Shimadzu Option Parts Axial MB2 Assembly V2304 for TMP-V2304 Series Molecular Pump

The Shimadzu Option Parts Axial MB 2 Assy V2304 is a precision axial electromagnetic assembly designed specifically for the TMP-V2304 series turbo molecular pumps. This assembly (often called the axial magnetic bearing coil or axial electromagnet unit) provides controlled axial force to stabilize the rotor, maintain axial position under varying loads and speeds, and ensure reliable high-vacuum performance in laboratory and industrial vacuum systems.

Key features

• Direct fit for TMP-V2304 series — engineered to the same mechanical interfaces and electrical characteristics as the factory original.
• High-precision winding and insulation to maintain stable electromagnetic response and long service life.
• Optimized for low thermal drift and minimal outgassing when used inside high-vacuum environments.
• Robust connector and mounting points for straightforward replacement and reliable mechanical coupling.

Technical overview

The Axial MB 2 Assy V2304 is an electromagnet assembly that exerts axial force on the rotor or axial bearing element. Typical functional roles include axial centering during high-speed operation and transient compensation during start/stop cycles. The assembly is manufactured to tight tolerances to preserve rotor balance and to avoid introducing eccentric loads or magnetic imbalances that could affect pump vibration or lifetime.

Compatibility

Specifically designed for the TMP-V2304 series molecular pumps. If you are servicing or rebuilding a TMP-V2304, this assembly is the correct option part for axial magnetic support. For related option parts and maintenance components see the supplier's non-standard parts listings: Shimadzu molecular pump non-standard parts, non-standard maintenance parts, and additional Shimadzu Option Parts resources available from the same collection: Shimadzu Option Parts.

Installation notes

• Work in a clean, ESD-safe environment. Avoid particulate contamination of the magnetic surfaces and bearing area.
• Follow torque specifications for mounting screws to ensure correct axial preload; uneven torque may introduce rotor imbalance.
• Confirm electrical connector pinout and insulation resistance before powering the unit. Use the pump’s service manual for wiring diagrams.
• After installation, perform a controlled spin-up and monitor axial position signals and vibration; adjust controller gains if required per pump OEM procedures.

Maintenance and troubleshooting

• Periodic inspection: check for discoloration, winding insulation damage or connector corrosion during routine pump service.
• Common failure symptoms: unexpected axial drift, increased vibration at low speeds, or fault codes from axial position sensors may indicate a failing electromagnet assembly.
• Replacement: if the coil assembly shows electrical leakage, open winding faults, or physical deformation, replace the assembly rather than attempting field rewinding.

Ordering, packaging and support

This Option Part is supplied as a ready-to-install assy. Orders typically include the axial MB 2 unit and standard mounting hardware unless otherwise specified.

Safety and handling

• De-energize and isolate the pump before performing any replacement.
• Beware of magnetic fields during handling — keep magnetic media and ferrous tools at a safe distance to avoid attraction and damage.
• Dispose of replaced components according to local electronic-waste regulations.
