Допуски подшипников
Допуски подшипников
Допуски подшипников стандартизированы на отечественном и международном уровне в соответствии с системой стандартизации ISO. Подшипники изготавливаются с определенной точностью и, в общем, характеризуются классом точности P0. На заказ, могут изготавливаться подшипники, имеющие класс точности P6, P5, P4 и P2. Последние типы подшипников производятся для специальных назначений таких, как высокоточная направляющая оси или сверхвысокие скорости качения. Предоставляются таблицы допусков, касающиеся:
- размеров подшипников;
- размеров закругления кромок подшипниковых колец, монтажных фасок.
Условное обозначение допусков
Допуски радиальных подшипников нормального класса точности (за исключением конических роликоподшипников)
