Description
Overview:
This 18" chainsaw chain is a non-genuine replacement for OEM No. 20BPX072E, built for reliable cutting with compatible petrol chainsaws such as the Husqvarna 340 and 550XP. The chain loop is made from durable high‐carbon steel with chrome‐hardened cutters and robust rivets to withstand demanding use. It is specified for an 18 inch (45.7 cm) guide bar, with a .325" (8.25 mm) pitch, .050" (1.3 mm) gauge, and 72 drive links. When matched to a bar and drive sprocket that share these specifications, it provides smooth cutting and consistent feed in softwood and hardwood. Suitable for trade and DIY users, it is a practical, cost‐effective way to restore performance on saws used in landscaping, forestry, and property maintenance.
