Heavy duty applications Crabbing has traditionally been an issue in heavy duty applications across a range of industries, and engineers have struggled with means to combat the problem. For example, fork truck manufacturers have been aware for many years that there was a tendency within the mast for the bearings they were using to crab. This meant that the mast bearing would actually skid or crab or even, in the worst cases, lock in the mast channel. To get around this, many fork truck manufacturers used a second 'side load roller' bearing to prevent that from happening. The combined roller bearing simply brings this solution into one unit by combining the main load carrier (radial bearing) with the anti-twist bearing (axial bearing).
