Lubri Jet® is an angled oil hole
that virtually eliminates bar oil-hole plugging. The standard perpendicular
oil hole position is changed to an angular position. The Lubri Jet® oil
hole slopes up (towards the top of the bar) and forward (towards the nose).
A Lubri Jet® oil hole is also approximately 40 per cent smaller in diameter
than a standard hole. The smaller hole increases the velocity of the oil
as it enters the bar, which helps clear sawdust and debris away from the
hole during operation.
BENEFITS
The surface area on the chain's drive links exposed to incoming
oil at the point where oil enters the bar groove is increased by 500
per cent.
Improved chain and bar lubrication results in a longer service life.
Drive links will pull sawdust and chips away from the oil-hole during
operation.
The smaller size of the Lubri Jet® oil hole increases the velocity
of incoming oil with no decrease in the volume of oil entering the
bar groove.
Oil velocity at the point where oil enters the bar groove is increased
by as much as 480 per cent.
Bar oil hole plugging during felling and bucking operations is reduced
by 80 per cent. Sawdust and chips are blasted out.
Less down time on the job.
Lubri-Dam™ is exactly what its
name implies, a dam that helps keep lubricant where it's needed. The Lubri-Dam™
feature resembles a small barrier located in the bottom of the guide bar’s
groove, just behind the oil-hole.
BENEFITS
Oil in the bar groove is prevented from running out of the bar's
tail, keeping more lubricant available to the bar and chain.
In tests, the thickness of oil film on the rails of bars with Lubri-Dam™
increased 135 per cent over the oil film thickness found on bars without
Lubri-Dam™.
Bar oil hole plugging is reduced because the Lubri-Dam™ helps deflect
sawdust and wood chips away from the oil hole.
An increase of available oil and a reduction of oil hole plugging
combine to improve overall lubrication.
Cutting performance is enhanced and service life of the bar and
chain is maximised.
