AT A GLANCE
Tamping units are used to tightly pack the irregularly sized stones (or “track ballast”) under railway tracks. This process helps support the track’s structure and improves durability. Most of the vibrating arms found on tamping units use plain bearings.
In this application, bearings are expected to have a service life of at least one season, or roughly nine months, before being replaced – a long time considering the vibration, shock, and harsh weather conditions tamping units face during operation.
Anything short of nine months, however, especially when multiplied across several units, means quickly increasing costs and downtime. HPMB® high precision fiber reinforced composite bearings help ensure optimal performance for the nine months users need – and beyond.
HPMB® high precision fiber-reinforced composite bearings have machinable inner and outer diameters for superior application precision, circularity and cylindricity tolerances. In addition, they offer high precision through easy single-point machining of the bearing liner, on-site prior to installation.
Using HPMB® high precision fiber-reinforced composite bearings in tamping unit applications provides the following benefits:
