1205 K KYK JAPAN Self-Aligning Ball Bearing 25x52x15

Main Description

The 1205 K KYK JAPAN self-aligning ball bearing 25x52x15 is a double-row bearing with a tapered bore, designed to compensate for shaft misalignment and ensure stable performance in industrial applications.

Within the category of self-aligning ball bearings, the 1205 K model is engineered to automatically adjust to angular misalignment between the shaft and housing. This capability makes it highly effective in systems where shaft deflection, mounting errors, or structural deformation may occur. The tapered bore (K) allows flexible mounting on adapter sleeves or directly on tapered shafts, increasing installation versatility.

The 25x52x15 size is commonly used in medium-duty applications where both reliability and tolerance to misalignment are required.

Construction and Design

The 1205 K KYK JAPAN bearing features a specialized geometry that enables self-alignment.

Key design features:

• double-row ball bearing configuration
• spherical raceway in the outer ring
• ability to compensate for angular misalignment
• tapered bore (K) for flexible mounting
• high-quality bearing steel
• cage ensuring uniform load distribution

This design reduces stress concentrations and improves durability in systems exposed to shaft misalignment.

Industrial Applications

The 1205 K KYK bearing is widely used in applications where alignment conditions are not ideal.

Typical applications include:

• agricultural machinery
• conveyor systems
• fans and ventilation units
• light industrial gear systems
• equipment subject to shaft deflection

The self-aligning capability helps reduce wear and extends the service life of the bearing and surrounding components.
