We have an extensive inventory of replacement parts.

Maintenance & Repair

In North American mills, the average roll is more than 20 years old – this is why roll repair and reconditioning is a large part of what we do. Many times when paper makers encounter roll problems they just learn to deal with it – Fertilla can re-engineer and upgrade your rolls to improve their design, performance and productivity.

Suction Rolls

Fertilla can repair or replace any OEM suction roll. Efficient suction rolls are essential to production.

The work will be inclusive, but not necessarily restricted to the following:
  1. Visual inspection of roll exterior upon receipt for signs of damage.
  2. Disassembly of front head and suction box from roll shell. (Note: Rear head is only removed if required to gain access to internal bearing or with customer’s approval.)
  3. Fully disassemble front (tending) end head and bearing assembly.
  4. Fully disassemble rear (drive) end bearing assembly.
  5. Fully disassemble internal bearing assembly.
  6. All bearings are visually inspected. A verbal report of the condition of the bearings is provided to customer following inspection.
  7. All components disassembled are cleaned either by hand or high pressure system.
  8. Roll shells are pressure washed and dimensionally inspected on ID. After cleaning, holes will be visually inspected as to percentage of plugged holes. Note: Pressure washing of shell will not assure holes to be unplugged.
  9. Dimensionally inspect all journal and bearing housing fits for wear and condition.
  10. Front head and rear, if disassembled, will be measured and recorded for proper interference to shell.
  11. Head studs are visually inspected and checked for proper torque. Head studs will be retorqued, if required.
  12. Head stud nuts are replaced as required.
  13. All air and lube lines will be purged and checked for leaks.
  14. Check rotational worm gear and helical gear.
  15. Repair cracks in shower brackets.
  16. After roll is disassembled, cleaned and inspected, if any needed repairs are found, they will be detailed out, including estimated costs, for customer’s approval prior to work being performed.
  17. Replace following items with customer-supplied parts:

    1. Bearings and seals
    2. Bearing locknuts and washers
    3. Air load tubes and/or springs
    4. Seal strips and end deckles
    5. Shim packs
      Note: If customer directs, Fertilla will provide any or all of these items at an additional cost.
  18. Reassemble roll completely.
  19. Paint all non-paper contact external surfaces of assembled roll.
  20. A detailed written report consisting of all inspection reports (dimensional, bearing, etc.), repairs performed, any critical photographs, invoice breakdowns, grind and balance reports will be provided at a later date.
Additional Suction Roll Services:
  • Complete inspection by a Coldwater Seals Technician to provide the necessary data for the custom manufacturing of cold water Seals, End Deckles and Air Load Tubes.
  • Non-Destructive Testing of shells
  • Drill cleaning of plugged holes
  • Precision roll grinding
  • After grinding of brass or stainless steel roll face, remove front head and box and pressure wash shell and box to remove grinding residue to prevent damage to seal strips and load tubes.
  • Roll balancing
  • Bearing cleaning and inspections by professional bearing representatives

Non-Destructive (NDT)

Fertilla offers a comprehensive range of inspections, including non-destructive testing (NDT). NDT can assess equipment condition without causing any damage. This type of inspection helps our customers make informed decisions based on the condition of their equipment. NDT is a valuable technique that can save our customers money and time in product evaluation, troubleshooting, and research. We accept nothing less than 100 percent accuracy, and we stand behind our services.

Contact Us for more information on our Non-Destructive (NDT) services.

Electroplate

Electroplating is a process that uses electric current to reduce dissolved metal cations to form a coherent metal coating on an electrode. This process is used in a wide variety of industries. Nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object which provides corrosion resistance, wear resistance, or can be used to build up worn or undersized parts for salvage purposes. Fertilla uses this industry preferred process to restore undersized shaft and journal fits. Nickel plating is an excellent option to restore your tapered bearing seat without replacing the entire part.

The ARCSPRAY System

Fertilla offers coatings with ARCSPRAY. ArcSpray process uses two wires electrically charged, one positive ( + ) the other negative ( – ). They are positioned so that when fed together, an arc (ionized path) is formed between the two wires. Compressed air atomizes the molten metal and propels the particles forward at very high velocity. Upon impact, the molten particles fuse to the base metal and flatten out to form a very dense layer. Additional layers can be added to achieve the desired thickness. The coatings can be finished by machining or grinding or used in the as sprayed condition.

ARCSPRAY can be used for the following applications:
  • Carbon steel
  • Cast iron
  • Aluminum
  • Stainless steel
  • Corrosion resistant metals
  • High carbon steel
  • Hard alloy steels
  • Hard stainless steels
The ARCSPRAY is also the most practical method to salvage worn, or mis-machined parts such as:
  • Electric motor shafts
  • Bell housings
  • Pump housings
  • Impellers
  • Pistons
  • Spindles
  • Hydraulic rams
  • Seal areas
  • Molds
  • Patterns
  • Fixtures weldments
  • Rolls
  • Shafts and much more
RE-Machine

ARCSPRAY it, and send it out the door! Unlike flame wire or flame powder coatings, ARCSPRAY coatings are FUSION BONDED to the base metal. This bond means no more flaking or cracking and no more doing it over.
