Bronze Bushings

Overview

Kormax stock a comprehensive range of Metric and Imperial Bronze Bushes (also known as FB and FBM Bronze Bushes). Kormax’s plain bronze bearings, also known as bronze sleeve bushings, are manufactured from continuous cast bronze, conforming to AS1565 grade C83600 (BS1400 LG2). Progressive sizes are available in imperial and metric sizes, however Kormax can also manufacture bronze bushings to your specific size and tolerance requirements. The ready-to-use nature of these bushes allows significant time savings and lower overall cost in a wide variety of applications. Bronze bushings are supplied across New Zealand and Australia.

Metric and imperial sizes (FB / FBM types) are stocked in New Zealand and available on indent in Australia.
