Re: Solid Bearings vs. Roller Bearings

So what other mechanical considerations favor the use of all roller bearings?
Bob Chaparro


The main advantage was reduced labor costs (frequent inspection and lubrication) and a statistically smaller
likelihood of derailments due to journal bearing failure. Railroads were reluctant to buy them because of their
higher installation costs and as someone mentioned, the benefits mostly accrued to other railroads. Some
railroads continued to buy plain bearings on new cars until it was finally banned.
