LYHY Thin-section bearings have small cross-sections with respect to their diameter. Thin section bearings are designed to save space, lower the weight of a design and reduce friction.  Thin and extra thin-section bearings are available in inch or metric sizes and in chrome or stainless steel. These ranges are also available with cages for high-speed applications, and with extended inner rings.  Thin-section bearings are manufactured to industry standard sizes. The bearing widths and distance from bore to outside diameter remains constant regardless of the change in bore diameter. 

Due to the large diameters and thin sections of these bearings, it is necessary to address measurement and inspection. To accurately measure the bore diameter and the outside diameter of these thin section bearings special procedures must be followed. Special gages allow three to five measurements around the circumference of the diameter to be taken. These measurements are then averaged to determine the true measurement of the bearing in the unmounted free state. This procedure allows for inherent out-of-roundness.
