Large cooling water pumps often have wet bearings. The shafts normally revolve on a water film
Hydrodynamic but at the start-up and shut-down of the pump the friction and wear of the bearing material are
very important for reliable operation.
When the water can contain small particles the resistance against abrasive wear of the bearings becomes important.
The originally fitted bearings on these pumps lasted a half year, the D-glide bearings replacing them have been
in there now for more than three years without problems.
Advantages of the D-Glide solution
- Low wear rates
- Low start-up and shut-down friction
- Good resistance against abrasive wear
