Open Type Deep Groove Ball Bearings

1.Product Overview

Open-type bearings have low friction resistance and high rotational speed. They are shipped without pre-applied grease and have no seals, making them suitable for use inside machinery or in areas where no foreign objects can enter.

2.Key Advantages

• High Speed Capability

Without the friction drag caused by contact seals, open bearings offer higher limiting speeds compared to their sealed counterparts.

•Excellent Heat Dissipation

The open design allows lubricant to flow freely, effectively dissipating heat generated during operation.

• Lubrication Flexibility

Users can choose and replenish specific types of oil or grease at any time based on the operating conditions of the equipment.

3.Typical Applications

• Gearboxes

Utilizes gear oil within the housing for circulating lubrication.

• Electric Motors 

Suitable for high-speed motors with automatic oiling systems.

• Pump Systems

Performs excellently in oil-immersed pump units.

•Compressors

Ensures cooling and lubrication during continuous high-speed operation.

4. Why Choose GNSN Open Bearings?

Open bearings  are manufactured using high-purity bearing steel with robust cage structures, ensuring superior running accuracy at high speeds. We offer various clearance options (C2, C0, C3, C4) to match diverse thermal expansion requirements.
