SpeedMax Saw Chain and Guide Bar
Faster. Stronger. Longer Lasting.
Faster
- 19HX chain designed with a taller, more aggressive chamfer chisel cutter to deliver faster cutting speed and improved chip clearance.
- Replaceable Sprocket Nose (RSN) guide bar minimizes time between cuts and is easily replaceable in the field.
- A re-engineered tail contour decreases friction and is less likely to throw chain improving uptime.
Greater Durability
- Oregon’s largest and thickest components designed to improve strength.
- Patented saw chain steel for increased resilience, especially in cold cutting conditions.
- Newly engineered blued cutters provide superior corrosion resistance.
Longer-Lasting
- The SpeedMax XL .404" bar body was developed with a chrome-moly plating for reduced deflection and a wider body for increased chain retention and longevity.
- The re-engineered RSN features a larger, 14-tooth sprocket with high-alloy industrial bearings that reduce the amount of rotations leading to decreased heat build-up extending the life of the bar nose.
LubriTec™ Lubrication System
- Chain tie-strap design keeps oil where it’s needed – on the saw chain.
- Guide bar lubrication channel increases contact between chain drive links and oil, significantly reducing oil waste.
Enhanced Precision
- Accurate part matching improves performance while reducing wear.
- Meticulously engineered components work together to deliver unparalleled efficiency, performance, and durability.
Fit-Up
- Bar Lengths: 17-44" (42-113cm)
- Recommended: Use .404" rim-type sprockets that were specifically designed as a precise match to Oregon .404" chains.

.404" Rim Sprocket
Precision balanced rim sprocket
Machined from durable solid-billet steel and featuring a raised tooth design, the .404" rim sprocket was engineered as an exact fit for Oregon .404" chains, and thoughtfully designed to reduce chain stretch and debris ejection with tapered side-ports.

- 18/19HX designed to outlast cold cutting conditions with patented saw chain steel.
Enhanced Speed
- 18HX delivers plenty of power and reliable cutting performance with less horsepower output.
- 19HX delivers faster, more consistent cuts in all types of wood due to its high-flow, high-power heads and saw motors. Best used with high horsepower output machines.
LubriTec™ Lubrication System
- 18/19HX feature chain tie-straps designed to keep oil where it’s needed – on the saw chain.
Horsepower Parameters
- 18HX operates best with 5/65 HP (min/max) power output.
- 19HX operates best with 20/65 HP (min/max) power output.
Chain Speed Parameters
- 18/19HX operates best at 3000/8000 (ft/min) power output. Recommended: 8000 ft/min.
