Pulp, Paper, & Roofing Industries
For the past 60 years, RA Heller has excelled in the repair of complex and critical pieces of equipment for the pulp and paper industry. Progressive cavity Pumps as an example.
Our skilled craftsmen have worked with many types of rolls in the pulp and paper manufacturing process, from very large head box rolls to very complex texture rolls.
In our chrome plating shop, we hard chrome plate bearing journals, whether I.D. or O.D., to far exceed their original conditions. This chrome plating process results in a harder, more accurate bearing surface that extends the life of the bearings.

- Dump Truck telescopic cylinders
- Earth Moving hydraulic cylinders
- Hydraulic and pneumatic cylinders
- Hydraulic pump, motor, and valve
- General machine shop work

- Hard chrome plating to restore bearing and seal fits in pump, electric motor, and turbine shafts
- Roll repair and manufacturing face, journal, and head repairs, and texturing
