Pioneer’s large centrifugal casting machine, with capacity up to 127″ outside diameter & 20 tons
At Pioneer, our substantial arsenal of human talent, experience and state-of-the art equipment is applied to both manufacturing and repair work for customers, many of whom in complex projects require both services.
As a result, at Pioneer the following attributes apply to both manufacturing, service and repair:
- Substantial shared experience among machinists manufacturing and repairing the same size, weight, style of bearings and seals.
- A professional Quality Assurance Department with a “nuclear industry mindset” (form over substance is unacceptable).
- Use of advanced CNC-machine tools.
- Available technical support from our in-house engineering department.
- Our competence to propose “value engineering” design changes or upgrades to reduce costs for customers without risking a decrease in performance or reliability.
- The experience and stability of our team and company that distinguishes us in our industry.
- ISO 9000 registration.
Size:
We manufacture and repair fluid film bearings ranging from outside diameters of a few inches to over 100 inches (254 centimeters).
Weight:
Our overhead crane capacity allows us to handle bearings weighing up to 10,000 pounds (over 4.5 metric tons) for the largest turbines and generators at work in fossil, nuclear and hydroelectric power plants.
Quality Assurance:
Our QA team assures that Pioneer’s work-in-progress, finished products, services and accompanying required documentation are all in compliance with the requirements of customers, Pioneer’s quality assurance program, and any designs and specifications of the engineering department. Our previous three-year ISO registration cycle has been extended to 2025.
Our Production Team:
A touch over 50% of our workforce has 20 or more years with Pioneer. Our production manager and his assistant have been with us for over 43 and 27 years respectively. They are supported by a shop foreman with over 32 years in his position and the leadman in our foundry with over 28 years of tenure with Pioneer.
We have invested in the equipment and
developed methods and processes allowing
our manufacturing and repair teams to perform as efficiently as possible while still complying with the high-quality standards
required by our quality assurance program
and the customers and markets we serve.
For example, we routinely use the expensive tin immersion method of pre-tinning even very large bearings, which requires a large tank and burner system, in contrast to the use of inexpensive gas-fired torches most bearing repair shops employ in repairing large parts. This enables us to heat a bearing shell to the correct temperature faster and to apply the heat evenly. Unlike gas-fired torches, our method eliminates any hot spots that could degrade the quality of the babbitt bond.
