INA 3806-2Z 2 Row Angular Contact Ball Bearing - 30 mm ID, 42 mm OD 10 mm Race Width

This angular contact ball bearing provides reliable support for assemblies requiring angular load accommodation in rotating equipment. It is configured with two rows of balls to manage combined forces and is intended for use where continuous rotation at elevated speeds is needed. The bearing is supplied unsealed and is designed for industrial settings in automation, electronics and mechanical systems.

• 25° contact angle improves axial load handling in both directions
• Fibreglass reinforced polyamide cage reduces friction and noise
• 6100N dynamic load rating extends service life under variable loads
• 6000N static load capacity resists deformation during overloads
• 13300r/min limiting speed enables high-speed operation when lubricated
•N internal clearance permits precise axial positioning in assemblies

• Suitable for spindle supports in Compact motors
• Ideal for high-speed rotary encoders in automation
• Used with precision gearboxes in robotics joints
• Can be used for shaft supports in electronic cooling fans

Use a machined shaft with a 30mm bore tolerance matching the bearing’s internal diameter and establish a firm yet non-interfering press fit to maintain alignment.

Select a lubricant with low viscosity suitable for 13300 r/min operation, and apply appropriate re-lubrication intervals based on duty cycle and operating temperature.

The fibreglass reinforced polyamide cage offers good dimensional stability and wear resistance, which can extend re-lubrication intervals compared with plain polymer cages under similar conditions.
