Harvester Bars - Nose-Replaceable

A solid-steel replaceable sprocket nose harvester bar designed for professional forestry equipment. The 35-inch solid steel bar provides exceptional quality and durability, and the replaceable sprocket nose design extends the life of the bar and chain.

Machined from a single piece of rigid steel, this bar features a replaceable nose sprocket that can be changed as the tip wears, eliminating the need to replace the entire bar. Bar and nose are induction hardened for long life, and angled oil delivery holes increase flow and reduce clogging.

Solid Steel

Designed for use on high-speed professional chainsaws, the replaceable sprocket nose assembly is incorporated into the bar and riveted in place. This reduces wear on the bar nose and enables a considerably narrower bar nose. This feature helps to reduce kickback tendencies and makes the bar particularly well suited for limbing and boring work.

Solid bars are made of one piece of steel, and they generally last longer than laminated bars. They are also sturdier and offer more protection from damage than laminated bars, but they can flex undesirably in longer lengths and may need to be straightened more often.

Induction Hardened

These bars are machined from a single piece of rigid steel and feature a replaceable nose sprocket that keeps dirt and corrosive material out eliminating the need for greasing. The Nose-Replaceable Bar are induction hardened for long life, while the rails have angled oil delivery holes to increase flow and reduce clogging. These bars have a higher risk of kickback and should be used only by trained professionals.

Induction hardening is a process of quickly and selectively heating the surface of metal – in this case steel – by placing a copper coil with a significant level of alternating current close to the workpiece. Heat migrates to, and is concentrated at the surface of the workpiece through eddy current and hysteresis losses. The hot spot is then quenched – usually in a water-based polymer – transforming the martensite to a harder, stronger structure (Ref 96).

There are many variables associated with this type of heat treating including power, operating frequency, scan rate and the design of the inductor. Even a small variation in any one of these may significantly affect the final hardness of a gear tooth profile.

Sealed Nose

A favorite of professional cutters, these bars feature a solid steel body and a nose that can be replaced as it wears out without replacing the entire bar. This saves money and time by allowing you to use a fresh nose with every cutting job. The nose sprocket is sealed to keep dirt and corrosive material out, eliminating the need for greasing. Rails and nose are induction hardened for long life and the angled oil delivery holes increase flow rate and reduce clogging of lubricant. WARNING: These bars have an increased risk of kickback and should be used only by trained professionals. Includes replacement nose tip and rivet.

Oregon chain is made in several pitches - 1/4", 3/8" and 3/4". To find the right bar for your machine, match the pitch of the drive sprocket to the bar nose sprocket. If the bar has a different pitch, it may require a new nose sprocket to fit your machine.

Oil Delivery Holes

Machined from a solid piece of rigid steel, these bars are preferred by professional cutters because they allow the nose to be replaced as it wears rather than having to purchase a complete new bar. The replaceable sprocket-nose tip is sealed to keep dirt and corrosive material out, eliminating the need for greasing. The bar and nose are induction hardened for long life, and angled oil delivery holes increase flow rate and reduce clogging. These bars have a high risk of kickback and should be used by trained professionals only. Includes replacement sprocket-nose tip and rivet.
