What is the thin rim limit for 28"-36" and 38" wheels?

The thin rim limit for 28"-36" and 38" wheels is indeed considered to be 7/8” or less. This specification is critical for maintaining the structural integrity and function of the wheel. A thin rim that exceeds this limit may compromise the wheel’s ability to support loads effectively, which can lead to safety hazards during operation.

In the context of rail systems, sticking to the 7/8” limit ensures that wheels maintain the necessary strength and durability as they travel over tracks and endure potential stresses.

Understanding the specifications related to thin rims is essential for rail mechanic service workers, as it directly relates to safety standards and operational efficiency. Knowing and adhering to these limits helps in preventing wheel failure and supporting overall railway safety.
