Why Choose the RKS 161 14 1094 Crossed Roller Slewing Bearing?
Zero-Clearance Design for Maximum Stiffness
The crossed cylindrical roller arrangement eliminates internal play, delivering significantly higher rigidity than four-point contact ball bearings in the same envelope. This makes the 161 series crossed roller slewing bearing external gear ideal for applications where deflection under load directly affects positioning accuracy or operational safety.
Drop-In Replacement Capability
Your RKS.161.14.1094 replacement or substitute needs are fully addressed: our bearing shares exact mounting dimensions with SKF RKS.161.14.1094, Rothe Erde 161, and INA XSA14 1094N equivalents. It's also mounting-compatible with RKS.061.20.1094 four-point contact ball bearings, allowing you to upgrade to crossed roller technology without modifying your equipment structure.
Proven Load Capacity for Heavy-Duty Service
With a static axial load rating of 1,450 kN and dynamic rating of 279 kN, this 1024x1198.4x56 slewing bearing handles the combined axial, radial, and tilting moment loads typical in tower crane slewing mechanisms and excavator swing platforms. The normalized external gear withstands 21 kN continuous and 72 kN peak tooth forces over 3,000,000 cycles.
High-Quality Material and Heat Treatment
Manufactured from structural steels (C45E, 42CrMo4, or 50Mn) with induction-hardened raceways (HRC 55–62, 3–6 mm depth), the bearing balances core toughness with surface wear resistance. Through-hardened 100Cr6 rollers and NLGI 2 lithium EP grease via four M10×1 fittings ensure long service life even under shock loads.
Complete Series and Customization Support
Beyond the 161.14.1094 external gear model, we offer the RKS.160.14.1094 (no-gear) and RKS.162.14.1094 internal gear versions. Our team handles personalized non-standard customization, old product mapping, and technical consultation—all backed by CNC vertical lathes, gear shapers, and machining centers for diameters up to 10,000 mm.
Primary Application Areas
Tower Crane and Mobile Crane Slewing Mechanisms
The crossed cylindrical roller slewing ring m8 z148 is a standard selection for medium-capacity tower cranes. The external gear meshes directly with the slewing drive pinion, while the crossed roller raceway absorbs lifted-load axial forces and boom tilting moments with minimal angular deflection. This ensures operator safety and precise load placement.
Large Rotary Tables and Welding Positioners
Zero-clearance execution makes the 161 14 1094 series ideal for welding positioners, test turntables, and indexing stations where angular repeatability under load defines output quality. The high stiffness prevents workpiece drift during multi-pass welding or precision machining operations.
Material Handling and Excavator Swing Platforms
Where swing platforms face alternating shock loads—such as bucket digging cycles—the crossed roller raceway absorbs impacts without permanent deformation. This reliability advantage over ball designs in the same 1198.4 mm OD envelope reduces downtime and maintenance costs in demanding excavator and material handler applications.
