3000A-2Z Double Row Angular Contact Ball Bearings

30° contact angle ZZ metal shields pre-greased

The 3000A-2Z series double row angular contact ball bearings are engineered for applications requiring high axial and radial load capacity within a compact axial envelope. The double row configuration provides bidirectional axial support while maintaining a narrow width compared to paired single-row bearings. The 30° contact angle optimizes the balance between axial stiffness and radial load capacity. Equipped with 2Z metal shields on both sides, these bearings provide effective protection against large particles while maintaining low friction torque. Pre-lubricated with high-quality lithium grease, the bearings offer maintenance-free operation for extended service intervals. Operating temperature ranges from -30°C to +110°C. Typical applications include pumps, gearboxes, electric motors, and industrial machinery where space efficiency and high load capacity are essential.

Bidirectional axial support

Double row configuration provides axial load capacity in both directions, eliminating the need for paired single-row bearings.

Optimized contact angle

30° contact angle delivers balanced performance between axial stiffness and radial load capacity for versatile applications.

2Z shielding system

Metal shields on both sides provide effective protection against large particles while maintaining low friction torque.

Compact axial width

Narrow width design fits limited axial spaces while providing the load capacity of two single-row bearings.

Conveyor rollers and drive shafts in harvesters and tractors.

Technical inquiries

What is the difference between 2Z and 2RS sealing?

2Z refers to metal shields on both sides, which protect against large particles and provide low friction torque. 2RS refers to contact rubber seals on both sides, which provide complete sealing against moisture and contaminants but with higher friction torque.

How do I set preload for 3000A-2Z bearings?

3000A-2Z bearings are supplied with internal preload settings optimized for typical applications. For specific preload requirements, consult the manufacturer. In most cases, the bearing is designed for standard preload with no additional adjustment needed.

Can 3000A-2Z bearings accommodate misalignment?

Angular contact bearings have limited misalignment capability. The maximum recommended angular misalignment is less than 0.05 degrees. For applications with misalignment, consider spherical roller bearings or self-aligning ball bearings.

Mounting

Apply force evenly to the ring being mounted. Use a press with appropriate support sleeves. Do not apply force through rolling elements.

Preload consideration

Excessive preload can cause overheating and premature fatigue. Follow manufacturer specifications for housing and shaft fits.

Storage

Store in original packaging in a dry, clean area with stable temperature. Avoid exposure to corrosive atmospheres.

Lubrication

Pre-lubricated for life. No initial lubrication required. For harsh conditions, consult manufacturer for relubrication options.
