This description naturally incorporates key phrases like “6836 2RS,” “sealed deep groove bearing,” “180x225x22 bearing,” and “double sealed bearing.”

The 2RS sealing prevents ingress of dust, moisture, and debris, thus extending service life and reducing maintenance. The robust design ensures the bearing can handle radial loads typical of rotating machinery, transmissions, heavy equipment, and industrial drives.

Applications & Benefits

• Ideal for heavy rotating machinery, gearboxes, shafts, and industrial drives

• Effective in environments with dust, dirt, or moisture (e.g. mining, material handling, outdoor equipment)

• Maintenance-friendly due to sealed construction (2RS)

• Pre-lubricated for immediate installation and operation

• Balanced for radial loads; moderate axial capacity

• Suitable for continuous duty and heavy stress conditions

Technical Data & Specifications

While specific dynamic and static load ratings depend on manufacturer specification, the model 6836 is considered “thin section” in many catalogs — i.e., a bearing with a relatively slender cross-section but retaining robustness for large diameters.

Installation & Maintenance

1. Use clean tools and wear gloves to avoid contaminating the bearing or seals.

2. Align shaft and housing tolerances correctly to avoid stress or misalignment.

3. Press or heat-fit gently; avoid shock or hammering on the seals.

4. As the bearing is sealed (2RS), external lubrication is not required under normal conditions.

5. Monitor temperature, vibration, or noise—excessive deviations may indicate problems.

6. In harsh environments, consider periodic checks despite the sealed design.

FAQ (Frequently Asked Questions)

Q: What does “2RS” mean in 6836 2RS?
A: It denotes double rubber seals on both sides of the bearing, providing protection against dust, moisture, and contaminants.

Q: What are the dimensions of this bearing?
A: 180 mm (inner diameter) x 225 mm (outer diameter) x 22 mm (width).

Q: Is the bearing pre-lubricated?
A: Yes, the bearing is factory-lubricated and sealed (sealed for life), so no extra lubrication is necessary under standard operating conditions.

Q: What kinds of applications suit this bearing?
A: It suits heavy-duty rotating machinery, industrial drives, gearboxes, shafts in harsh or dusty environments where protection and durability are key.

Q: Can I open the seals or relubricate?
A: The 2RS seals are not generally meant to be removed. Opening may impair sealing integrity. If relubrication is needed, it must be done carefully or by replacement of the bearing.
