Skf 2203 E-2RS1TN9 Self-aligning Ball Bearing 17mm Bore

Product Description

The SKF 2203 E-2RS1TN9 is a double-sealed, two-row self-aligning ball bearing designed to handle both radial and axial loads in applications where shaft misalignment is a concern. With a 17 mm bore diameter, 40 mm outside diameter, and 16 mm overall width, this bearing fits compact housings while delivering a dynamic load capacity of 2,380 pounds and a static load capacity of 573 pounds. The glass fiber reinforced polyamide cage provides lightweight durability. The double-seal configuration retains grease and excludes contaminants, reducing maintenance intervals in demanding environments. Licensed HVAC technicians, millwrights, and industrial maintenance professionals are the typical installers.

This bearing is suited for light-to-medium duty industrial and commercial applications where minor angular misalignment between shaft and housing is anticipated. Common installation scenarios include fans, blowers, conveyors, pumps, and general power transmission equipment. The Series 2203 E designation indicates a reinforced internal design optimized for higher load ratings relative to standard 2203 series bearings. Its round bore and flangeless outer ring make it a straightforward fit into standard bearing housings without the need for snap ring grooves.

Key Features

• Maximum operating speed of 12,000 RPM
• Meets ISO 15 and ISO 492 dimensional and tolerance standards
• ABEC-1 tolerance class; no snap ring or flange required

Compatibility

Designed as an OEM-style replacement or direct-fit bearing for applications requiring a 17 mm bore, 40 mm OD, 16 mm width self-aligning ball bearing in the 2203 E series.

Installation Notes

Installation should be performed by a qualified technician using a proper bearing press or mechanical fitting tool - never drive a bearing into its housing by striking the outer or inner ring directly with a hammer. Ensure the shaft and housing bore are clean, within dimensional tolerance, and free of burrs before fitting. De-energize and lock out all power to rotating equipment before bearing removal or installation. Follow the equipment manufacturer's relubrication specifications after seating the bearing.
