MT-2122 Automatic Spring Separator Machine — Universal Valve & Clutch Spring Compressor

MRO HAND TOOL · MECHANICAL SPRING COMPRESSOR · ADJUSTABLE JAW

The MT-2122 is a universal automatic spring separator machine built for safely compressing cylindrical and tapered (conical) springs during assembly and disassembly. While KOEED is best known as a multi-brand industrial automation spare parts distributor covering Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE, we also source the mechanical MRO hand tools that the same maintenance teams need on the shop floor. The MT-2122 belongs to that adjacent MRO category — the kind of tool your technician reaches for before swapping out a servo amplifier, a pneumatic actuator or a CNC spindle spring.

Key Technical Specifications

Application Scenarios — Where the MT-2122 Fits

The MT-2122 is the workhorse tool you keep on the bench next to your PLC spares cabinet. The maintenance crews who service Allen-Bradley ControlLogix racks, Siemens SIMATIC S7-300 backplanes, Mitsubishi MELSEC I/O, Omron SYSMAC stations, Fanuc CNC servos, Schneider Modicon chassis, Yaskawa Sigma-7 drives, Panasonic FP controllers and KEYENCE vision systems all eventually need to compress a stubborn return spring. Typical fit-for-purpose scenarios include:

• Automotive & heavy-vehicle workshops — removing and installing valve springs and clutch diaphragm springs during engine rebuilds.
• Industrial valve maintenance — compressing tapered springs inside process control valves used on chemical, water-treatment and food-and-beverage lines.
• Hydraulic & pneumatic cylinder service — safely releasing large return springs during seal replacement on hydraulic cylinders.
• Suspension & drivetrain — disassembly of conical coil springs on light-commercial suspensions and CV-joint assemblies.
• CNC and large machinery — supporting spring changes on equipment that also runs Fanuc, Siemens Sinumerik or Mitsubishi M80 controllers; technicians can perform mechanical work while PLC swap-out is staged.
• General MRO shop floor — any time a strong coiled spring needs controlled compression before fasteners or keepers can be accessed.

Integration & Wiring Notes

Because the MT-2122 is a purely mechanical tool, it has no electrical interface, no fieldbus node, no EtherNet/IP or Profinet footprint, and no I/O assignment to map against your Allen-Bradley ControlLogix program or your Siemens SIMATIC S7 project. There is nothing to wire, no IP address to assign, and no firmware to flash. From a controls-engineering standpoint, it is invisible on the network diagram.

The practical “integration” consideration is shop-floor logistics: where you store the tool, how it is logged out, and which maintenance crews have access. Most plant teams barcode the MT-2122 alongside their PLC spares and assign it to the same tool crib that dispenses Mitsubishi MR-J4 servo cables, Omron CP1E spares, and KEYENCE sensor replacements. Because the tool is non-electrical, it can be safely used inside energized control cabinets, near PLC backplanes, and around live servo amplifiers — provided standard lock-out / tag-out procedures are followed for the equipment being serviced.

For sites that track tool inventory inside a CMMS or KOEED AI Diagnostic Tool workflow, the MT-2122 can be added as a non-consumable asset with a simple model number reference. The lack of wiring also means no EMC, CE-RED, or UL-listing concerns that would otherwise apply to a connected Schneider Altivar drive or a Yaskawa Sigma-7 servo.

Installation & Commissioning Tips

• Inspect the jaws before each use. Check for cracks, mushroomed tips, or bent hooks. A damaged jaw can slip off a compressed spring and release stored energy suddenly — the most common injury cause with any spring separator.
• Match jaw geometry to spring type. Use the wider hook setting for straight cylindrical springs; switch to the narrower tapered setting for conical valve springs. Forcing the wrong hook profile can damage both the spring and the tool.
• Compress in stages. Apply the leverage smoothly, a quarter-turn at a time, and pause to confirm the spring keepers (collets, retainer caps) are clear before going further.
• Work on a stable surface. The MT-2122 is a one-person tool, but the assembly you are working on should be firmly clamped in a vice or fixture. Free-floating parts can shift as the spring unloads.
• Wear eye protection. Always. Compressed springs store significant energy, and even a small spring can launch a keeper across a workshop if the tool slips.
• Keep the tool lightly oiled. A drop of light machine oil on the pivot points and threads every few months keeps the leverage action smooth and prevents rust on the jaws.
• Coordinate with the controls team. When the spring work overlaps with a PLC, servo, or HMI swap, list the MT-2122 on the same work-order ticket so the Fanuc or Panasonic technician knows the mechanical side of the job is covered.

Procurement, Warranty & Lead Time

KOEED is a China sourcing company that supplies industrial automation spare parts for the nine brands above. The MT-2122 sits in our MRO / hand-tool line, so it is typically quoted and dispatched on the same order that includes your PLC, HMI, or servo parts. We do not publish fixed unit pricing on this page; instead, every order is handled as an RFQ so we can confirm the current production batch, packaging configuration (single unit, 5-pack, or tool-cabinet kit) and freight terms to your country.

Send the model number MT-2122, the quantity you need, and your delivery city to Moritta@KOEED.COM and you will receive availability plus a freight-inclusive quote within 24 business hours. If the MT-2122 is part of a larger maintenance rebuild, attach the rest of the BOM — including any Allen-Bradley 1756 or Siemens 6ES7 modules on the same work order — and we will quote the lot in a single response. Larger tooling rollouts (full workshop outfit, multi-site standardization) can be coordinated through the Create a Quote form.

Standard warranty terms follow our published Return Policy and Shipping Policy. Worldwide shipping is available through DHL, FedEx and UPS; typical lead time from order confirmation to dispatch is 3–7 business days for in-stock units, longer for special packaging or large-volume orders. For urgent breakdowns, flag the email subject line with URGENT and we will prioritize. The Real-Time Records page shows recent dispatch activity if you want to see current throughput before ordering.

Engineers who source the MT-2122 alongside their Mitsubishi MELSEC or Omron SYSMAC spares from KOEED benefit from a single point of contact, a single freight invoice, and a single warranty path. To learn more about the company behind the supply chain, visit the About KOEED page or read the latest entries on the Daily PLC News blog. For anything that is not on this page — special spring sizes, custom kits, or non-standard packaging — email Moritta@KOEED.COM directly and we will source it.

The MT-2122 is a mechanical hand tool supplied alongside KOEED’s core industrial-automation line. It is not a PLC, HMI, drive, or sensor, and is not affiliated with Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic or KEYENCE.
