The rigid ball bearing is the most popular among all types of bearings, and is used in the majority of applications. It is a simple design and usually requires little attention in service.
It is often suitable for very high speeds and, due to the geometry of the roller track and the adaptation between the roller elements, it is suitable to support, in addition to radial loads, considerable axial loads in both directions.
Depending on the sub-type of bearing, grease, protection plates or sealant rings may be incorporated without the need for later lubrication.
The ball bearings commercialised by FERSA are subject to the following International Standards:
• The bearing steel complies with ISO 643, ISO 683 – 17, ISO 4967 and ISO 5949 standards.
• Load capabilities are in accordance with ISO 76 and ISO 281 standards
• The ball bearing tolerances are in accordance with the ISO 492 standard
• Other dimensions are subject to the ISO 15 and ISO 582 standard
• Dimensions of elastic rings and grooves are covered in the ISO 464 standard
• The internal radial set is covered in the ISO 5753 standard
• The ball dimensions are reflected in the ISO 3290 standard
Typical applications for this type of bearing include the following:
• Car wheels
• Cardan joints.
• Applications for industrial vehicle motors
