Bien-Air Model References: Identify the Instrument First
Bien-Air’s own documentation distinguishes these instrument variants. The references below identify complete handpieces, not replacement bearings or an interchange chart.
Manufacturer device references, not bearing codes. Bien-Air’s Bora/Prestige instructions for use and CA 1:5 product page list distinct instruments:
- Bora air turbines: Bora 1600381-001, Bora L 1600382-001 and Bora LK 1600732-001. The manufacturer lists Bora/Bora L with a Unifix coupling and Bora LK with an LK 4HL coupling.
- Prestige air turbines: Prestige 1600379-001, Prestige L 1600380-001 and Prestige LK 1600734-001. Preserve the complete suffix and reference in an inquiry.
- CA 1:5 contra-angles: CA 1:5 Standard 1600325-001 and CA 1:5 L Standard 1600386-001. These are separate electric attachments; a turbine bearing list does not establish their bearing fit.
These manufacturer references identify the instruments in the cited sources. They are not replacement bearing numbers or proof that one bearing fits multiple variants. Copy the marking on the actual instrument and assembly.
What to send for a part review
- Full instrument model: Include every letter, suffix and visible manufacturer reference.
- Assembly and position: Identify the turbine, contra-angle head or other replaceable assembly, and front or rear bearing position if known.
- Removed bearing: Copy its complete marking and photograph both faces if the code is worn.
- Proposed item evidence: Request its exact part code, drawing or specification and a direct fit reference for the specific assembly. A similar nominal size alone cannot confirm interchangeability.
- Quote details: Send quantity and destination country; ask for documented fit scope, availability and written terms.
For broader navigation, see our dental bearings guide, high-speed bearing category and low-speed bearing category. Category membership alone does not establish Bien-Air fit.
Verify Bearing Fit and Repair Scope
- Air turbines: Confirm the full Bora, Prestige or Tornado model and turbine reference. Compare the removed bearing and proposed item against an item-specific drawing and a direct fit reference for that exact assembly.
- Electric contra-angles: Treat CA 1:5 and its variants separately from air turbines. Check the exact head or attachment reference, bearing position, construction, lubrication and device service instructions before selecting a candidate.
Bien-Air model names support part identification; they do not mean Bien-Air manufactured or endorsed a proposed replacement bearing.

Bien-Air Handpiece Bearing FAQ
Do Bora, Bora L and Bora LK use the same bearing?
Do not assume that they do. Bien-Air lists Bora (1600381-001), Bora L (1600382-001) and Bora LK (1600732-001) as different turbine references; the LK version also has a different coupling. These are instrument references, not bearing codes. Check the exact turbine and proposed bearing documentation before ordering.
Which bearing fits a Bien-Air CA 1:5 contra-angle?
The CA 1:5 is a contra-angle, not a Bora or Prestige air turbine. Bien-Air lists CA 1:5 Standard (1600325-001) and CA 1:5 L Standard (1600386-001) as instrument references. Neither reference identifies a replacement bearing. Send the exact attachment marking, old bearing code and position for an item-specific fit review.
Does a Bien-Air Tornado turbine use the same bearing as Bora?
A shared brand or similar nominal size does not establish interchangeability. Send the complete Tornado model, turbine assembly reference, old bearing marking and position. Ask for an item-specific drawing and direct fit evidence for the proposed bearing.
Will a bearing replacement fix noise in a Bien-Air handpiece?
Noise or vibration can have causes beyond the bearing, including the rotor, chuck, drive or air supply. Inspect the complete instrument under the applicable manufacturer service instructions. Confirm the failed component and exact replacement reference before ordering.
