and drive vibration dampening are provided by an alloy steel torsional wrapped spring. This spring is easily reversed, making the RT4000 bi-directional, allowing users to optimize positioning. The stamped steel arm design is offset to direct idler load over supporting bearings, thereby eliminating or reducing the effects of overhung load. Arms are removable and custom lengths can be specified to allow ideal idler positioning for almost any given drive. The housing and base are fabricated from die-cast aluminum. Plus it can be installed with a single mounting bolt.
