FAG RS – Robust and Fast High performance series for main spindles

High performance series for main spindles FAG RS – Robust and Fast Ordering example: HCRS71914-DDLR-T-P4S-UL Bearing designs Direct Lube bearings with lubrication RS spindle bearings are fitted with large holes and seals on the outer ring. ball sizes, have a uniform nominal The possible bore diameters range in contact angle of 20° and are produced, dimension series 719 from 10 mm like all FAG spindle bearings, an accuracy to the FAG standard P4S with running tolerances to the standard P2. The bearings are fitted as standard with a phenolic resin cage guided on 0001A220 the outer ring. The universal...

In those applications where the high load Less sensitive to tilting carrying capacity of X-life ultra bearings Comparison of B, High Speed and the advance and retardation increases with Cronidur rings is not required, on an almost linear basis with the radial the RS series offers an economical load. In the case of the HC bearing, alternative for achieving high speed radial load on an example spindle Extraordinarily robust design the bearing that is closest to the load, A comparison of the increase in preload there is an significantly flatter increase initially due to the higher rigidity but a...

The HCRS bearing also shows an Under radial load and combined loading, Under combined axial and radial load, almost linear progression, but with a significantly smaller increase than principally the determining factor. in the case of the B spindle bearing Under pure radial load, the permissible with ceramic rolling elements. radial load of the HCRS bearing in sensitive to tilting due to load or defects in the adjacent components than HC or HCB bearings. The risk of cage failures 70% higher than that of the HCB bearing, the fatigue limit of 2 000 MPa compared to HC bearings based on small sizes,...

High rigidity Studies of the load carrying capacity of The new FAG high performance series bearing arrangements in a hypothetical performance series, Figure 8. for spindle bearings RS is characterised milling spindle with four HCB71914 and HC71914 bearings rigidly adjusted in a tandem-O-tandem arrangement (thermally optimum bearing spacing 210 mm) under axial, radial and The RS variant of the HC bearing has only slightly lower axial rigidity due to the smaller contact angle of 20° than the HCB bearing with a contact angle of 25°. It achieves almost the same radial combined loading demonstrate...
