Axle Capacity
The beam capacity of the axle model selected. This value may be derated based on the hub face and spring center or outside bracket dimensions, if the recommended dimensions are exceeded. (See G.A.W.R. for other rating information.)

Axle Suspension
A system which provides a method for absorbing shock as well as attachment of axles to a vehicle frame.
A system which provides a method for absorbing shock as well as attachment of axles to a vehicle frame.
Derate
When an axle is built to exceed the recommended overhang dimensions, the rated capacity will be diminished. (See G.A.W.R. for other rating information.)

Double Eye
Leaf springs with eyes formed in each end of the spring.
Leaf springs with eyes formed in each end of the spring.
Double Slipper Springs
Leaf springs that feature a curved surface on both ends of the spring.
Leaf springs that feature a curved surface on both ends of the spring.
Equalizer
A suspension component that allows transfer of a portion of the load on one axle to the adjacent axle(s) when traversing an uneven surface.
A suspension component that allows transfer of a portion of the load on one axle to the adjacent axle(s) when traversing an uneven surface.
Gross Axle Weight Rating (GAWR)
The rated capacity of the vehicle running gear as defined by the lowest rated component in the system. Those components considered are the axle beam, the suspension system, the wheels or rims and the tires.

Hanger Height
The distance (in inches) from the underside of the frame rail (top of hanger) down to the center of the hanger bolt hole.

Leaf Spring
A spring composed of several flat steel strips, bundled together to form a shock absorbing, load carry suspension component.

Leaf Spring Axle
Axles which use leaf springs for the method of suspension.

Load Line
The vertical center line of the tire in the finished axle.
The vertical center line of the tire in the finished axle.
Overslung
Leaf springs mounted on top of the axle.
Leaf springs mounted on top of the axle.
Profile - Bracket
The height of a Torflex mounting bracket, either high or low.
The height of a Torflex mounting bracket, either high or low.
Rubber Capacity
The capacity of a Torflex axle as a result of the amount of rubber used in the assembly. Limits are determined by the axle model selected.

Shackle Link
A suspension component that connects the spring to the trailer frame. The double pivot action of the shackle links accommodates spring articulation and allows the spring to move freely.
A suspension component that connects the spring to the trailer frame. The double pivot action of the shackle links accommodates spring articulation and allows the spring to move freely.
Slipper Springs
Leaf springs that feature an eye formed at the front end and a curved surface on the rear end. The rear end of the spring bears upward against a wear resistant surface in the equalizer and/or rear hanger.
Leaf springs that feature an eye formed at the front end and a curved surface on the rear end. The rear end of the spring bears upward against a wear resistant surface in the equalizer and/or rear hanger.
Spring Center
The dimension from the center of the leaf spring to the center of the other leaf spring on an axle.
The dimension from the center of the leaf spring to the center of the other leaf spring on an axle.
Spring Hanger
A suspension component attached to the trailer frame to which is bolted either a spring eye, shackle link, or equalizer.
A suspension component attached to the trailer frame to which is bolted either a spring eye, shackle link, or equalizer.
Standard Orientation
The longest vertical surface of the Torflex mounting bracket is facing toward the middle of the axle.
The longest vertical surface of the Torflex mounting bracket is facing toward the middle of the axle.
Start Angle
The angle of the torsion arm relative to the horizontal plane, stated in the unloaded condition. This angle is a factor in determining the frame height.

Tie Plate
A steel plate utilized in conjunction with u-bolts to clamp a leaf spring to an axle.

Top Mount
Used with Torflex axles when the trailer frame is built from "C" channels or "I" beams. The mounting bolts are assembled through the TOP of the bracket and bottom flange of the frame rail.
