It is built for environments where a reliable, low-maintenance wheel is needed on a regular basis, such as warehouses, builders' yards, and agricultural settings. Roller Bearing Included: The wheel comes with a roller bearing pre-fitted, so it is ready to mount directly onto a compatible sack truck axle without sourcing a separate bearing. This makes it a straightforward like-for-like replacement for worn or damaged wheels on standard sack trucks using the 3.50-4 tyre size.
