for Torsion Bars & Shafts
at Specialty Bar Products Company
Specialty Bar Products Company (SBP) is a national and international supplier of custom machine parts that meet exact customer requirements as well as standards for military performance. With CNC machining, non-machining, and non-destructive testing (NDT) capabilities, SBP provides custom machined shafts such as torsion bars and axle shafts that exceed the demands of the most severe military operations.
part: Torsion Bars, Custom Shafts
materials: 4140 Q&T (quenched and tempered), 4350
specifications: 60” length with machined splined ends
Specialty Bar Products uses CNC technology to turn torsion bars that match close tolerances and meet tight deadlines. Our state-of-the-art CNC turning centers can manufacture torsion bars up to 60” for which our induction hardening machines can provide a high-strength outer case. SBP uses alloy steels such as 4140 or 4350 according to customers’ requirements. This bar stock undergoes heat treatment and oil quenching for hardening, and than undergoes tempering to restore ductility that ensures the torsion bar or custom shaft will not snap or shatter during use.
Specialty Bar Products in Action:
Machining Torsion Bar and Custom Shafts
Modern tanks use road wheels that are independently
sprung and attached to torsion bars via swing arms. Confronted
with the mass of the tank, its relative speed, and the resistance
of the ground and ground obstacles, torsion bars for military
tanks must withstand a considerable amount of torque. Specialty
Bar Products uses machining and non-machining hardening processes
to address the stress and fatigue applied to the torsion bar.
Specialty Bar Products also machines custom shafts and torsion bars for commercial applications. The logging and coal mining industries have both benefited from SBP’s commitment to quality in custom machined bars. The tracked Log Skidder Vehicle has utilized SBP’s products while shuttle cars for underground coal mining have come to Specialty Bar Products Company for axle shafts.
