Référence: DLG00239
Marathon Saeyang micromotor chuck 2.35 mm
The 2.35 mm Marathon micromotor chuck is an essential replacement part to restore reliable bur retention, improve rotational stability and ensure safer operation in the dental laboratory. It fits common Saeyang / Marathon configurations and is notably used as a replacement part for the C1 Plus D.L.G micromotor.
A small part that directly affects handpiece precision
In a dental laboratory, a 2.35 mm micromotor chuck in good condition directly contributes to stable rotation, secure bur retention and safe handpiece operation. When the chuck becomes worn, deformed or fatigued, tightening becomes less consistent, bur changes may become less precise and overall working comfort drops significantly.
Key advantages in the laboratory
- Precise bur tightening to reduce play during operation.
- Easy replacement when the original collet starts losing efficiency.
- 2.35 mm format suited to rotary instruments commonly used in dental prosthetic work.
- Strategic wear part for maintaining clean and safe operation.
- Steel construction for stable mechanical performance.
Compatibility and use
- Compatible with Saeyang / Marathon systems depending on handpiece configuration.
- Suitable for Strong 210 models.
- Intended for Forte 210 – 102L – 105L handpieces.
- Designed for 2.35 mm instrument shanks.
- Recommended replacement in case of irregular tightening or visible mechanical wear.
Dental and technical applications
This dental micromotor chuck is intended for workstations requiring smooth rotation and reliable bur retention: resin adjustment, finishing work, precision corrections, appliance trimming and routine laboratory refinements.
On a handpiece used every day, chuck quality directly influences control, instrument safety and the consistency of the operator’s movements.
Replacement and precautions
Replacement should ideally be carried out by a professional, unless you are already familiar with the procedure. Place the key on the chuck head, unscrew the old part, then install the new one without applying inappropriate external pressure to the collet.
Correct installation helps restore clean operation and prevents damage to the new chuck during fitting.

Frequently asked questions
Is this chuck compatible with a Strong 210 micromotor?
Yes, this 2.35 mm micromotor chuck is presented as compatible with Strong 210 type configurations, as well as handpieces such as 102L and 105L. It is still recommended to check the exact compatibility with your handpiece before installation, especially if your equipment has already received replacement parts in the past.
What exactly is the function of the chuck in a Marathon handpiece?
The chuck, also called a collet depending on terminology, ensures the tightening of the bur inside the handpiece. It must hold the instrument securely in order to guarantee smooth rotation, precise work and good operating safety in the dental laboratory.
When should a micromotor chuck be replaced?
It is advisable to replace the chuck when you notice less reliable tightening, slight bur play, difficulty when changing instruments or visible wear on the part. On an intensively used workstation, this small maintenance step often helps restore cleaner operation very quickly.
Is replacement difficult?
No, the procedure is generally straightforward for an experienced user. However, you should work carefully, use the correct key, remove the old chuck without forcing it and avoid tightening the new part improperly from the outside. If in doubt, professional replacement remains the safest option.
