Shimadzu Option Parts SHAFT ASSY 1303LM for TMP-1303-1503 Series Molecular Pump

This listing describes the Shimadzu Option Parts SHAFT ASSY 1303LM — the rotating main shaft designed as an original repair part for TMP-1303 and TMP-1503 series molecular pumps. Manufactured to the original equipment specifications, this shaft assembly restores precise rotational alignment, dynamic balance and long-term reliability in affected turbo molecular pump rotors.

Key Characteristics

• Direct replacement shaft assembly specifically for TMP-1303 and TMP-1503 series molecular pumps.
• OEM-quality manufacturing tolerances for concentricity, runout and surface finish to maintain rotor balance at high speed.
• Designed for the rotating main shaft position — critical for rotor stability and bearing load distribution.
• Supplied as a repair/original part to simplify maintenance and minimize risk of damage to adjacent components.

Compatibility

Compatible with TMP-1303 and TMP-1503 series molecular pumps. Confirm pump serial and model before ordering to ensure fitment. For related maintenance parts and non-standard repair components, see Shimadzu molecular pump non-standard maintenance parts for parts commonly used in overhaul kits.

Materials & Manufacturing

The shaft assembly is produced from high-strength, wear-resistant metals and undergoes precision turning, grinding and balance correction processes. Surface finishing and critical dimension inspection ensure minimal micro-imbalance and correct seating with bearings and seals.

Installation & Service Notes

1. Only qualified service personnel should perform shaft replacement. Follow the pump manufacturer’s service manual and safety procedures.
2. Disassemble the rotor/bearing assembly carefully to avoid contamination and mark component orientation for reassembly.
3. Inspect bearings, seals and mating surfaces; replace any worn items. Installing a new shaft into worn bearings can accelerate failure.
4. After installation, perform dynamic balancing and run-in checks at low speed, gradually increasing to rated speed while monitoring vibration and temperature.
5. Keep the work area clean and use proper tools to avoid introducing nicks or debris that could affect balance and sealing.

Inspection & Maintenance Recommendations

• Check shaft journal surfaces for scoring and polish if minor; replace if out of tolerance.
• Monitor bearing wear and vibration trends after replacement so that any residual imbalance can be identified early.
• Store replacement shafts in clean, dry packaging to prevent corrosion and distortion before use.

Quality Assurance

Each SHAFT ASSY 1303LM is subject to dimensional and balance inspection prior to shipment. Replacement with an OEM-quality shaft helps restore pump performance and extends service intervals when combined with proper bearing and seal replacement.

Ordering & Spare Recommendations

When planning pump overhauls, order shaft assembly along with bearings and seals as a kit to ensure a complete, reliable repair.
