Total fan shaft solution - Engineered to work with less energy |
| |
Using traditional methods to accommodate for fan shaft expansion, it's virtually impossible to reduce the heat generated by the bearings without compromises,
or costly modifications.
|
| |
The problem:
The traditional way to accommodate axial shaft expansion is to allow the non-locating bearing to slide in the housing. But, this still leaves operating speed limitations due to heat and vibration, unless expensive lubrication systems are introduced.
|
| |
The solution:
To enable higher speeds and lower operating temperatures, SKF has introduced
the total fan shaft solution. This consists of a CARB toroidal roller bearing in the
non-locating position, an SKF Explorer spherical roller bearing in the locating position, with each bearing mounted in an SNL plummer block housing.

CASE STUDY |
| |
Refinery saves nearly £94,000 by reducing
fan failures |
| |
A refinery was experiencing an unacceptable number of critical fan
failures. Correcting these failures cost £6,144 each in parts and labour,
plus the enormous cost of lost production.
After an initial assessment to study the causes of failure, BRAMMER recommended the SKF total fan shaft solution, which combined an
upgraded bearing solution mounted in SNL plumber block housings.
