The Shimadzu Axial Rotor Disk 3003 (Axial Rotor Sensing Disk) is a precision option part designed for TMP-2003, TMP-3003 and TMP-3603 series molecular (turbomolecular) pumps. This component is a critical element of the rotor sensing and balance system — it provides accurate axial position / rotational reference for the pump's sensor assembly and helps maintain stable high-speed operation.

Axial Rotor Disk 3003 (illustrative)
- Compatible Models: TMP-2003, TMP-3003, TMP-3603 series molecular pumps.
- Primary Function: rotor sensing / induction disk that interfaces with the pump’s sensor module for speed/position monitoring and contributes to rotor balance.
- Construction: precision-machined, corrosion-resistant metal (typically stainless steel or similarly hardened alloy) with tight tolerances to ensure concentricity and dynamic balance.
- Condition: OEM-quality option part manufactured to meet Shimadzu pump tolerances and fitment requirements.
Key Features
- Precision radial and axial tolerances for reliable high-speed operation.
- Dynamic balance compatible with TMP-2003 / 3003 / 3603 rotor assemblies.
- Robust surface finish to resist particulate generation and maintain vacuum cleanliness.
- Direct drop-in replacement for corresponding Shimadzu option part specifications.
Typical Specifications
- Part type: Axial rotor sensing/induction disk (Option Part for Shimadzu TMP series)
- Applicable series: TMP-2003, TMP-3003, TMP-3603
- Material: Stainless steel or equivalent corrosion-resistant alloy (manufacturing spec)
- Tolerance: Machined to concentricity and thickness tolerances required for rotor balance (manufacturer controlled)
- Finish: Vacuum-cleaned, deburred and packaged to prevent contamination
Installation & Replacement Notes
- Always power down and isolate the pump before disassembly. Follow Shimadzu service safety procedures for turbomolecular pumps.
- Remove rotor assembly according to the service manual to access the axial sensing disk. Keep work area clean and use lint-free gloves.
- Inspect mating surfaces, sensor clearance, and fasteners. Replace any worn bearings or seals per the pump maintenance schedule.
- Install the Axial Rotor Disk 3003 with correct orientation and torque settings as specified in the service documentation. Verify sensor alignment and air-gap clearance.
- After replacement, perform rotor balance verification (if required), spin test at low speed, and leak/functional tests before returning the pump to service.
Maintenance & Handling
- Inspect the disk for nicks, deformation, or contamination at every major service interval.
- Clean using isopropyl alcohol or approved solvent; avoid abrasive cleaning that could change balance characteristics.
- Store in anti-static, dust-free packaging. Protect edges from impact to preserve concentricity.
- If any signs of imbalance or vibration occur after installation, re-check mounting and clearances; perform dynamic balancing if necessary.
