Morita TwinPower 4H Models and Cartridge References
The J. Morita TwinPower Turbine 4H instructions (2026) identify separate PAR models and complete replacement cartridges. The references below are Morita cartridge codes, not loose-bearing cross-references. Confirm the complete model and coupling suffix before any part inquiry.
| TwinPower 4H model | Morita replacement assembly in IFU | Identification step |
|---|---|---|
| PAR-4HEX | Capsule cartridge, code 5010862 | Confirm complete model and coupling suffix |
| PAR-4HX | Capsule cartridge, code 5010863 | Confirm complete model and coupling suffix |
| PAR-4HEX-45 | Capsule cartridge, code 5011010 | Confirm the 45-degree version and full model |
| PAR-4HUEX | Rotor cartridge with replacement tool set, code 5011147 | Confirm exact Ultra E model and assembly |
| PAR-4HUMX | Rotor cartridge with replacement tool set, code 5011148 | Confirm exact Ultra M model and assembly |
Fit boundary: These manufacturer codes identify complete cartridges. They do not validate an SR144-series loose bearing or any aftermarket part. Morita’s instructions direct use of genuine Morita replacement parts for clinical service.
Cartridge Choice, Coupling Suffix and Bearing Fit
- Identify the exact PAR model. PAR-4HEX, PAR-4HX, PAR-4HUEX, PAR-4HUMX and PAR-4HEX-45 have different service references. Copy any suffix such as KV, NK, ND, WH or SR; it identifies a coupling configuration, not a bearing size.
- Separate cartridge and loose bearing. Morita specifies capsule or rotor cartridge assemblies. The old bearing marking, dimensions and front/rear position may help a technical review, but they do not prove an aftermarket fit.
- Follow the device IFU. Morita directs genuine replacement parts and lists cartridge replacement or professional repair for abnormal rotation, heat, noise, wobble or chuck issues. Do not promise that changing a bearing alone restores the device.
- Request an exact-scope quote. Send the model, coupling suffix, cartridge code, photos, removed part details, quantity and destination. Specify whether you need a complete cartridge or are asking about a loose-bearing candidate.
Morita markets Zero Drawback as a handpiece-system feature. We have no evidence that a replacement loose bearing preserves that function. For broader part selection, see our high-speed dental bearings guide.

Request Morita Part Identification and Quote
Send the full PAR model, coupling suffix, cartridge code or photo, removed bearing marking if relevant, front/rear position, quantity and destination. Tell us whether you seek a complete cartridge or a loose-bearing candidate. Morita directs genuine parts for clinical service; we will clarify the requested scope and evidence before any quote.
Morita TwinPower 4H Parts FAQ
Can a TwinPower capsule be rebuilt with a generic loose bearing?
Morita’s 2026 TwinPower 4H IFU specifies complete capsule cartridges for PAR-4HEX, PAR-4HX and PAR-4HEX-45 and directs use of genuine replacement parts. It does not validate a generic loose-bearing rebuild. For clinical service, follow the exact model’s IFU and manufacturer repair route.
Does a loose bearing preserve Morita Zero Drawback?
No such claim is verified. Morita describes Zero Drawback as a feature of the complete TwinPower handpiece. A loose bearing’s dimensions or precision class alone cannot establish that the assembled handpiece retains that function. Follow the manufacturer’s cartridge and service instructions.
Are PAR-4HEX and PAR-4HUEX cartridges interchangeable?
Do not assume so. Morita’s IFU lists PAR-4HEX with capsule cartridge code 5010862 and PAR-4HUEX with rotor cartridge code 5011147. The different assembly references do not establish cross-fit. Use the full model and coupling suffix to select the manufacturer-specified part.
What details should I send for a Morita parts quote?
Send the full PAR model and any suffix (for example KV, NK, ND, WH or SR), the cartridge code or clear assembly photos, the removed bearing marking if relevant, the part position, quantity and destination. State whether you need a complete Morita cartridge or a loose-bearing candidate. We will clarify fit evidence, scope and availability before quoting; we do not claim OEM approval for an unverified aftermarket part.
