This two-piece cage is manufactured using a stamping process. It is sufficient for most applications where there are no extreme requirements. It can be used where no low starting or running friction torque are required, in applications with medium or high speeds, or if sufficient lubrication is guaranteed.<\/p>\n
This type of cage is supplied as standard with most miniature radial ball bearings when contamination, misalignment and high acceleration\/deceleration are not important. If the cage is to be used with a speed characteristic value n x Dm above 400000 (n = speed in rpm; Dm = pitch circle in mm), please consult our application engineers.<\/p>\n<\/div><\/div><\/div>
This cage is manufactured using a stamping process, is very light and prevents sticking. myonic has developed the “48” model especially for applications requiring low frictional torque or relatively low speeds.<\/p>\n
For speeds above 5,000 rpm, please contact our technical department.<\/p>\n<\/div><\/div><\/div>
For cases where conventional lubricants are not suitable, both the two-piece standard cage model “480” and model “48” can be coated with a fine layer of Teflon or other materials that have a self-lubricating effect. Teflon-coated cages are used for very long storage times, in instruments that work in a vacuum, and in optical systems.<\/p>\n
It is strongly recommended to consult our technical office before choosing coated cages and \/ or to carry out practical tests with the end application.<\/p>\n<\/div><\/div><\/div><\/div>
The cage has the task of keeping the balls in the ball bearing separated from each other around the pitch circle of the bearing.\nIn order to find the optimum solution for any ball bearing, myonic has developed many different cage designs. They differ both in their construction and in the material.\nThere is no cage that meets all conceivable requirements. The following requirements must be taken into account when selecting the most suitable cage:<\/p>\n<\/div><\/div><\/div>
Starting and running friction torque<\/p>\n<\/div><\/li>
Speeds<\/p>\n<\/div><\/li>
Acceleration and deceleration<\/p>\n<\/div><\/li>
Operating temperature<\/p>\n<\/div><\/li>
Type and quantity of lubricant<\/p>\n<\/div><\/li>
Ambient conditions during use (vacuum, chemicals, etc.)<\/p>\n<\/div><\/li>
Noise emission requirements<\/p>\n<\/div><\/li>
External vibrations<\/p>\n<\/div><\/li>
Self-lubricating<\/p>\n<\/div><\/li><\/ul><\/div><\/div><\/div>
This ball cage in the form of a crown or a comb is machined or injection-molded from various synthetic materials.\nIf the correct material is selected, this model can be supplied either oil-impregnated for a longer service life or completely dry if the ambient conditions do not permit lubrication with standard lubricants.\nThe ball cage model “23” is used in myonic ball bearings for applications with speed characteristics n x Dm of up to 1.3 million (n = speed in rpm; Dm = pitch circle in mm).\nFor even higher rated speed values, we recommend consulting our application engineers.<\/p>\n<\/div><\/div><\/div>
This is a solid one-piece cage that is machined or injection molded.\nThe myonic cage “25” is specially designed for the RA and RKA series angular contact ball bearings. This ball cage can be supplied in oil-impregnated form to increase the service life in the event of insufficient lubrication.\nThe ball pockets are designed so that the inner ring of the ball bearing can be removed without the balls falling out.\nThis means that the two rings can be installed separately if necessary. The ball cage model “25” is used in myonic ball bearings for applications with speed characteristics n x Dm of up to 1.5 million (n=speed in 1\/min; Dm = pitch circle in mm).<\/p>\n<\/div><\/div><\/div>
