Portable Line Boring

We are the largest Portable Lineboring company in New Zealand and have a wealth of experience behind us. Our machines have been used in the marine industry, earthmoving, forestry, roading and power stations.

Our skilled operators come to your site and can accurately align and linebore out worn or damaged bearing housings, build up the damage with materials matched to the original and then rebore to size to fit the original bearing or bush.

Earthmoving machinery is one of Active Engineering's specialties. Where the mechanic's breakdown service stops, our back-up is second to none. Our line boring equipment is frequently used to repair joints on Excavators, Loaders, Graders or anything that pivots.

We stock and fit Actibush hardened pins and bushes to get your machine running reliably in the shortest possible time.
