Manufacture of White Metal Bearings

There are many instances where specialist manufactured white metal bearings are required rather than off-the-shelf components. These can include bearings worn out of specification, older plant where replacement bearings are no longer available, extremely specialized bearings, very long lead-times from the OEM, or a standard new bearing not being a cost-effective option.

Alloy Bearings’ capabilities include reverse engineering of existing bearings to produce a spare or replacement bearing. Our qualified personnel have even been known to prepare drawings on-site at a power station during a planned outage!
 

We manufacture to the highest standards.

Due to many decades of practical experience here at Alloy Bearings, our team are also able to make recommendations to update bearings and incorporate current industry “best practice” improvements into the design. An example is removing dovetails which reduces the likelihood of stress cracks, thus extending the life span of the bearing. We have also successfully manufactured bearings with modified designs to increase oil film thickness and reduce temperatures, and others to increase load capacity.

Typically we are able to manufacture bearings more quickly and cost-effectively than the OEM.
