Ball bearing 6202 ZZ, shielded double metal shields, single-row radial bearing

Single-row radial ball bearing 6202 ZZ with double metal shields (ZZ) is designed to support radial loads and enable smooth rotation of shafts in a variety of compact mechanical assemblies. The shielded construction reduces ingress of dust and light contamination while helping retain lubricant inside the bearing, making it suitable for general-purpose applications where some protection and long service life are required. Typical installations include small electric motors, gearboxes, pumps and other rotating equipment where a single-row radial bearing is appropriate.

Advantages

The double metal shields provide a balance between protection and low friction: shields help prevent direct entry of particles while maintaining relatively low running resistance compared with sealed variants. The single-row design offers a compact radial load-carrying solution with straightforward mounting in standard housings and on shafts. Metal shields also tolerate moderate operating temperatures and do not require removal for routine lubrication during assembly.

Suitable for

• Small electric motors and fans
• Gearboxes and transmissions with radial load requirements
• Pumps and compressors with limited contamination
• General-purpose rotating shafts in light machinery

Key specifications

• Bearing type: single-row deep groove ball bearing
• Shielding: double metal shields on both sides (ZZ) for dust protection
• Load direction: primarily radial loads
• Contact arrangement: non-contact metal shields allowing retained lubrication
• Construction: hardened inner and outer rings with precision balls and cage
• Typical applications: electric motors, gearboxes, pumps, small machinery

How to use

Install the bearing on a clean, appropriately sized shaft and ensure housing bores are free of burrs and contamination. Use correct interference or clearance fits as specified by the machinery designer to avoid misalignment or preloading that could shorten service life. During assembly, avoid hammering directly on the bearing rings; apply force only to the ring being fitted. If additional lubrication is required, use a grease compatible with the equipment and the bearing's operating temperature range; metal-shielded bearings typically retain factory lubrication but can accept replenishment when necessary.

Usage recommendations

Operate the bearing within recommended radial load and speed limits for its size, monitor for unusual noise or vibration, and maintain a routine inspection schedule. Avoid exposing the bearing to heavy contamination, water ingress, or misalignment. When replacing bearings, inspect mating components for wear and ensure proper cleanliness and lubrication to maximize service life.
