Description

The SKF 11204 ETN9 is a specific type of spherical roller bearing from SKF, a leading manufacturer of bearings and seals. Here's a breakdown of its designation:

Decoding the Bearing Designation:

  1. 11204

    • 1: Indicates a self-aligning double-row spherical roller bearing.

    • 12: Refers to the bearing series (dimensions, load capacity).

    • 04: Indicates the bore size (04 × 5 = 20 mm bore).

  2. ETN9 (Suffixes)

    • E: Optimized internal design for higher load capacity.

    • TN9Polyamide (PA66) cage (retainer), glass fiber reinforced, suitable for high speeds and offers good wear resistance.

Key Features:

  • Self-aligning capability: Compensates for misalignment between shaft and housing.

  • High load capacity: Suitable for heavy radial and moderate axial loads.

  • Robust cage (TN9): Provides stability at high speeds and reduces friction.
