5203-2RS C3 Double Row Angular Contact Bearing 17mm×40mm×17.5mm AJANTA

Description

Product Overview

The 5203-2RS C3 bearing from AJANTA INDUSTRIAL is engineered as a premium double‑row angular contact ball bearing, delivering exceptional rigidity and precision for high‑speed applications. Constructed from high‑grade steel with advanced heat‑treatment processes, the bearing provides a robust load‑carrying capacity while maintaining low friction and minimal vibration. Its compact dimensions of 17 mm × 40 mm × 17.5 mm make it suitable for tight spaces, and the C3 internal clearance ensures reliable operation under thermal expansion and high rotational speeds up to 11,000 RPM. With a static load rating of 2,000 lb and a dynamic load rating of 3,100 lb, this bearing is designed to withstand demanding industrial environments, offering long‑term durability and consistent performance.

Usage

Designed for a wide range of industrial and scientific applications, the 5203-2RS bearing excels in electric motor assemblies, gearboxes, spindle drives, and robotic joints where precise axial and radial alignment is critical. Its double‑row configuration distributes loads evenly, reducing stress on shafts and extending service life. Engineers and technicians often select this bearing for high‑speed CNC machines, aerospace components, and automated manufacturing equipment that demand rapid acceleration and deceleration cycles. The bearing’s ability to handle both static and dynamic loads makes it ideal for environments with fluctuating forces, such as conveyor systems, pumps, and compressors. Its compact size also enables integration into portable devices and compact robotic platforms where space constraints are a primary concern.

FAQ

What does the C3 clearance designation mean?

C3 indicates a larger internal clearance than standard bearings, allowing for thermal expansion and high‑speed operation without excessive heat buildup.

Can this bearing be used in harsh environments?

Yes, the bearing’s steel alloy and heat‑treated surfaces provide resistance to corrosion and contamination, making it suitable for dusty or humid conditions when properly sealed.

What is the recommended lubrication method?

For optimal performance, apply a high‑temperature grease or oil compatible with steel bearings, ensuring a thin, even film that can handle the specified RPM range.

How do I determine the correct mounting orientation?

The bearing should be installed with the inner ring facing the shaft and the outer ring against the housing, aligning the angular contact faces to handle axial loads in the intended direction.

Is there a warranty or guarantee for this product?

AJANTA INDUSTRIAL offers a standard one‑year warranty covering manufacturing defects, with options for extended service contracts based on customer needs.
