Castellini Silent Power Evo Model Identification
Castellini’s Silent Power Evo / Goldspeed Evo brochure lists Silent Power Evo 4L, 4L K, Miniature, Miniature K, 2L and 2. It describes ceramic ball bearings in the original Evo turbines, but does not provide a loose-bearing size or a cross-reference to our product codes. Use the full instrument and turbine markings to start a part-specific review.
| Marking to identify | Instrument family | What to send for part review |
|---|---|---|
| Silent Power Evo 4L / 4L K | Evo air turbine variants listed by Castellini | Complete marking, turbine reference, removed bearing code and position |
| Silent Power Evo Miniature / Miniature K | Evo miniature turbine variants | Exact miniature version, turbine reference, bearing code and position |
| Silent Power Evo 2L / 2 | Evo air turbine variants | Complete model, turbine reference, bearing code and position |
| Goldspeed Evo M5-L and other handpieces | Separate contra-angle or handpiece family | Exact model and assembly; do not use an Evo turbine bearing map |
For older markings such as Silent Power Gold, Silver or CleanAir 2000, send the complete instrument and turbine identifiers. The Evo brochure is not a loose-bearing interchangeability chart for those names. A nominal size, ceramic-ball description or similar photo does not confirm fit.
For an item-specific quote, include front/rear position, legible old-bearing code, clear photos, quantity and destination. Browse dental bearings and high-speed bearing options, then send the exact identifiers for review.
Why the Exact Castellini Turbine Matters
Castellini describes ceramic ball bearings in its original Silent Power Evo turbines. That description does not establish the material, cage, tolerance, lubricant or acoustic performance of a replacement offered on this site. Matching a nominal bearing size alone is not enough to validate a particular rotor assembly.
Noise, vibration or loss of torque can also involve the rotor, chuck, air supply, bearing seating and other parts. A qualified repair assessment should identify the exact turbine and both bearing positions before choosing parts. Follow the applicable Castellini instructions for maintenance and reprocessing; we do not infer a universal sterilization limit for a replacement bearing.

Request a Castellini Bearing Identification and Quote
Send the complete Castellini model marking, turbine or rotor reference, removed bearing code and front/rear position. Add clear photos, required quantity and destination. We will check the proposed part drawing and scope, then reply with a quote or specific information still needed to identify the bearing.
Castellini Handpiece Bearing FAQ
Do your bearings fit Silent Power Evo 4L or 4L K?
No universal fit has been established for the parts on this page. Castellini’s brochure identifies Silent Power Evo 4L and 4L K as instrument variants and describes ceramic bearings in the original turbine, but does not give a loose-bearing cross-reference to our SKU. Send the exact turbine marking, removed bearing code and position so we can compare the proposed part drawing.
Do Silent Power Gold or Silver use the same bearing as Evo?
Do not assume interchangeability across Silent Power Gold, Silver and Evo versions. The current Evo brochure identifies the Evo family, not a loose-bearing cross-reference for these other markings. For an older turbine, provide its exact model, rotor or cartridge reference and removed bearing details. We will state whether a specific candidate can be verified before quoting.
Can I order loose bearings or a complete Castellini turbine?
This Hub accepts requests for individual bearing identification and quotation. If you need a complete turbine or cartridge instead, include that request and the exact assembly reference. Availability, supplied scope and compatibility must be confirmed for the specific item; a bearing replacement alone is not a promise to restore original instrument specifications.
Will replacing bearings fix noise or loss of torque?
Not necessarily. Worn bearings are one possible cause, but rotor damage, chuck condition, air supply and seating may also affect speed, noise and torque. Have the complete turbine assessed against the correct instrument instructions. Send the model, symptoms, turbine reference and removed bearing details for a part-specific review.
