MSD SABER SERIES SHEARS
ATTACHMENT GLOSSARY
Rotation Hydraulic drive assembly allows full 360° continuous rotation of the shear. This option gives greater
Assembly positioning capabilities when processing with the mobile shear.
Saber Tip Bolt-on, two-way indexable piercing tip/wear plate found at the top of the upper jaw.
Shear Hydraulic cylinder that powers the cutting action of the shear. The barrel end of the cylinder attaches to
Cylinder the shear's upper jaw and the rod end attaches to the rear cylinder lugs. The cylinder rod stays
protected from damage inside the shear.
Shear Stick The main body of the shear that includes the lower shear. This weldment must be regularly inspected for
damage.
Slide Screw Adjustable components installed through both sides of the stick. Aligns and supports the upper shear for
a uniform blade gap.
Speed Valve Regenerative hydraulic valve mounted on the cylinder of LaBounty® MSD Saber Series shears that
increases the shear closing speed (cylinder extend function) when the shear is not under a load, thereby
reducing cycle times and increasing effi ciency. Stanley LaBounty uses a spool-type speed valve design for
better durability over cartridge-type regenerative valves.
Swivel Allows continuous hydraulic fl ow to the shear cylinder during rotation of shear without twisting hoses.
Manifold
Thrust Main pivot group component that is located inside the end caps as a wear part for the main shaft.
Washer
Tie Rod Rod that extends through the center of the main pivot group. The tie rod adds lateral support to the main
pivot group.
Throat Area of both the upper and lower jaw near the main pivot where the primary blades are located. The
throat area is the optimum area for shearing material. The shear is most powerful on the primary blades
nearest the pivot point.
Turntable Rotary gear bearing used in rotating shears. It is mounted to the shear stick and is driven by hydraulic
Bearing components in the upper head or mounting bracket. This bearing is sometimes called a slewing ring.
Upper Head Mounting bracket portion of a rotating shear. Attaches to the turntable bearing that attaches to the rear of
the shear stick. The upper head contains the hydraulic manifolds and the swivel manifold.
Upper Shear Movable jaw of the shear that contains cutting blades, the Saber Tip™, and the wear area for the slide
pucks. The shear cylinder articulates the upper shear into the lower shear to perform the cutting action of
the shear.
Wear Parts Consists of the cutting blades, guide blade, cross blade, and Saber Tip™. These parts can be easily
replaced to refresh the System wear areas of the shear jaws. Dramatically increased surface areas on
these wear parts provide better wear and less downtime for maintenance.
