RKS.160.14.0414 Slewing Bearings

RKS.160.14.0414 Crossed Roller Slewing Bearing Without Gear – High-Rigidity Precision Turntable Solution

Luoyang Heng Guan Bearing Technology offers the RKS.160.14.0414 Slewing Bearings, a single row crossed cylindrical roller slewing ring without gear, engineered for high-precision rotary applications. With a 414 mm mean raceway diameter, 486 mm outside diameter, 344 mm bore, and 56 mm height, this compact bearing weighs just 28 kg yet delivers an impressive static axial load rating (C0) of 595 kN and dynamic rating (C) of 167 kN. Manufactured to ISO9001 standards using induction-hardened C45E/42CrMo4 rings (HRC 55-62) and 14 mm 100Cr6 through-hardened rollers, the products achieve running accuracy of ≤0.2 mm radially and ≤0.3 mm axially. This drop-in replacement for SKF RKS.160.14.0414 and INA XSU14 0414 serves robotic arms, CNC rotary tables, medical CT scanners, radar systems, and solar trackers worldwide.

Technical Specifications of 160.14.0414

Brand Interchange Reference

You can upgrade to the four-point contact ball bearing RKS.060.20.0414 while maintaining the same mounting dimensions. Geared versions include RKS.161.14.0414 (external gear) and RKS.162.14.0414 (internal gear).

Why Choose RKS 160 14 0414 Crossed Roller Design?

The crossed cylindrical roller arrangement in the RKS.160 14mm crossed cylindrical roller slewing bearing provides exceptional rigidity compared to traditional ball bearings. Each roller alternates 90 degrees in orientation, enabling the bearing to handle combined axial, radial, and moment loads simultaneously within a compact 56 mm height.

Zero clearance or preload configuration eliminates play, ensuring precision positioning critical for robotic waist joints and CNC indexing tables. This medium size crossed roller slewing bearing 0414 delivers lower frictional torque than multi-row roller designs, reducing motor power requirements in battery-operated equipment.

The RKS.160.14.0414 Slewing Bearings feature an induction-hardened raceway (HRC 55-62) that extends service life even under continuous oscillation. Integral NBR seals retain NLGI 2 lithium EP grease while excluding contaminants, meeting IP65 equivalent protection standards. Four M10×1 grease fittings enable purge lubrication, critical for maintaining performance in dusty industrial environments.

Q: Is RKS.160.14.0414 equivalent to INA XSU14 0414?

A: Yes, the XSU14 0414 equivalent SKF RKS.160 offers dimensional interchangeability. The INA version has a 484 mm outside diameter (2 mm smaller) but shares identical bore, height, and bolt patterns. Both bearings mount without modification in most applications.

Q: What is the load capacity of 160.14.0414?

A: Dynamic axial load rating (C): 167 kN. Static axial load rating (C0): 595 kN. These values apply to pure axial loading per ISO 281 standards. For combined loads, consult our engineering team for equivalent load calculations.

Q: Can RKS.160.14.0414 be supplied with gears?

A: Yes. The external gear version is designated RKS.161.14.0414, and the internal gear version is RKS.162.14.0414. Both maintain the same mounting dimensions as the no-gear model. Gear modules and tooth counts vary based on application requirements. We also offer the four-point contact ball bearing RKS.060.20.0414 with identical bolt holes for applications prioritizing cost over rigidity.

Q: What is the recommended re-lubrication interval?

A: For continuous rotation applications, relubricate every 100 operating hours using NLGI 2 lithium EP grease through the four M10×1 fittings. In oscillating service (robotic arms), extend intervals to 200 hours. Automatic lubrication systems help purge contaminants in dusty environments. Always follow your equipment manufacturer's specifications.
