Skf 6203 2ZJEM Deep Groove Ball Bearing 40mm Od

Product Description

The SKF 6203 2ZJEM is a deep groove ball bearing designed for a wide range of rotating equipment found in HVAC, pump, motor, and general mechanical applications. It features a 40mm outside diameter, double-shield construction that contains grease and blocks contaminants without contact friction, and an ABEC-3 tolerance rating suited for moderate-precision, high-cycle service. The steel cage and single-row ball arrangement deliver reliable radial load capacity at speeds up to 19,000 RPM. Maintenance technicians and mechanical contractors install this bearing during motor rebuilds, blower shaft service, and equipment overhauls.

This bearing fits residential and light commercial rotating equipment where a 6203-series deep groove ball bearing is specified. The double-shield design makes it appropriate for grease-lubricated applications in enclosed environments, including fan motors, circulator pumps, and small power-transmission assemblies. The round bore accepts standard shaft diameters for the 6203 series. No snap ring is included.

Key Features

• 40mm outside diameter, 6203-series deep groove profile
• Double-shield construction retains grease and resists contamination ingress
• Maximum rated speed of 19,000 RPM for high-cycle motor and blower applications
• ABEC-3 tolerance rating for consistent dimensional accuracy
• Steel cage and steel housing material for durability in mechanical service
• Single-row, round-bore design for straightforward shaft installation

Compatibility

Designed as an OEM-style replacement for 6203-series deep groove ball bearings in grease-lubricated, single-row applications across HVAC motors, pump assemblies, and general rotating equipment.

Installation Notes

Installation is typically performed by licensed HVAC technicians, pump mechanics, or millwrights. De-energize and lock out all equipment before bearing removal or installation. Use a bearing press or proper driver to seat the bearing squarely against the shoulder - never strike the outer race to drive the bearing onto a shaft, as this transfers load through the ball elements and can cause premature failure. Verify shaft and housing fits are within the manufacturer tolerance range before pressing.
