Power Transmission Chains

A power transmission chain can be identified by a series of two or more connected mechanical components used to transmit power or materials from one location to another.  There is a wide range of chains that are used, depending on the application, the operating environment and the physical stresses, forces and demands.

Common types of Chain used in power transmission applications include:

  • Roller Chain
  • Heavy Series Roller Chain
  • Pintle Chain
  • Engineered Class Chain
  • Self-Lube Roller Chain
  • Corrosion Resistant Chain
  • Attachment Chain
  • Conveyor Chain
  • Engineered Class Chain
  • Forged Chain
  • Pintle Chain
  • Leaf Chain
  • Riveted Roller Chain
  • Stainless Steel Riveted Roller Chain
  • Double Pitch Roller Chain
  • Hollow Pin Chain
  • Side Bow Chain
  • Leaf Chain
  • Self-Lube Roller Chain
  • Silent Chain

Roller Chain

A roller chain is the most common type of chain and most easily recognized.  The chain on a bicycle is standard roller chain.

Chain Used in Power Transmission Applications
A roller chain is referred to by the pitch and the type of roller.  Standard sizes would include 40 Chain, 60 Chain, and 80 Chain. The numbers are determined by the following:

  • The first number in a roller chain designation will tell you the pitch. It is measured in eighths of an inch.

30 chain would have a pitch of 3/8 of an inch or .375”
80 chain would have a pitch of 8/8 of an inch or 1.000”

  • The second number in the designation describes the chain’s roller

0=Standard construction with a roller
1=Lightweight Construction
2=Oversize Roller

Heavy Series Roller Chain

The heavy series roller chain is manufactured with side bars that are equal to the next size larger chain size and contoured side plates.  These chains have added fatigue resistance suitable for high fatigue applications.

Steel Pintle Chain

The steel pintle chain is ideally suited for a wide range of applications such as salt, sand, and fertilizer spreaders, hay handling and other similar conveying systems.  The open barrel construction minimizes pin surface contact within the barrel, eliminating seizing due to corrosion.  It also eliminates material build up in the barrel and sprocket root for a smoother operation and long life.

Engineered Class Chain

Engineering class chains are typically large in pitch and are designed with higher safety factors and more clearances.  These chains may have specialized attachments, materials, seal, or plating for specific applications and environments.  They are rated by workload and strength.  Most engineering class chains will fit in the following categories.

Drive Chain
Roller Conveyor Chain
Bushed Chain
Welded Chain
Bar and Pin Chain
Barloop Chain
Detachable Link Chain
Plastic Engineering Chain
