Engineering information General bearing knowledge Bearing selection process. Pesquisa e desenvolvimento Portal do Fornecedor. Eu gostaria de saber Long service life The different sealing solutions available provide a long service life for a wide variety of applications with high contamination levels. The bearings are available open or capped with seals or shields. When designing bearing arrangements with rotating housing washer in combination with misalignment or when the shaft wobbles in relation to the housing, contact the SKF application engineering service.
Correction shown in red: In addition to the bearings presented in this section, SKF supplies insert bearings for special application requirements.
Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes. The dimension B is listed in the table, but not shown in the sketch.
Some formulas are wrong because indices are mixed up. Bearing frictional moment is not asymptotically limited to 2,0.
Cages Steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls. The requisite clearance or preload is obtained by choosing bearings from an appropriate clearance or preload class and by applying suitable fits for the bearings on the shaft and in rolwmentos housing.
Find the suitable locking method Locking with grub screws Locking with an eccentric locking collar SKF ConCentra locking Locking with an adapter sleeve Locking with an interference fit. When universally matchable bearings are mounted immediately adjacent to each other, there is no need for adjustment.

Accommodate initial misalignment The spherically shaped outside surface enables initial misalignment by tilting in the housing fig. Reduced noise and vibration levels Where high requirements on noise and vibration levels are important, SKF can provide the appropriate shaft locking method.
HME and HM lock nuts are not listed with the correct spanner. Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate.
Contact SKF prior to ordering.
Insert bearings SKF Y-bearings are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with rolamenfos specific locking device, enabling quick and easy mounting onto the shaft. They are also unable to operate at the same high speeds as bearings without filling slots.
Insert bearings (Y-bearings)
Bearing features Quick and easy to mount The different locking methods enable cataloto and easy mounting of insert bearings onto the shaft. B EG AP B EC AP Eles devem ser trocados de lugar. Bearing rings and balls SKF angular contact ball bearings undergo a special heat treatment. They are also available with or without a snap ring groove. Open bearings that are also available capped, may have recesses in More information Bearing life and load ratings.
Bearing frictional moment is not asymptotically limited to 2,0 Correction: Enviado por Arilene flag Denunciar. Replaced the graph with corrected version.
Insert bearings (Y-bearings)
The basic load ratings and the fatigue load limit for bearing NJ are too high. They can accommodate radial loads and axial loads in both directions. Under Axial clearance, bearings with designation suffix VU should be mentioned. As with all vertical shafts, be sure that the bearings rolamentps adequately lubricated. For information about these bearings, refer to the product information available online at skf.
Therefore, it should not be clamped axially, but a small gap should be maintained between the outer ring and the cover flange. Small axial clearance enables simple and cost-effective bearing arrangements e. Where to use insert bearings? Deep groove ball bearings with filling slots are available open or with shields.
