Wheel bearing for 2041-68SKF OEM :SKF number:2041-68SKF SKF packing Competive price Wheel bearings function very much like typical bearings found in inline skate wheels or electric motors. The wheels spin smoothly and quietly. Without wheel bearings, the wheel of our vehicles will instantly wear out of friction, leaving us penniless because of constant replacing. As for 4-wheeled vehicles, each has a pair of front wheel bearings and a pair of rear wheel bearings. They perform two main jobs, namely: allowing the wheels with minimal friction; and supporting the vehicles' weight. The wheel bearings must be in tip-top shape to perform such tasks. The seals must be leak-free, as well. This would protect the lubricants inside from harmful contaminants outside it.
