Model 3526 Eccentric Mass Wheel

Overview

The Model 3526 Eccentric Mass Tester is designed to evaluate automotive wheel fatigue without spinning the test part. A stationary moment shaft is attached to the wheel from below with an offset mass spinning around the moment shaft. The spinning offset mass provides a load that transfers through the moment shaft to the test wheel.

Fixtures are utilized to align the wheel and attach the moment shaft. Due to the height of the machine, a work platform is required around the test area. This machine is the newest technology machine for wheel fatigue testing and designed for SAE J328 testing with passenger car and light truck applications.
