A roller chain looks deceptively simple from the outside — a series of linked metal plates joined by pins and carrying rollers at regular intervals. In fact, each link pitch contains five distinct engineered components, each with a specific material specification,...

Purchasing managers ordering replacement roller chain for the first time often encounter an unexpected complication: the specification sheet from the equipment manufacturer lists a BS chain number, but the local supplier quotes an ANSI number — and the two appear to...

Every roller chain drive faces the same fundamental challenge: the lubricant that protects the pin-bushing interface must be kept in contact with those surfaces long enough to provide a useful film, while contaminants from the environment must be kept away from the...

Lubrication is the single most important maintenance input for a roller chain drive, and also the one most frequently neglected. In applications where access for re-lubrication is restricted — enclosed machinery, high-temperature environments, food processing lines,...

The 3 percent elongation rule is quoted so frequently in roller chain maintenance literature that it can start to seem like a universal constant — a fixed threshold that applies equally to every chain, every drive, and every industry. It is not. The maximum allowable...

The term “chain stretch” is used loosely in maintenance circles to describe the gradual increase in chain length that occurs with operating hours. Technically, the steel in the link plates does not stretch in the plastic deformation sense — the actual...
