FAG 23038-E1A-XL-K-M-C3 SPHERICAL ROLLER BEARING 190260720030

Spherical roller bearings are a mechanically optimized solution for applications subject to multiaxial loads and dynamic misalignments. Their dual-row spherical roller design gives them an inherent ability to compensate for shaft deflection while simultaneously supporting high radial loads and bilateral axial loads.

Features:
This FAG model features a solid, one-piece brass cage, ensuring structural rigidity and thermal resistance suitable for heavy-duty applications. Its 1:12 tapered bore, combined with an increased C3 radial clearance, allows for adjustable mounting via a sleeve or on a tapered shaft, providing fine adjustment of radial clearance and a secure fit of the inner ring. The E1A design, which lacks a central shoulder and features two lateral retaining shoulders on the inner ring, promotes uniform force distribution and reliable axial guidance. Schaeffler’s X-life label guarantees enhanced surface quality on the raceways, optimizing fatigue life and performance under cyclic loading. The assembly is designed to operate at high speeds while minimizing internal heating and energy losses.

Maintenance:
The bearing’s open design allows for direct inspection of the raceways and internal components. Three lubrication ports, combined with an annular groove on the outer ring, enable relubrication during operation, provided the mounting interface is suitable. The choice of lubricant (grease or oil) depends on thermal, dynamic, and environmental loads. Special attention must be paid to the cleanliness of the housing and mounting interfaces during maintenance to prevent particulate contamination. The brass cage retains its mechanical properties up to 200°C in continuous service, provided the lubricant used is compatible.

Sealing:
With no seals, this bearing is characterized by low rolling resistance, superior high-speed performance, and better heat dissipation. However, this configuration requires strict control of the operating environment. The absence of internal seals results in increased vulnerability to contaminants (abrasive dust, liquid splashes, moisture). It is therefore recommended to supplement the assembly with suitable external protective devices (covers, radial seals, or labyrinth seals).
