Husqvarna X-Tough 20-Inch RSN Chainsaw Guide Bar — 3/8" Pitch, .058" Gauge, 72 Drive Links

Husqvarna X-Tough 20" RSN is a solid-steel replaceable-sprocket-nose guide bar engineered for heavy-duty cutting on professional Husqvarna chainsaws.

This 20-inch X-Tough guide bar combines a hardened steel body, optimized oiling, and a replaceable sprocket nose to reduce friction, extend service life, and keep maintenance simple. Designed for models such as the 365, 565, 372XP, 390XP, 395XP, 562XP (and Mark II), 572XP, and 592 XP, the bar matches a 3/8" pitch, .058" gauge and 72 drive links for a precise fit and consistent cutting performance. The triple-rivet mount and robust RSN profile make it resilient under heavy use like felling and bucking.

How does the replaceable sprocket nose improve durability and maintenance?

The RSN (Replaceable Sprocket Nose) design moves wear to a replaceable tip and routes load to a high-quality roller bearing with shields. That lowers friction on the rail ends and prevents early wear of the bar body, so routine tip replacements restore performance without replacing the entire bar.

• Replaceable tip reduces full-bar replacement costs
• Roller bearing with protective shields minimizes friction
• Optimized oil hole improves lubrication to the nose
• Triple-rivet mount stabilizes the bar under heavy loads

What makes this bar a fit for professional felling and bucking?

Built from a rigid, hardened steel profile and finished with an RSN shape, the bar resists bending and rail wear during repetitive heavy cuts. The 20" length and 3/8" pitch/.058" gauge specification match professional chainsaw setups for controlled, efficient cutting of medium to large timber.

• Solid steel construction handles demanding cutting cycles
• 20" length balances reach and maneuverability for felling
• Precision manufacturing ensures correct chain-to-bar alignment
• Available spare tip for quick service in the field

Which saw models and chain specs are compatible with this bar?

This Husqvarna X-Tough 20" RSN bar is engineered to fit a range of professional Husqvarna saws and requires a chain with 3/8" pitch, .058" gauge and 72 drive links. Confirm compatibility by matching bar length, pitch, gauge and drive link count with your saw’s specifications before purchase.

• Compatible with Husqvarna models: 365, 565, 372XP, 390XP, 395XP, 562XP, 562XP Mark II, 572XP, 592 XP

How does the bar reduce downtime and simplify upkeep on the job?

The optimized oil hole and hardened rails reduce wear, while the replaceable sprocket nose and roller bearing let you service the most stressed components quickly. In practice this shortens service intervals and reduces the frequency of full-bar replacements.

• Optimized oiling route lowers friction and rail wear
• Replaceable tip allows fast tip swaps without replacing the bar
• Robust RSN shape resists damage from improper use
• Triple-rivet mount increases attachment stability under load
