BEARING HOUSINGS
A rugged cast steel Bearing Housing for
Crusher in extremely dusty mining
environment
Product Profile:
Bearing Housings are normally produced against customers
specific requirement after the approval of assembly drawing. Housings are cast in either
of the following material:

However other grades can also be used. The material
composition along with tensile strength is checked with the help of the test bar. If
necessary Radiography is done particularly of the load bearing zone. Furthermore, the
castings are annealed and stress relieved. The required heat treatment charts can be
provided on request.
During machining stages, bore diameter is critically
controlled within the specified dimensions. Apart from this, tolerances are also observed
on the ovality, taper of the bore and the center height of the Bearing Housings. All the
tolerances are in accordance with the International Standards.
Final assembly involves ensuring overall dimensions,
leakage test, stamping of mating components of each assembly, rust preventive coating on
the machined/critical surfaces, red oxide and red paint on the inside non-critical
surfaces and the surface treatment and painting of external surfaces. The housings are
then appropriately packed to avoid transit damage
The company can supply Special Bearing Housings either
according to (reputed Bearing manufacturer's design or) as per customer's drawings. The
company can also supply tailor made bearing housings as per customer's requirement. |
