Precision, which is one of the most important indicator of wheel spacers quality, has become the core part of verifying the production level of a manufacturing enterprise. At BONOSS, we have achieved precision control at 0.02mm. Producing wheel spacers with such precision can not only ensure high quality and safety but also reduce waste, improve economic efficiency, meanwhile, more environmentally-friendly. In addition, they offer a smooth installation experience.
Parallelism is a measurement of whether two planes of an item are parallel to each other, or whether two lines are parallel. In wheel spacers, parallelism means the parallelism degree of the upper and lower planes. Parallelism affects the degree of force transfer between wheel parts. The smaller the tolerance value, the higher the accuracy, the better the surface quality, the higher the reliability. It is very important for whether the spacers function properly.
Perpendicularity is a measurement of whether two surfaces of an object are perpendicular to each other, or whether two lines intersect at a right angle. In wheel spacers, perpendicularity means the perpendicular degree of the upper/lower planes and side planes. Perpendicularity affects the performance of force transmission between wheel parts. The higher the precision, the better the perpendicular degree, the better performance of bearing stress.
Coaxiality is the tolerance for how exactly the central axis of one cylinder is to another. In wheel spacers, coaxiality means the coaxially degree of the centric rings and the PCD circle. Coaxiality conditions can be vital for shafts supporting heavy and varying loads, such as car and truck axles. High coaxiality ensures that the axle and the wheel are kept on the same centerline, meaning no additional force, no vibration, no annoying noise, less energy loss, less fatigue damage, longer service life.
