Product Application
Spherical bearings are used in countless applications, wherever rotational motion must be allowed to change the alignment of its rotation axis. A prime example is a tie rod on a vehicle suspension. The mechanics of the suspension allow the axle to moveup and down, but the linkages are designed to control that motion in 1 direction only and they must allow motion in the other directions. Spherical bearings have been used in car suspensions, driveshafts, heavy machinery, sewing machines, and many other applications.

What are the Signs of a Damaged or Worn-out Slewing Bearing that Requires Replacement?
Identifying the signs of a damaged or worn-out slewing bearing is essential for preventing potential failures and ensuring equipment reliability. Here are common indicators that a slewing bearing may require replacement:
- Unusual Noise:
If you notice grinding, clicking, or any abnormal noises during operation, it could be a sign of wear or misalignment in the slewing bearing.
- Increased Vibration:
Excessive vibration or shaking during rotation could indicate misalignment, damage, or uneven wear in the slewing bearing.
- Irregular Movement:
If the machinery exhibits irregular or jerky movement instead of smooth rotation, it might be due to a damaged slewing bearing.
- Uneven Load Distribution:
Uneven distribution of loads can lead to accelerated wear on specific sections of the bearing, causing premature failure.
- Abnormal Heat Generation:
If the slewing bearing becomes excessively hot during operation, it may suggest friction, misalignment, or lack of proper lubrication.
- Excessive Play or Clearance:
Too much axial or radial play in the bearing can indicate wear, misalignment, or component fatigue, requiring inspection and potential replacement.
- Leakage of Lubricant:
If lubricant leaks from the bearing or seals, it may signify damage to the sealing mechanism or an internal issue that needs attention.
- Visible Wear or Damage:
Inspect the bearing for visible signs of wear, corrosion, pitting, or other forms of damage. Cracks, dents, or deformation are clear indicators of potential problems.
- Reduced Performance:
If the machinery’s performance deteriorates, such as decreased rotation speed, reduced load capacity, or increased power consumption, it could be due to a failing slewing bearing.
- Increased Maintenance Frequency:
If you find yourself needing to perform more frequent maintenance or repairs on the bearing, it might indicate that the bearing is nearing the end of its service life.
- Manufacturer’s Service Life:
Consult the manufacturer’s guidelines for the expected service life of the slewing bearing. If the bearing is approaching this limit, it’s advisable to consider replacement.
If any of these signs are observed, it’s important to consult with experts and consider replacing the slewing bearing to prevent further damage and ensure the safe and efficient operation of machinery.
