Eccentric Shaft Measurement

Eccentric shafts come in many forms, each tailored to specific applications—making it rare for any two to be exactly alike. They are commonly used variable valve lift systems for ICE engines, in rotary engines, reciprocating pumps, automated machinery, robotics, and textile equipment, often functioning as cam mechanisms to convert rotary motion into precise, controlled movement. Regardless of the application or complexity, every eccentric shaft demands a high level of accuracy, especially in critical sections such as the eccentric lobe, bearing journals, and mounting surfaces. Precision in these areas is essential to ensure reliable performance and long-term durability under dynamic operating conditions. That’s why Adcole gages play a vital role in verifying dimensional integrity and surface quality, helping manufacturers deliver components that meet the highest standards and extend the life of the final product.
