Boring diameters

Our onsite line boring scopes for in-line boring are

  1. Internal Bore – 22 mm to 800 mm x 3.5 metres long
  2. External Bore – 40 mm to 200 mm x 50 mm long.

With new spherical bearings, pins, bushings, and pivot points that are precision bored for a perfect fit, your equipment and bore repairs will work like it was brand new again.

Our portable line boring services allow us to provide onsite repairs of worn or over-sized bores on loaders, excavators, and all types of heavy construction equipment.

It is common for a mechanical bore to become worn in this field. They become egg-shaped or worn to the point where they no longer function as intended. This happens due to high cyclic load, old age, lack of grease and so on.

Our fully equipped machine shop can quickly manufacture or repair any damaged or broken parts, such as pins, bushings, and linkages in support of our on-site service.

On-site line boring is just one area of expertise that Calvert Site Services excel.
