Guaranteed for life against breakage, DROPs solid steel couplings make an excellent choice for joining two shafts together.


Our compression couplings are made from solid steel bar stock on our precise manufacturing equipment. Once they are bored and the bolt work and keyway is in place, they are split, deburred, inspected and ready to ship.  

DROP's Couplings are available in all imperial and metric sizes from steel and stainless steel.



  • Made from solid steel or stainless steel

  • Metric or imperial sizes

  • Guaranteed for life against breakage

  • Metric or imperial sizes

  • Grease grooves in place

  • Requires no additional hardware or install screws

  • Multiple Length through Bores (LTB)

DROP's Drum Teeth have a hardness just below the standard hardness of a conveyor or drum chain ensuring that you get the longest life possible from your Drum Teeth without increasing wear on your chain. This allows your Drums and chains to last longer between maintenance intervals.


Teeth come in all standard lengths and non standard sizes are available. Once worn they can be easily replaced to extend the life of your drum assembly.


  • Made from C1050 steel or stainless. C1050 steel is an AISI standard steel with carbon content around 0.5%.

  • Complete range of widths

  • ​Guaranteed for life against breakage

  • C1050 steel drum teeth can be hardened up to Rockwell C58 to match a wide range of chains.
