When it comes to the base parts that go into the 60 roller chain it's important to understand what each component is and what it does, this knowledge can come in especially handy when it comes to inspecting the chains for routine maintenance.
60 Chain Pin:
The pin is 0.234" in diameter per the ANSI B29.1 spec for 60 chains and has the job of handling a portion of the brunt shock loads and working loads that get transferred from the side plates. When inspecting a current roller chain it is important to notate any cracking, deforming, or pin-roll, as any of these three symptoms can prescribe a reason for chain replacement. 60 Chain Bushing:
Bushings within a roller chain are placed between the pin and roller, their purpose is to assist with facilitating the transfer of energy throughout the chain and to be a "bearing surface" within the roller. We offer our 60 roller chains with optional split or solid bushings, solid bushings provide a superior chain working life versus split. 60 Chain Roller:
The rollers for 60 roller chains are 0.469" in diameter and are always a solid construction within our product range. Their job is to effectively roll within the sprocket tooth-root to facilitate the transmission of energy. When inspecting a chain it is imperative to notate any deformation, cracking, or excessive wear. Depending on the circumstance the roller can reveal sprocket tooth "hooking" which means it's time to replace the sprockets, chain misalignment, and proper tension on the chain. 60 Chain Side-Plates:
Sideplates for ANSI 60 roller chain are 0.093" thick for standard chains and 0.125" thick for heavy-duty 60 chains. They absorb the majority of the working and shock loads put on the chain while in motion. When inspecting a chain it's imperative to notate any cracks, deformation, or excessive wear on the top or bottom of the plate. We offer 60 roller chain with standard side plates, wide-waste side plates, and even straight side plates dependent on the requirements of the application.
