MBW static wheels are built to standards suitable for vibratory compactors. That means heavier bearings (to 1,100,000 lbs. static load), heavier shafts (to 710,000 lbs. shear strength) with a correspondingly heavy frame that supports the wheel at both ends to minimize frame and shaft deformation. Our static wheels are heavily built because they can be converted to vibratory wheels when need arises.
