Advantage of excavator boom bushings

Forged Chromoly Steel Core

Assembled from 4140 chromoly steel and individual vacuum heat-treated to provide maximum tensile strength - it can withstand over 200,000 PSI before deformation

Laser Measured Precision Bores

Computer-calibrated with a .01mm concentricity tolerance to align with boom pins and eliminate uneven wear patterns

Spiral Oil Channels & Micro-Reservoirs

Patented grease lubrication system can keep grease over five times longer than standard bushings while preventing dirt from intrusion

Dual-Layer Surface Engineering

combining carburizing (HRC 58-62 surface) in conjunction with a tough core (HRC 32-35) provides wear resistance that lasts 40% longer than OEM bushings.

excavator boom bushings

1.Daily digging workMinimize wear between boom joints, Assist arm movement smoothly while digging

2. Heavy lifting jobs Supporting load when moving heavy loads. Preventing wobble during lifting operations.

3.To effectively handle shocks from uneven ground conditions, prolong industry working life.

FAQ

So what about the boom bushings?

Boom bushings are hard bearings made to fit between the pivot points of the boom in order to soften the pulsation and wear of metal-on-metal, and ultimately providing you with a smoother operating experience.
When the boom appears to have excessive play, if there is a squeaking noise or visual signs of wear on the bushing surface, these signs indicate that replacing them may be necessary.
Definitely, that is a very bad idea. You should always use OEM specifications bushings to assure proper fitment, and proper functioning, which will diminish the chances of a boom component failing prematurely.
The bushings must be pressed in evenly using adequate tools. Hammering bushings in can distort the bushing or damage the boom housing.

What Our Clients Are Saying

Tom
Tom

"Cheap bushings that I needed to replace every four months for a Cat 336, just lasted 14 months (and counting). Saved $2,800 in downtime alone this year."

Lisa

"Our Deere 210's bucket had play in it after only 300 hours. We've had these bushings for almost 800 hours, and, same as day one for fitment & precision demise. A game changer."

David
David

"I bought these for my Kubota KX-057 after throwing away money on cheap bushings and the wear never showed and there was no play after a year. Should have switched sooner."

James
James

"All we do is smash bushings in our rock quarry, and bash them hard... normally would have killed bushings in a month or so for hard granite moves. These lasted 5 months moving granite. Unmatched amount of wear resistance - still serviceable."
