Shimadzu Option Parts Shaft Assembly For 3304 TMP 3304 Series Molecular Pump

Product Overview

The Shimadzu Option Parts Shaft(S) ASSY for 3304 is a precision replacement shaft assembly designed specifically for the TMP-3304 series molecular pumps. Manufactured to meet strict dimensional and cleanliness requirements, this shaft assembly restores the rotating spindle and associated interfaces to factory performance, ensuring stable high-vacuum operation and long service life.

Key Features

• Direct fit for TMP-3304 series molecular pumps (OEM-style form, fit and function)
• High-quality stainless steel shaft material with precision-machined journals
• Balanced and inspected for vibration-free rotation at rated speeds
• Supplied clean and ready for installation to minimize contamination risk
• Manufactured and inspected under controlled conditions for repeatable performance

Materials & Manufacturing

The Shaft(S) ASSY is produced from corrosion-resistant, vacuum-compatible metals and finished to tight surface tolerances. Critical bearing surfaces and mating features are machined and ground, then dimensional inspection and dynamic balancing are performed to ensure concentricity and minimal runout. Parts are cleaned, packed in protective packaging and labeled for traceability.

Compatibility

Intended explicitly for the TMP-3304 series molecular pump family. Use this assembly when diagnosing shaft-related failures such as excessive vibration, unusual bearing noise, or mechanical damage to the rotor/stator interface. Always verify pump serial/model before ordering replacement parts.

Installation & Handling Recommendations

• Follow the Shimadzu service manual procedures for disassembly and reassembly. If in doubt, contact qualified service personnel.
• Handle the shaft assembly with clean gloves to prevent contamination of bearing journals and sealing surfaces.
• Avoid impact, bending or axial shocks during installation; the assembly is precision-balanced and can be damaged by rough handling.
• Use only specified lubricants or bearing elements recommended by the pump manufacturer; do not introduce oils or greases that are incompatible with high-vacuum systems.
• After installation, perform a dry-spin-up and vibration check before returning the pump to service.

Quality Assurance & Testing

Each Shaft(S) ASSY undergoes visual inspection, dimensional verification and dynamic balancing. Where applicable, parts are run-tested off-pump to verify free rotation and to detect any residual imbalance. Certificates of inspection and lot traceability can be provided on request.

Packaging & Shipping

Parts are individually packaged in clean, anti-corrosive and shock-protective materials. Special packaging options for long-term storage or international shipment are available. Lead times depend on stock and order volume; please inquire for current availability.
