Ball bearing 6208 ZZ — No name — single-row deep groove shielded bearing

6208 ZZ is a single-row deep groove ball bearing with metal shields on both sides, designed to provide reliable radial support in rotating assemblies. The bearing features a hardened inner and outer ring with a cage-guided ball set, offering smooth rotation, low friction and extended operating life under typical radial load conditions. The ZZ metal shields help reduce contamination ingress and retain lubricant inside the bearing while allowing higher speeds compared with contact seals.

Advantages

The shielded design reduces exposure to dust and splashing while requiring minimal maintenance, and the deep groove geometry accommodates radial loads with simple mounting and reversal capability. Its metal shields permit good heat dissipation and allow the bearing to operate at moderate to high speeds, and the single-row configuration keeps the unit compact and suitable for confined housings. The construction materials provide dimensional stability and consistent rotational accuracy.

Suitable for

• Electric motors and generators
• Gearboxes and reduction drives
• Pumps and fans
• Conveyor rollers and material handling equipment
• General industrial machinery requiring radial support

Key specifications

• Bearing type: single-row deep groove ball bearing
• Shielding: metal shields on both sides (ZZ)
• Load direction: primarily radial loads
• Speed capability: moderate to high operating speeds (shielded design)
• Sealing characteristic: non-contact metal shields for reduced contamination ingress and retained lubricant
• Construction: hardened inner and outer rings with cage-guided balls
• Application environment: indoor industrial, machinery housings with limited contamination

How to use

Select the 6208 ZZ bearing to match the shaft diameter and housing bore of your equipment. Install the bearing using appropriate press or shrink-fit methods to avoid applying force through the rolling elements; support the inner ring when mounting on the shaft and the outer ring when pressing into a housing. Ensure correct axial positioning and use proper lubricant compatible with the application if relubrication is required. Check alignment and preload where applicable and verify free rotation before full system operation.

Usage recommendations

Operate the bearing within manufacturer-recommended speed and temperature ranges, avoid direct exposure to heavy contamination or water ingress, and perform periodic inspections for noise, vibration or increased running temperature. For environments with heavy dust or moisture, consider bearings with contact seals or additional protective measures. Maintain compatible lubrication practices to extend service life.
