3806 ZZ INA - Double Row Angular Contact Ball Bearing 30x62x30.2

Bearing type and function

Double row angular contact ball bearing for combined loads

The 3806 ZZ INA is a double row angular contact ball bearing designed to carry radial loads and axial loads in both directions. Its internal geometry corresponds to a matched pair of single-row angular contact bearings, combined into one compact and rigid bearing unit.

Design and sealing

ZZ metal shields and maintenance-free operation

This bearing version is equipped with ZZ metal shields on both sides, providing effective protection against solid contaminants while retaining the factory-filled lubricant. The sealed design supports stable, low-maintenance operation in industrial environments where reliability and long service life are required.

Industrial applications

Drives, gearboxes, machinery and compact bearing units

The 3806 ZZ INA angular contact ball bearing is commonly used in:

• industrial machinery and automation systems

• mechanical and electric drive units

• gearboxes and transmission assemblies

• compact bearing housings and integrated bearing units

Its high rigidity, precise shaft guidance and high durability make it suitable for continuous industrial operation.

Main description

The 3806 ZZ INA is a high-quality double row angular contact ball bearing engineered for applications where combined radial and axial loads must be transmitted reliably. Thanks to its angular contact raceway design, the bearing supports axial forces in both directions while maintaining excellent radial load capacity.

The double row configuration provides increased stiffness and load distribution compared to single-row solutions, making this bearing ideal for compact machine designs. ZZ metal shields protect the rolling elements from contamination and ensure long-term lubricant retention, reducing maintenance requirements and downtime.

This angular contact ball bearing is widely used in industrial machinery, drive systems and bearing housings where high durability, operational stability and precise rotation are critical. Its proven design makes it a dependable choice for B2B customers in manufacturing, maintenance and mechanical engineering sectors.
