The Class D Single-Column Charpy Impact Tester is equipped with high-precision ball bearings to support smooth and accurate pendulum movement during impact testing.

These bearings are engineered to reduce friction and allow precise rotation of critical moving parts such as the pendulum and striker. The design ensures consistent motion by using a set of small, hardened steel balls positioned between polished inner and outer rings.

This configuration enhances measurement accuracy by minimizing mechanical resistance and eliminating unnecessary variation caused by irregular motion. The result is a stable, repeatable swing path—critical for capturing reliable energy readings during Charpy testing.

The inclusion of precision bearings reflects the Class D tester’s focus on mechanical integrity and testing accuracy, supporting dependable results in research, quality control, and industrial applications.
