2136678 W50 Milling Solid Tire Wheel Puncture Free Rear Wheel Road Milling Machine Spare Parts

2136678 is the solid rubber rear wheel specified for the W50 cold milling machine. Unlike a pneumatic tyre, the load is carried by the rubber section itself, so a cut from milled aggregate or a steel offcut cannot deflate the wheel and stop the machine mid-pass.

The rubber is moulded onto a steel rim with a flat back plate and a drilled bolt circle matching the W50 rear hub. The complete wheel is supplied assembled and balanced, so it is bolted straight onto the axle without a tyre press, tube or balancing step.

Because there is no air pressure to check, the wheel holds a constant rolling height across the whole service interval. That keeps the rear axle level and the milling depth consistent, which matters when a contractor runs several W50 units on the same job and wants the same result from each machine.
