Adjustomatic Tensioners, 60-B
The Series 60 Adjusto-Matic has a spring-loaded pivot arm but does not have the screw-type adjustment. It is used in lighter applications (RC 35 to RC 60 chain) where automatic take-up is desired. Since the pivot arm must be adjusted by hand, the mounting location of the tensioner is important.
On both the Series 50 and 60 tensioners, the pivot arm swings 90°from center line in either direction, however, it must be positioned to swing in the direction of the chain (or belt) travel. For reversing drives, the tensioners are used in pairs; one on slack side and one on the tight side.
Available load at idler shaft is the maximum amount of force on the chain developed by the spring loaded arm when deflected 90° to either side of the neutral position.
The basic spring preload is 20% of the total capability. The load curve is a straight line proportion of load to angle of deflection.
Depending on application, please allow a service factor for spring capacity. Springs are shot-peened for longer life.
