CCSB Series #3 – Improve Curve Negotiation

The AAR mandated Long Travel side bearings be applied to all new cars starting in 2002. The benefits of long travel side bearings were proven out on the test tracks at TTCI. Long Travel refers to vertical distance between the top cap and housing, which is nominally 5/8’’. Proving double the clearance to Standard Travel side bearings, 5/16’’, Long Travel side bearing allow the truck to enter and exit curves more reliably and safely.
The key to long travel is installing the side bearing at the correct Setup Height. Miner’s online field guide provides guidance on how to install side bearings to ensure optimal performance. https://www.minerent.com/field_guide/...
