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
Introduction to Self-Aligning Ball Bearings with Seals (RS or 2RS Type)
Self-aligning ball bearings with seals (RS or 2RS type) are designed to accommodate misalignment and feature seals on one or both sides. These seals provide enhanced protection against contaminants like dust, moisture, and debris while retaining lubrication, making them ideal for harsh environments and extended maintenance intervals.

Used in air handling units and fans to handle vibration and misalignment.
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.
