With their forward-looking bearing arrangement solutions for feed spindles, main spindles, rotary tables and linear guidance units, INA and FAG have been at the forefront of the world market for decades. The bearing components alone, however, are often no longer the decisive factor for these machine subsystems.Our customers have of course benefitted directly from significant performance improvements and unique selling propositions thanks to our ready-to-fitӔ products; these compact, ready-to-fit bearings are used in accordance with the simple principle: unpack, screw mount, use. In order to...

Screw drive bearing arrangements are subjected to requirements that often cannot be optimally fulfilled by the design construction of conventional bearings. In order to design bearing arrangements for the highly dynamic operating conditions in screw drives that have high accuracy, high load carrying capacity, high rigidity, low friction, are easy to fit and maintenance-free or low-maintenance, INA/FAG has a wide range of axial angular contact ball bearings. With this well thought-out product range, ideal application-specific solutions can now be found to all the technical and economic...

Relubrication is facilitated by an axial threaded connector. The radial lubrication duct is firmly closed off. > ZKLF..-2RS-PE Figure 2 Outer ring screw mounted in bore,preloaded using locknut > 159 082 Heavy series Axial angular contact ball bearings ZKLF..-2RS and ZKLF..-2Z are also available in a heavy series. For the same shaft diameter, they have a larger cross-section and thus higher basic load ratings. Matched pairs Bearings of series ZKLF..-2RS-2AP comprise a matched pair of bearings ZKLF..-2RS, Figure 3 . The individual bearings are matched to each other.Matched bearings have an...

Axial angular contact ball bearings ZKLN are mounted in a housing bore, Figure 4 . The bearing outer ring is axially located by a cover. > ZKLN..-2RSZKLN..-2Z Figure 4 Outer ring located using cover,preloaded using locknut > 159 075 With less stringent tolerances Axial angular contact ball bearings ZKLN..-2RS-PE correspond to series ZKLN but have a runout tolerance within P5 to DIN620, less stringent diameter tolerances and the suffix PE. They are used where a lower positional accuracy is acceptable. As a result, the adjacent construction does not need to be as accurate with these bearings....

Sealing/lubricant Bearings with the suffix 2RS have lip seals and highly effective sealing.Bearings with the suffix 2Z are sealed using gap seals and are suitable for higher speeds.The bearings are greased using a lithium soap grease to GA28 and can be lubricated via a lubrication slot and lubrication holes in the outer ring (for information on GA28, see page 27). For the majority of applications, the initial greasing is sufficient for the whole bearing operating life. Schaeffler Group Industrial13 >

Bearings 7602, 7603 and BSB are designed as universal bearings, Figure 6 and Figure 7 .They can be combined in a wide range of sets for different requirements, Figure 7 . > 7602..-2RS, 7603..-2RS, BSB..-2RS Figure 6 Single row axial angularcontact ball bearings,two-bearing set in O arrangement > 159 062b 7602, 7603, BSB Figure 7 Set combinations > 159 096 Sealing/lubricant Single row axial angular contact ball bearings are not sealed and are not supplied greased. However, some sizes are fitted with seals. These bearings are greased for life using a lithium soap grease to GA28 (for...

Angular contact ball bearing units ZKLR are low-cost bearings and therefore particularly economical. They comprise a deep drawn sheet steel housing with an integral matched pair of angular contact ball bearings in an X arrangement, Figure 8 . The housing has a Corrotect > coating and is thus protected against rust. The ball bearings are sealed on both sides by lip seals or gap seals. The bearing assembly is preloaded clearance-free. > ZKLR..-2RSZKLR..-2Z Figure 8 Angular contact ball bearing unit > 159 095 Particularly easy to fit The units are particularly easy to fit. They: ΢֠ are...

Series ZKLFA has a stepped outer ring. It can therefore be screw mounted easily on the adjacent construction, Figure 9 . The flange has flattened areas on both sides, so the radial design envelope in the adjacent construction can be kept very small. > ZKLFA..-2RSZKLFA..-2Z Figure 9 Outer ring screw mountedon adjacent construction,preloaded using locknut > 159 077 Sealing/lubricant Bearings with the suffix 2RS have lip seals and highly effective sealing.
