The octagon mounting head allows for rough adjustment in any direction. Fine adjustments are achieved by movement of the base using the slots. The position of the mounting head in relation to the slots allows for greater adjusting movement than competitive models.
Dalton positioners are made of 60-45-10 ductile iron which insures strength and wear resistance.
Mounting of idlers is achieved by using high strength bolts which secure the inner race of Dalton idler bearings to the positioner.
This unit has the advantages of the Base Pad Tensioner with an attachment for a spring actuated tensioner.
The simplicity of design permits great flexibility in application. The spring loaded arm can be adjusted in 8 secure positions that permit operation in all directions.
The compact construction facilitates mounting where space is at a premium.
This unit provides tensioning and positioning in cases where the mounting surface angle will not permit the use of a base mount tensioner. An excellent use for this tensioner is to allow chain drives to pass over or under obstacles.
The movable spring attachment can be adjusted for flexibility in mountings.
A standard Angular base is used with the spring attachment. The advantages of this base add flexibility to this unit.
The slotted base in this flange mounted tensioner is an important feature of this unit in that it allows for adjustment of the idler's position and can be used to adjust chain tension.
The mounting slots have grooved edges to prevent unwanted movement of the flange mount.
The special Dalton shaft has hardened and ground surfaces to permit the use of needle bearing idler sprockets.
Large pitch idler sprockets are made to fit this shaft so that no set collars or spacers are required.
