A precision cylindrical journal on an eccentric shaft that converts rotary motion into reciprocating motion in industrial machinery.
The crankpin or eccentric journal is a precisely machined cylindrical surface offset from the main rotational axis of an eccentric shaft or crankshaft. This offset creates an eccentricity that transforms continuous rotary input into controlled linear or oscillating output motion through connecting rods or linkages. In industrial applications, it serves as the critical interface between rotating shafts and reciprocating components in engines, pumps, compressors, and various mechanical systems.

While functionally similar, crankpins typically refer to components in multi-cylinder engines where they connect rods to crankshafts, while eccentric journals are single-offset features on shafts for creating reciprocating motion in various industrial machines.
Eccentricity is measured as the radial distance between the journal center and shaft rotational axis using coordinate measuring machines (CMM) or dial indicators. Control is maintained through precision machining, balancing, and strict tolerance adherence.
Regular lubrication, wear inspection, clearance checks, and balancing verification. High-cycle applications may require periodic re-machining or replacement due to fatigue and wear.
