The Original Bearing Manufacturer Is Also The Best For Replacements.

Messinger has provided many bearings for MPS-type coal pulverizers. We have a long history of collaborating with OEMs such as Babcock & Wilcox and Foster Wheeler, and with gear box manufacturers in specifying large main thrust roller bearings for use in their assemblies. This equipment is relied on by power generation facilities all over the world.

Prevent Expensive Downtime with Replacement Bearings for Coal Pulverizer Applications.

Messinger Bearings has extensive experience in the power generation market, specifically with coal-fired power plants. Even with alternative energy sources growing, there is still market demand and a need to support the many coal pulverizer units that are in operation today.

We engineer and manufacture the large thrust roller bearings typically found in the gearboxes of coal pulverizer units at electric utility plants, especially those manufactured by Babcock & Wilcox. Some of these gearboxes require bearings as large as 63” in outer diameter (O.D.). Messinger has specialized in these types of bearings for decades and maintains an extensive library of engineering drawings. Much of this documentation is filed by customer, bearing design, and dimension. Since many of these projects were for OEMs, many plants will have an application where Messinger bearings are still used.

MPS-Type Coal Pulverizers: Available in Different Sizes And Units of Output.
