22234CDE4C3S11 NSK Spherical Roller Bearing 170x310x86

Heavy-Duty Spherical Roller Bearing for High Loads

C3 Clearance and S11 Vibration Specification

Technical Data and Industrial Applications

Main Description:
The 22234CDE4C3S11 NSK 170x310x86 is a double-row spherical roller bearing engineered for extreme radial and axial loads in demanding industrial environments. With dimensions 170x310x86 mm (inner diameter x outer diameter x width), this bearing is designed for heavy machinery, mining equipment, vibrating screens and large transmission systems.

Unlike a standard deep groove ball bearing (łożysko kulkowe), a spherical roller bearing accommodates shaft misalignment and housing deflection without compromising performance. Its self-aligning design ensures stable operation even under dynamic loads and structural deformation.

The C3 internal clearance provides increased radial clearance, allowing reliable operation at elevated temperatures and under heavy load conditions. The S11 specification indicates a vibration-resistant design, commonly used in vibrating machinery and high-impact industrial applications. This makes the bearing suitable for crushers, screens, mills and other equipment exposed to continuous vibration.

Precision raceway geometry and optimized roller profiles ensure even load distribution and reduced stress concentration. The bearing can operate within a robust bearing housing (obudowa łożyskowa) or as part of a complete bearing unit (jednostka łożyskowa) in large industrial assemblies.

The 22234CDE4C3S11 NSK delivers high durability, long service life and consistent operational stability in heavy-duty industrial applications where reliability is critical.
