The sleeve holds the bearing together and hence permits rapid and simple assembly. Characteristics Slim bearings type LSB consist of two inner and outer race rings with ground raceway, one plastic cage with retained balls and a surrounding metal sleeve. The sleeves and the race rings are separated; their diameter can therefore be altered elastically for mounting. Unlike standard slim bearings, Franke slim bearings type LSB can be modified in terms of clearance/preload. Mating structure The greatest levels of accuracy are achieved if the constructive design of the mating parts takes place in such a way that the handling of all diameters and surfaces relating to each other can take place within in one setting. The running accuracies indicated in the diagram are average values and may be improved by restricting the tolerances (see 'Technical information'). Technical details Material Ball race rings: 54SiCr6, rolling element: 100Cr6, cage: PA12 Temperature in use –30 °C to +80 °C, briefly up to +100 °C Circumferential speed max. 5 m/s, without seals max. 10 m/s Lubricant grease Klüber ISOFLEX TOPAS NCA52 Lubrication schedule See 'Technical information'. Tolerance details See 'Technical information'. Please find additional data on calculation, mounting and setting in 'Technical information'. Constructive example Please find construction examples, special forms, special accuracies and other options of individual tailoring to your applications and also instructions on assembly on pages 11 – 19. Rotational resistance The rotational resistance indicates the preload on the bearing assembly. It is dependent on the respective type and the race ring diameter. The values indicated in the diagram are standard values and can be aligned individually.
