6203 2RS/15 TYB 15x40x12 Deep Groove Ball Bearing

Main description

The 6203 2RS/15 TYB deep groove ball bearing is a specialized variant of the widely used 62 series, designed for applications requiring a reduced inner diameter of 15 mm while maintaining standard outer dimensions.

Unlike standard 6203 bearings, this version provides a unique configuration that allows installation on smaller shafts without modifying the housing. Within the best ball bearings category, it serves as a practical adaptation solution for maintenance, repair, and custom mechanical systems.

The 6203 2RS/15 TYB bearing is a precision rolling element engineered to support radial loads and light axial loads in compact mechanical assemblies.

With dimensions 15x40x12 mm, it is commonly used where space and compatibility constraints require a non-standard bore size while keeping standard external dimensions.

Design and construction

The 6203 2RS/15 TYB bearing is built for reliability and easy integration:

• double-sided 2RS rubber seals for protection against dust and moisture
• standard 62 series geometry ensuring compatibility with common housings
• reduced inner diameter for 15 mm shafts
• factory lubrication for immediate installation

This construction enables quick replacement and reliable operation in various technical applications.

Industrial applications

The 6203 2RS/15 TYB deep groove ball bearing is used in:

• electric motors with non-standard shafts
• household and light industrial equipment
• compact pumps and ventilation systems
• workshop machinery and repair applications
• retrofit and adaptation projects

It is especially useful in servicing situations where maintaining the original housing is required.
