| The speed ratings given in the bearing tables may be exceeded up to 1,5 times the rating values for radial bearings and 2 times the rating values for thrust bearings provided loads are light, the friction minimised by using a minimum of lubricant and heat removal from the bearing position is good. Conversely, if loads are heavy, lubricant film formation inadequate, friction high because of excess or highly viscous lubricant, or when heat cannot be removed adequately from the bearing position, then it may not be possible to run at speeds as high as the values quoted for the speed ratings. Reference should also be made to the section "Speeds" in the SKF General Catalogue. | Unless otherwise stated, the needle roller bearings shown in this catalogue are produced to the tolerances for dimensional, form and running accuracy specified in ISO 492:1994 for radial bearings and ISO 199:1997 forthrust bearings. Tables 0 to □ on pages 17 to 19 give the tolerances for radial bearings to tolerance classes Normal, P6 and P5, and Table B on page 20 gives the tolerances for thrust bearings to tolerance class Normal. The symbols used in the tables are explained opposite. The tolerance classes in which bearings are available (either as standard, or additionally) will be found in the text preceding the product table sections. Bearings with higher accuracy than to tolerance class Normal are identified by the suffix for the tolerance class in the bearing designation (-»"Supplementary designations", page 24). The suffix is preceded by an oblique stroke. | ||||||||||||||
