3/4" Pitch Harvester Bars



Gem harvester bars are made from ballistic grade steel that is precision cut using a water jet process that leaves no heat affected zone nor does it cause mechanical stress to the steel.  Gem manufactures the only bars made from the strongest steel used in the mechanical harvester industry.  This steel gives our customers the advantages of a high degree of spring back and a high degree of bend force resistance.

Gem bars are precision machined through robotic manufacturing and laser probe verified for the most consistent, highest quality.  The bars are designed with wide oil wells for increased lubrication and extended wear life.  The rail grooves are precisely and deeply machined to extend wear life.


The rails on Gem bars are not tempered like other bars.  We start with a stronger material which allows us to significantly reduce the flexing of the rails and prevent the rails from cracking.  When rails are tempered, there becomes different hardness between the rails and the main body of the bar.  By not tempering our rails and having a uniform metal hardness for the entire bar, Gem bars have a longer wear life and consistent strength throughout the bar.

Our bars are completely made in the USA at our Grangeville, ID facility.


Gem Chain Bar was one of the first manufacturers of the 3/8" thick harvester bars, leading the way in developing the current industry standard for 3/4 pitch bars.
  Gem Chain Bar continues to meet the changing needs of today's high output mechanical harvesting machines through:
