MECHANICAL POWER TRANSMISSION

Shafts

SHAFTS

  • Rebuild damaged and scored shafts.
  • Protect exposed areas from chemical/corrosion attack
  • Modify bearing areas

Problem: Worn and damaged shafts are conventionally repaired using a hot process (welding /machining or hot metal spray/machining). Obviously these processes, if not carefully controlled, will cause residual damage to the shaft. They also require the disassembly of the machine, leading to downtime.

Belzona Solution: Belzona 1000 Series Metallic Polymers provide cold repair solutions, which can often be carried out onsite, thus limiting the downtime and lost production costs which are incurred.

Spline drives

SPLINE DRIVES

  • Reform damaged sockets to reduce backlash and play
Keyways

KEYWAYS

  • Repair oversize keyways
  • Modify keyway locations

Problem: Oversize or loose and sloppy keyways can lead to major pieces of machinery having to be completely dismantled for a conventional-type repair.

Belzona Solution: Belzona 1000 Series Metallic Polymers provide a permanent long-term repair, which can be carried out onsite, thus eliminating the expenses usually incurred due to extended down time and lost production.

Hydraulic rams

HYDRAULIC RAMS

  • Repair scores in place without heat
  • Protect exposed surfaces from corrosion pitting
Bearing housings

BEARING HOUSINGS

  • Modify existing bearing seats
  • Rebuild damage bearing locations in place without machining

Belzona Solution: All types of bearing housings can be repaired utilizing the Belzona 1000 Series Metallic Polymers, from oversize housings to complete rebuilds. With Belzona, you can rebuild damaged bearing locations in place without machining

Bearing surfaces

BEARING SURFACES

  • Repair/replace low-friction bearing surfaces
  • Reform ball joint housings

Belzona Solution: All types of bearing housings can be repaired utilizing the Belzona 1000 Series Metallic Polymers, from oversize housings to complete rebuilds.

Water-lubricante bearings

WATER-LUBRICATED BEARINGS

  • Repair cutlass bearings
  • Cast line-shaft bearings

Problem: Water or oil lubricated bushes and cutlass bearings often suffer damage due to shaft misalignment or loss of lubrication. Replacement is the only option.

Belzona Solution: Belzona 1000 and 2000 Series Products provide an economically viable alternative using simple casting and molding techniques to provide successful long-term solutions.

Pin and bush housings

PIN AND BUSH HOUSINGS

  • Realign pins into oversized housings
  • Reseat bushes into damaged locations

Problem: Misaligned or oversize pin and bush housings can be the cause of extensive downtime due to the careful welding and machining techniques which are required for conventional repair.

Belzona Solution: Belzona 1000 Series Metallic Polymers offer a rapid, reliable alternative which will allow the machine to be returned to service in a fraction of the time.

Flanged couplings

FLANGED COUPLINGS

  • Repair elongated coupling bolts/dowel locations
  • Rebuild drive faces.

Problem: Very often coupling bolt holes become elongated.

Belzona Solution: Reform them back to the exact size with Belzona 1000 Series Metallic Polymers.

New coupling bolt bushes can also be custom made using simple molding techniques and the Belzona 2000 Series Elastomers.
