Self-Aligning Ball Bearings with Seals (RS or 2RS Type)

Product description:
Self-aligning ball bearings with seals (RS or 2RS type) design, the outer ring adopts a spherical raceway structure, which can automatically compensate for the installation deviation between the shaft and the bearing seat. Rubber seals (RS/2RS logo) are equipped on both sides to provide more complete dust and water protection and maintain internal lubrication.

Main applications:

Agricultural irrigation equipment

Food processing production line

Sewage treatment machinery

Mining conveying equipment

Outdoor motor

Product advantages and features:

Excellent sealing performance (IP54 protection level)

Automatic self-aligning function (compensation for angle deviation)

Maintenance-free design (lifetime lubrication)

Double-row structure enhances load-bearing capacity

Excellent corrosion resistance

Adapt to humid and dusty environments

Low friction design is energy-saving and efficient

hvac

Marine and Offshore Applications

Suitable for humid and corrosive environments where enhanced sealing is crucial.

General Industrial Machinery

Applied in applications requiring reliable performance under varying alignment conditions.

Advantages and Features

Enhanced Sealing Performance

The RS (single-side seal) and 2RS (double-side seals) provide superior protection against dust, moisture, and contaminants.

Self-Alignment Capability

Automatically adjusts to shaft misalignment, reducing stress on the bearing and surrounding components.

Low Maintenance Requirements

Sealed design ensures grease retention, reducing the need for frequent relubrication.

Durability in Harsh Environments

Ideal for applications with high exposure to contaminants, offering longer operational life.

Wide Range of Sizes and Load Capacities

Available in various sizes to meet diverse industrial requirements.

Smooth and Quiet Operation

Low vibration and noise levels ensure efficient and reliable machinery performance.

FAQ (Frequently Asked Questions)

Q: What is the difference between RS and 2RS types?
A: RS indicates a single-side seal, while 2RS indicates seals on both sides for maximum protection.

Q: Are these bearings suitable for high-speed applications?
A: They are suitable for moderate-speed applications. For very high-speed operations, unsealed or differently designed bearings might be more appropriate.

Q: Can these bearings operate in submerged conditions?
A: While the seals provide good resistance to moisture, they are not designed for continuous submerged operation. For such applications, specialized waterproof bearings are recommended.

Q: How should these bearings be maintained?
A: They are generally maintenance-free during their operational life but should be installed in a clean environment to ensure optimal performance.

Q: Can I remove the seals for relubrication?
A: The seals are not designed to be removed and replaced. Removing them may compromise the bearing's sealing integrity.

Résumé

Self-aligning ball bearings with seals (RS or 2RS type) offer a robust solution for demanding industrial applications. Combining self-alignment capability with enhanced sealing, these bearings ensure long life, low maintenance, and reliable performance in harsh environments. Their versatility and durability make them an excellent choice across various sectors, from agriculture to marine applications.

For specific models, load ratings, or technical details, consulting a bearing supplier or technical expert is recommended.
