Learn how to diagnose and fix a loose steel ball in your eitech slewing ring. Step-by-step repair guide with replacement tips.
Quick answer
If your eitech slewing ring wobbles or binds, the likely cause is a worn or missing steel ball. Replace it with a genuine eitech Ø 6 mm steel ball (16-piece set, SKU 01467) to restore smooth operation.
Why steel balls matter in a slewing ring
A slewing ring uses small steel balls as rolling elements between two rings. They distribute load and allow smooth rotation. If a ball is lost or deformed, the ring will feel loose, catch, or bind during movement.
When to replace vs. when to rebuild
Replacing a single loose ball is quick and works if the ring and raceway are undamaged. If the ring itself is cracked or the raceway is badly worn, you may need to replace the entire slewing ring assembly. Inspect carefully before ordering parts.
Diagnosis and repair steps
- Symptom: The slewing ring wobbles, catches, or has uneven resistance when rotated. You may hear a clicking sound.
- Likely cause: One or more Ø 6 mm steel balls are missing, flattened, or have shifted out of the raceway. Stop using the model until repaired to avoid damaging the raceway further.
- Corrective action: Disassemble the slewing ring carefully. Retrieve any loose balls and inspect the raceway. Replace missing or damaged balls with new eitech Ø 6 mm steel balls. Reassemble and test rotation. If the raceway is scored or cracked, replace the entire slewing ring instead of just the balls.
- When to stop: If you cannot find replacement balls or the raceway shows visible damage, stop and order a new slewing ring assembly. Do not force the ring back together.
