Description
Overview:
This 18" (45 cm) chainsaw chain is a non-genuine replacement made from tough, heat-treated steel with chrome-hardened cutting teeth for long service life. Built to replace OEM No. 21BPX072E, it suits many mid-size saws including Husqvarna 340 and 550XP, plus selected Makita and Echo models. The chain uses a .325" (approx. 8.25 mm) pitch and a .058" (1.5 mm) gauge, with 72 drive links to match common 18" (45 cm) guide bars. It delivers clean, efficient cutting for general forestry, landscaping, and firewood jobs. Check your bar markings to confirm pitch, gauge, and drive link count before fitting.
Key Features:
- Length to suit 18" (45 cm) guide bars; 72 drive links for correct bar wrap and tension
- .325" (approx. 8.25 mm) pitch for smooth cutting and good chip clearance
- .058" (1.5 mm) gauge for a strong, stable fit in the bar groove
- Non-Genuine Part: cost-effective alternative to branded OEM chains
- Replaces OEM No. 21BPX072E; often used in place of Oregon 21 series and Stihl Rapid Super where specifications match
- Heat-treated alloy steel with chrome-hardened cutters for durability and edge retention
- Riveted construction for strength under high load and fast chain speed
- Compatible with a wide range of Husqvarna, Makita, and Echo saws fitted with the same bar specs
- Easy to fit and tension using standard chainsaw tools
Typical Applications:
Suitable for felling small to medium trees, snedding and bucking, cutting firewood, storm clearance, and general estate and garden work. Performs well in softwood and seasoned hardwood when kept sharp and correctly tensioned. Ideal for tradespeople, arborists, grounds teams, and DIY users who need reliable, repeatable cutting performance.
