Trackpads: Improved Trackpad Performance through Columbia's Advanced Alloys and Improved Design

 

Trackpads: Columbia Steel pioneered the use of high strength martensitic steels
for trackpads.

Alloy choice combined with engineered design improvements make Columbia Steel's trackpads reliable and long-lasting.

 

 

 

 

 

 

 

Design of Trackpads.
Columbia product engineers make design improvements which result in stronger trackpads. Columbia's designs offer full support under the roller path to eliminate roller path failures due to collapsing. Additional internal bracing is standard to avoid deformation in the later stages of pad life.

Metallurgy of Trackpads.
Columbia established the use of high strength martensitic steels in trackpads. Our H-series alloys offer numerous benefits, including:


Alloy steel does not require deformation to harden like manganese steel. Alloy steel possesses good hardness from
the very beginning.
High tensile strength virtually eliminates pin eye breakage.
Alloy steel resists stretching.
This reduces the need for track adjustment and holds the proper pitch, extending pad and tumbler life.
H-alloys resist cold-flow, greatly reducing the need to remove metal flow in the roller path.

Contact Columbia Steel today and get the high strength steel alloy advantage for your trackpads.
