Skf 6203-2Z Deep Groove Ball Bearing 40mm Double Shield

Product Description

The SKF 6203-2Z is a single-row deep groove ball bearing built for high-speed rotational applications across HVAC, electric motors, pumps, and light industrial equipment. It features a double-shield design that retains grease lubrication and blocks contamination without adding significant drag. The bearing has a 17 mm bore diameter, a 40 mm outside diameter, and an overall width of 12 mm (0.4724 inches). The steel cage and grease fill make it suitable for continuous-duty operation at speeds up to 38,000 RPM. Licensed HVAC technicians, motor rewinders, and mechanical service professionals install this bearing as a direct OEM-style replacement or new installation in shaft-driven assemblies.

This bearing fits residential and light commercial applications wherever a 17 mm bore, 40 mm OD, single-row deep groove configuration is required. Common install scenarios include blower motor shafts, pump impeller shafts, small compressor assemblies, and fan drive units. The ABEC-1 tolerance rating is appropriate for general-purpose service where precision-grade bearings are not specified. The round bore accepts standard cylindrical shaft mounting without additional adapter hardware.

Key Features

• Double-shield design retains grease and blocks debris without contact-seal drag
• Steel cage construction supports high-speed operation up to 38,000 RPM
• Single-row deep groove geometry handles radial and moderate axial loads
• Grease-lubricated from the factory - no initial field lubrication required
• ABEC-1 tolerance class suitable for general-purpose mechanical and HVAC applications
• Round bore for straightforward shaft press-fit or slip-fit installation

Compatibility

Designed as an OEM-style replacement for equipment requiring a 6203-series single-row deep groove ball bearing with a 17 mm bore, 40 mm outside diameter, and 12 mm width.

Installation Notes

Bearing installation and replacement should be performed by a qualified technician. Always de-energize and lock out the motor or drive assembly before removing the old bearing. Use a bearing press or proper driver tool to seat the new bearing squarely against the shoulder - never strike the bearing directly with a hammer, as this can damage the races or cage. Follow applicable equipment manufacturer torque specifications for any housing fasteners.
