2204 2RS TV NKE Self-Aligning Ball Bearing 20x47x18

Product Overview

The 2204 2RS TV NKE 20x47x18 is a self-aligning ball bearing designed for applications where shaft misalignment, mounting tolerances or slight shaft deflections may occur during operation. Its double-row ball configuration and spherical raceway allow the bearing to compensate for angular misalignment while maintaining smooth, stable rotation. The 2RS sealing ensures reliable protection against dust, moisture, and contamination, improving service life even in demanding industrial conditions.

Key Features and Benefits

This bearing features a TV polymer cage, engineered to provide excellent wear resistance, reduced friction, and silent operation. The seals on both sides retain lubrication inside the bearing, minimizing maintenance frequency and improving operational reliability. The optimized internal geometry delivers consistent performance under varying loads and speeds, making it well-suited for continuous industrial use.

Industrial Applications

The 2204 2RS TV NKE bearing is commonly used in:

• Bearing units and housed bearing assemblies

• Electric motors and drive systems

• Industrial conveyors and processing machinery

• Automation and mechatronic mechanisms

Its ability to correct misalignment makes it a preferred solution for maintenance teams seeking durability and stable performance in dynamic environments.

Main Product Description

The 2204 2RS TV NKE 20x47x18 self-aligning ball bearing is engineered for reliable performance in industrial applications where operational alignment cannot be perfectly guaranteed. Its double-row construction and spherical outer raceway allow the bearing to accommodate angular misalignment between the shaft and housing without introducing additional stress or friction. This makes it highly effective in systems where shaft bending, installation inaccuracies or structural deformation must be absorbed during operation.

The 2RS rubber seals on both sides help retain lubricant and prevent ingress of contaminants such as dust, process particles, or moisture. This is particularly important in industrial machinery operating in environments with elevated particulate exposure or frequent temperature variation. The TV type polymer cage reduces mass and enables quieter, smoother running, making the bearing suitable for high-speed and continuous-duty applications.

The bearing’s compact dimensions — 20 mm bore, 47 mm outside diameter, 18 mm width — make it compatible with a wide range of standard bearing housings and unit assemblies. Its versatility and proven durability make it a popular choice across manufacturing, equipment servicing, power transmission, packaging machinery and automated systems. When stability, longevity and tolerance to misalignment are priorities, this NKE bearing provides a dependable solution with low maintenance requirements.
