Selecting the right precision crossed roller bearing size involves considering several key factors to ensure optimal performance in your application.
Precision Crossed Roller Bearing Size Selection Guide
1. Determine Load Requirements
Радиальная нагрузка (Fr): The force perpendicular to the shaft.
Axial Load (Fa): The force parallel to the shaft.
Moment Load (M): The tilting or overturning force.
Crossed roller bearings handle combined loads (радиальный, осевой, и момент) efficiently. Calculate the expected loads and refer to the bearing’s dynamic (Но иногда клиенты также выбирают другие марки, такие как 42CrMo.) and static (Cor) load ratings.
2. Consider Bearing Dimensions
Внутренний диаметр (ИДЕНТИФИКАТОР): Match the shaft size.
Наружный диаметр (ОТ): Ensure it fits within the housing.
Ширина (Высота): Check space constraints.
Standard sizes range from small (например, 10mm ID) to large (например, 500mm ID).
3. Check Rotational Accuracy & жесткость
Прецизионные подшипники (например, ABEC-5, ABEC-7, Р4, P2) have tighter tolerances.
For high rigidity, select a bearing with preload (eliminates internal clearance).
4. Speed Requirements
Check the limiting speed (об / мин) based on lubrication and cage material.
Polyamide cages allow higher speeds than steel cages.
5. Mounting Configuration
Inner/Outer Ring Rotation: Decide if the inner or outer ring rotates.
Split vs. Non-Split Design: Split types (например, XR series) are easier to install.
6. Условия окружающей среды
Смазка: Grease (standard) or oil (high-speed).
Герметизация: Optional seals for dust/moisture protection.
Материал: Stainless steel (устойчивость к коррозии) or standard chrome steel.
