How To Enhance The Use Effect Of Slewing Bearings

What Are Slew Bearings?

Slewing bearings are the essential parts of heavy industrial machinery—think cranes lifting steel beams, excavators digging construction sites,  or port gantry cranes moving shipping containers. These large-scale machines rely on slewing bearings to handle massive loads while enabling smooth, precise rotation. in order to better use the bearing , We need to pay attention to the following aspects.

How Do You Resolve the Common Issues That Occur During the Operation of Slew Bearings?

Most problems during operation stem from a few key areas. Being proactive here dramatically extends bearing life.

   1. Problem: Abnormal Noise & Vibration. 

         You might hear a periodic "clunking" or feel unusual shudders during rotation.                                                             

• Why it happens: This is often a distress signal. It's usually caused by wear or damage inside the bearing raceway. The culprits are often poor lubrication (leading to metal-on-metal contact), contamination (dirt acting as grinding paste), or uneven load distribution from an improper initial installation.

• What to do: Don't ignore the warning. First, check the lubrication. Is there enough grease? Is it clean? A scheduled re-lubrication with the correct, high-quality grease can often prevent this. Second, ensure seals are intact to keep contaminants out. If the issue persists, a professional inspection is needed to assess internal wear.

   2. Problem: Rough or Stiff Rotation. 

         The machinery feels sluggish, requires more power to turn, or has tight spots.

• Why it happens: This points to increased internal friction. The most common reasons are contamination (sand, grit), corrosion from moisture, or a lack of lubrication. In severe cases, it could be due to misalignment putting the bearing under constant stress.

• What to do: Focus on sealing and environment. Regularly clean the area around the bearing seals to prevent debris buildup. In wet or corrosive environments, inspect more frequently for rust and consider using corrosion-resistant bearings. Consistent, correct lubrication is your best defense to keep rotation smooth.

    3.  Problem: Seal Failure & Lubricant Leaks. 

          You see grease leaking out or find contaminants/water inside.

• Why it happens: Seals degrade over time due to weather, UV exposure, or physical damage. Failed seals let the good grease out and the bad stuff in, starting a rapid cycle of wear.

• What to do: Make seal inspection a part of routine maintenance. Look for cracks, tears, or deformation. Keep them clean. Choosing a bearing with a robust, multi-layered seal design from the start pays off in the long run.

  4.  Problem: Connection Bolt Loosening.

        This is a critical safety and performance issue.

• Why it happens: It's often due to vibration, insufficient tightening during installation, or a flexible supporting structure that flexes under load.

• What to do: During installation, always follow the manufacturer's procedure: use a torque wrench and tighten in a cross-bolt pattern in stages. After the first 100 hours of operation, re-tighten all bolts, as this is when settling occurs. Establish a schedule for periodic bolt checks.
