Conveyor drive shaft
Application Method
The application was carried out in accordance with Belzona Know-How System Leaflet MPT-2. A split mould was machined to size, and coated with mould release agent. The seat area on the shaft was prepared with an angle grinder, and the mould clamped in place. Then Belzona 1321 was mixed and injected into the mould. When the mould was removed, the cured Belzona material forms a new bearing seat.
Belzona Facts
Belzona materials do not shrink during cure. This type of repair is extremely accurate, yet will carry the weight of this conveyor shaft, which supports a 10-ton counterweight. This Belzona repair was completed in less than 24 hours.
