Few things are more frustrating than lowering the stylus onto a record—only to watch the tonearm skate inward or skip uncontrollably across the groove. This problem is common, especially with new setups or recently adjusted turntables, and it’s almost always fixable.
Understanding why a tonearm skips or slides inward helps you correct the issue quickly and protect both your records and stylus.
What Does “Sliding Inward” Mean?
When a tonearm slides inward, it moves rapidly toward the center of the record instead of settling into the groove. Skipping may occur at the beginning of a track or repeatedly during playback.
These behaviors indicate a tracking or setup imbalance rather than a damaged record.
Common Causes of Tonearm Skipping or Inward Sliding
1. Incorrect Tracking Force
Tracking force that’s too light is the most common cause.
Why it happens:
The stylus doesn’t have enough downward force to stay seated in the groove.
Fix:
- Set tracking force to the cartridge manufacturer’s recommended range
- Use a stylus force gauge for accuracy
Err on the heavier end of the recommended range rather than too light.
2. Anti-Skate Misadjustment
Anti-skate counteracts the natural inward pull on the tonearm.
Too much anti-skate:
Can cause the arm to slide outward or skip inconsistently.
Too little anti-skate:
Allows the arm to rush inward.
Fix:
- Start with anti-skate set to match tracking force
- Fine-tune by listening or observing stylus behavior
3. Turntable Not Level
A slight tilt can dramatically affect tonearm behavior.
Fix:
- Use a bubble level on the platter
- Adjust feet or platform until perfectly level
- Recheck after moving the turntable
Gravity always wins.
4. Dirty or Damaged Stylus
Debris on the stylus prevents proper groove contact.
Fix:
- Clean the stylus with a proper stylus brush or cleaner
- Inspect for damage using magnification
A worn or bent stylus should be replaced immediately.
5. Faulty or Sticky Tonearm Bearings
Tonearm bearings should move freely with minimal resistance.
Fix:
- Gently test tonearm movement with anti-skate off
- Look for stiffness or hesitation
- Seek professional service if resistance is felt
Never lubricate tonearm bearings yourself.
6. Incorrect Cueing Height or Lift Platform
If the cueing platform doesn’t fully lower, the stylus may barely touch the record.
Fix:
- Ensure the cueing lever lowers completely
- Adjust cueing height if possible
Partial contact leads to skipping.
7. Warped or Dirty Records
Severe warps or heavy contamination can cause repeated skipping.
Fix:
- Clean records thoroughly
- Test with a known flat record
If the issue happens on all records, the problem is likely setup-related.
How to Diagnose the Problem Step-by-Step
- Check that the turntable is level
- Verify tracking force with a gauge
- Set anti-skate correctly
- Clean the stylus
- Observe tonearm movement without a record
Work through these steps in order.
What You Should NOT Do
- Don’t increase anti-skate excessively to stop skipping
- Don’t play records repeatedly while skipping
- Don’t assume the cartridge is defective
- Don’t force the tonearm into place
These actions can damage your stylus and records.
Preventing Skipping in the Future
- Recheck setup after moving the turntable
- Clean stylus and records regularly
- Use proper tracking force
- Avoid cheap or damaged records
Good habits prevent recurring issues.
Final Thoughts
Tonearm skipping or sliding inward is almost always a setup issue—not a fatal flaw. With proper leveling, correct tracking force, and balanced anti-skate, a tonearm should track smoothly and stay locked in the groove.
Fix the cause, not the symptom, and your records—and stylus—will thank you.
