Sealed Bearings

Sealed bearings are bearings designed with built-in seals, such as NBR rubber, HNBR rubber, FKM / Viton for higher temperatures and chemicals, or PTFE for special chemical or temperature requirements, on one or both sides. They are designed to operate in harsh, wet, dusty, or difficult-to-maintain applications to protect against dust, moisture, and other contaminants, while helping retain the lubricant inside the bearing.

BKZ Industry, as a sealed bearing manufacturing factory from China, offers sealed ball bearings such as sealed deep groove ball bearings and sealed angular contact ball bearings, as well as sealed roller bearings such as sealed spherical roller bearings, sealed tapered roller bearings, sealed cylindrical roller bearings, and sealed needle roller bearings, along with other customized bearing solutions such as customized double sealed slewing bearings.

With ISO 9001 certification and 15+ years of worldwide exporting experience, BKZ Industry can supply sealed bearings to customers worldwide based on your requirements.

Sealed Bearings Are Bearings Designed With Built In Seals

Benefits and Advantages of BKZ Industry Sealed Bearings

Sealed bearings help protect against contamination, retain lubricant, and reduce maintenance. Backed by years of bearing manufacturing experience, BKZ Industry delivers reliable sealed bearing solutions for different operating conditions.

Benefits of Sealed Bearings

Better Protection Against Contamination

Built-in seals on one or both sides help block contaminants from entering the bearing. The sealing contact or sealing gap reduces the chance of dust, dirt, moisture, or splashed water reaching the raceways and rolling elements, which helps keep the internal working surfaces cleaner.

Less Lubricant Leakage and Relubrication

Built-in seals help retain grease inside the bearing, so lubricant is less likely to leak out during operation. This supports a more stable lubrication condition, reduces grease consumption, and lowers the need for frequent relubrication, especially in applications where maintenance access is limited.

Longer Service Life

Seals help maintain proper lubrication conditions and reduce abrasive wear caused by external particles. With cleaner internal contact surfaces and more consistent grease retention, the raceways and rolling elements can operate under more stable conditions, which helps extend bearing service life.

Lower Maintenance

Because the bearing is better protected from external contamination and grease loss, it generally requires less routine lubrication, less cleaning around the bearing position, and fewer maintenance interventions. This is especially beneficial in wet, dusty, or difficult-to-service equipment.

Lower Total Operating Cost

Built-in seals help reduce lubricant consumption, maintenance frequency, unplanned downtime, and early bearing replacement. By improving lubrication retention and reducing contamination-related damage, sealed bearings can help lower the overall operating cost of the equipment.

Types of Sealed Bearings

From ball bearings to roller bearings, sealed bearings are available in different types for different working conditions. Here are some common sealed bearing types.

Sealed Deep Groove Ball Bearings

Sealed Deep Groove Ball Bearings

Built with integral seals on one or both sides, these bearings combine low friction, high running speed, and reliable grease retention in a compact design. They are widely used in electric motors, pumps, fans, conveyors, and agricultural machines, and are especially suitable for general industrial, automotive, and light-duty equipment exposed to dust or moisture.

Sealed Angular Contact Ball Bearings

Sealed Angular Contact Ball Bearings

Designed with seals and optimized raceway geometry, these bearings can support combined radial and axial loads while protecting the internal contact surfaces from contamination. They are commonly used in machine tool spindles, pumps, gearboxes, compressors, and precision drive systems, serving industries that require higher running accuracy, stiffness, and cleaner operating conditions.

FAQs About Sealed Bearings

Q1. Shielded vs Sealed Bearings: What Are Their Differences?

The main difference between shielded and sealed bearings lies in their protective structure. Shielded bearings use thin metal shields with a small clearance between the shield and the inner ring, while sealed bearings use rubber or polymer seals that create a much tighter barrier. Shielded bearings mainly protect against larger particles but cannot effectively prevent water or fine contaminants from entering. In contrast, sealed bearings provide better protection against dust, moisture, and debris. Shielded bearings generate less friction and are suitable for higher-speed applications, while sealed bearings offer better sealing performance in contaminated environments. In bearing designations, ZZ / 2Z usually indicate shielded bearings, while RS / 2RS indicate sealed bearings.

A contact bearing seal touches the inner ring, providing stronger protection against dust, moisture, and contaminants, but it also generates higher friction and slightly limits rotational speed. A non-contact bearing seal does not touch the inner ring, leaving a small clearance that reduces friction, allows higher speeds, and lowers operating temperature. Contact seals are preferred for contaminated environments, while non-contact seals are commonly used in high-speed applications.

Sealed bearings are typically pre-lubricated at the factory, so they usually do not require additional lubrication during normal operation because the seals retain grease inside the bearing and protect it from dust, moisture, and contaminants. In most standard applications, they are designed as lubricated-for-life, making them suitable for low-maintenance equipment such as motors, pumps, automotive components, and household appliances. However, under high temperatures, heavy loads, or extended operating periods, relubrication may sometimes be necessary if the bearing design allows seal removal without affecting sealing performance.

Sealed bearings are designed with seals that protect internal components from dust, moisture, and contaminants, making them suitable for harsh or dusty operating environments. Non-sealed bearings, including open bearings, do not have this protection and therefore require external lubrication and cleaner operating conditions. As a result, sealed bearings are preferred for low-maintenance applications, while non-sealed bearings are often used where regular lubrication is possible.

Sealed bearings offer excellent protection and low maintenance, but they also have some limitations. Because the seals create additional friction, they generally have lower maximum speed capability than open or shielded bearings and may generate more heat during operation. The internal grease quantity is fixed, so lubrication cannot be easily replenished in most standard designs, which may limit service life under heavy loads or high temperatures. Sealed bearings also have slightly higher running torque and may not be ideal for applications requiring ultra-high precision or minimal resistance. In harsh conditions, once the grease degrades or the seal is damaged, the bearing usually needs replacement rather than maintenance.

In most standard sealed bearings, grease is not intended to be added without removing the seals because they are designed as pre-lubricated, maintenance-free units. If relubrication is required, grease can only enter effectively when the bearing housing includes a lubrication path that allows fresh grease to pass around the seal and gradually reach the raceway during operation. In such cases, use a compatible grease, apply only a small amount to avoid excessive pressure, and lubricate slowly while the bearing rotates if possible. Over-greasing may increase temperature, damage the seals, or shorten bearing life, so sealed bearings are generally replaced rather than relubricated when grease performance declines.
