Axial MB 1 Assy for TMP 2003 3603 Series

This listing describes the Axial Magnet Bearing (1) Assembly — an OEM repair component designed for Shimadzu TMP-2003 / TMP-3603 series turbomolecular pumps. It is an exact-fit axial magnetic bearing used in the rotor support and magnetic suspension system of TMP-3003~3603 series pumps, manufactured to the original specifications to restore bearing function, minimize vibration, and ensure long-term reliability.

Key features at a glance:

• Function: Axial magnetic bearing element that controls axial position and stability of the rotor within the turbomolecular pump.
• Compatibility: Specifically for TMP-2003 and TMP-3603 series pumps (also referenced as TMP-3003~3603 series repair parts).
• Type: OEM / original parts repair assembly intended to replace worn or damaged axial magnetic bearing components.
• Condition: New or factory-refurbished OEM component depending on supplier stock; inspected and matched to original tolerances.

Typical benefits when replacing the axial MB assembly:

• Restores proper axial levitation and centering of the rotor to factory tolerances.
• Reduces axial runout and precession, improving pumping efficiency and life span.
• Prevents contact-related wear between rotor and stator components, protecting costly rotor assemblies.
• Helps eliminate vibration-induced failures and electronic control anomalies tied to bearing degradation.

Technical considerations and installation notes:

• Pre-install inspection: verify the assembly is free of particulate contamination, physical damage, and that connectors/mounting faces are clean and flat.
• Alignment: axial bearings must be reinstalled with precise axial and radial alignment; follow the pump manufacturer’s alignment procedure and torque specifications for fasteners.
• Handling: avoid strong magnetic fields during handling and keep the part in anti-static, clean packaging until installation.
• Testing: after installation, perform rotor levitation and control-loop verification using the pump controller diagnostics; monitor vibration and bearing current for stable operation before returning the pump to service.

Common signs that the Axial MB 1 Assy may need replacement:

• Increased axial vibration or rotor axial drift detected during run-up.
• Unstable bearing control currents or frequent bearing fault alarms from the pump controller.
• Unusual noise, intermittent contact events, or degraded ultimate pressure.
• Visual inspection reveals wear, scoring, or contamination on bearing surfaces.

Quality and authenticity:

• This assembly is intended as an original repair part built to the same mechanical and magnetic specifications used in the TMP-2003 / TMP-3603 family of turbomolecular pumps. Use of OEM components ensures the original dynamic balance and control performance of the pump.
• For verified OEM maintenance parts and non-standard repair components, review the official parts listing and availability: Shimadzu molecular pump non-standard maintenance parts.

Ordering and spare management:

• When ordering, confirm your pump model and serial number to ensure the correct axial MB assembly variant is supplied. Some runs may require matched sets or revision-specific parts.
• Keep spare axial bearing assemblies on hand for critical tools to minimize downtime during maintenance.
• For part procurement and additional related components, consult the OEM parts index: Shimadzu molecular pump non-standard maintenance parts.

Related maintenance items to consider when replacing the axial bearing:

• Rotor balancing check and dynamic balancing if rotor weights or balance markers are disturbed.
• Inspection and possible replacement of radial support bearings, seals, and motor couplings.
• Cleaning or replacement of electronic sensors and cabling associated with the magnetic bearing controller.
