INA Bearing AXS1220 it belongs to INA Bearing > Roller Bearings > Axial-angular Contact Roller Bearings , Angular contact roller bearings AXS comprise thin, formed bearing rings, between which injection-mounded plastic cages with cylindrical rollers are arranged. In contrast to comparable axial rolling bearings, series AXS has a particularly small cross-section, whilst the load carrying capacity and tilting rigidity are very high in relation to the loaded installation space. The ready-to-fit machine elements are not self-retaining and are therefore very easy to assemble as the individual parts can be installed separately.
INA Bearing AXS1220 Angular contact roller bearings SGL are preferably used if high accuracy and rigidity is required in addition to a high load carrying capacity. The particularly high precision is achieved by means of exact, machined, hardened and ground bearing rings with a triangular profile. A roller and cage assembly from wear-resistant plastic is arranged between the bearing rings. The use of quadratic rolling elements (diameter equals length) significantly improves the kinematic conditions in the bearing. The bearing runs particularly uniformly with low friction and is suitable for high speeds.
INA Bearing AXS1220, Angular contact roller bearings SGL have long proven successful in low-clearance planetary gearboxes for precision drives. Possible areas of application include handling systems, packaging machinery, food processing and robotics.
With INA Bearing AXS1220 axial angular contact roller bearings AXS, the Schaeffler Group Industrial has developed a bearing series with a high load bearing capacity and a particularly small Cross section. The design layout,cylindrical rollers (line contact at the contact surfaces) and contact angle of 450 or 600 provide for high axial load ratings and very good rigidity values. Arranged in pairs, combined loads are also possible in addition to high axial loads in both directions.
For high tilting rigidity values, the bearings can be fitted in an 0 arrangement. Where necessary, the bearings can be preload-ed to give freedom from axial clearance using an adjusting nut. Due to the specific bearing features, standard axial angular contact ball bearings can even be replaced with the more compact axial angular contact roller bearings in certain cases. The range of axial angular contact ball bearings is supplemented by radial and axial needle roller and cage assemblies produced by bending flat cages of series BF.
They are principally suitable for bearing arrangements with large shaft diameters. Due to their design, it is possible to produce cages of any diameter required.
The needle roller and cage assemblies and the associated axial bearing washers are described in TPI 203, Radial and axial needle roller and cage assemblies, axial bearing washers.
