What Our SEISA Repair Services Include

A PARAMAX repair begins with a detailed evaluation of the gearbox and its internal components. The final scope depends on the condition of the unit, the application, and the inspection findings.

1. Unit Identification and Service Review

The SEISA model, ratio, shaft arrangement, mounting configuration, application, operating symptoms, and available service history are reviewed before the repair scope is developed.

2. Complete Disassembly and Inspection

The gearbox is carefully disassembled and its components are cataloged so gearing, bearings, seals, shafts, housings, bases, and internal surfaces can be evaluated.

3. Internal Component Evaluation

Gears, bearings, shafts, and related components are checked for pitting, cracking, scoring, wear, distortion, and hidden defects.

4. Component Repair and Manufacturing

The repair may include bearing and seal replacement, shaft restoration, housing work, machining, or gear manufacturing based on the condition of the unit.

5. Precision Reassembly and Testing

The SEISA gearbox is reassembled to the approved repair scope, with gear contact, backlash, shaft movement, sealing, and applicable clearances checked before testing.

6. Reporting and Field Support

Support may include documented findings, repair recommendations, on-site evaluation, installation assistance, alignment, commissioning, and start-up support.

Support for Aging and Installed SEISA Gearboxes

✓ Identification of Older Units

Nameplate details, drawings, photos, service records, and physical inspection can help identify older or hard-to-document SEISA gearboxes.

✓ Inspection of Critical Components

Gearing, bearings, shafts, housings, seals, lubrication components, and internal surfaces can be evaluated for wear or damage.

✓ Review of Prior Repairs and Modifications

Earlier repairs, replacement components, field modifications, and operating changes are considered when the repair scope is developed.

✓ Repair, Rebuild, or Replacement Guidance

Inspection findings help determine whether the unit should be repaired, rebuilt, supported with manufactured components, or reviewed for replacement.

SEISA Gearbox Repair FAQs

Find answers about identifying, inspecting, repairing, rebuilding, and replacing aging or installed SEISA gearboxes.

Can Sumitomo repair older SEISA gearboxes?

Sumitomo can evaluate many older and installed SEISA gearboxes through its industrial gearbox repair services . The available repair, rebuild, component-manufacturing, or replacement options depend on the unit’s identification, condition, configuration, and application.

How can an older SEISA gearbox be identified?

A clear nameplate photo is the best starting point. Model information, ratio, shaft arrangement, mounting position, equipment drawings, overall photos, service records, and application details can also help identify an older or hard-to-document unit.

What information is needed for a SEISA gearbox repair quote?

Include the gearbox nameplate, model information, application, operating symptoms, photos, and any available service history. Details about noise, vibration, temperature, oil leakage, lubrication condition, loading, and recent performance changes can help the repair team assess the next step.

Can a SEISA gearbox be inspected or serviced on-site?

On-site support may be available depending on the unit, facility, and work required. Sumitomo’s gearbox inspection and maintenance services can help evaluate vibration, temperature, alignment, lubrication, visible condition, and other operating concerns. Complete teardown, machining, gear manufacturing, and controlled testing may require the gearbox to be sent to a repair facility.

Can damaged SEISA gearbox components be manufactured or restored?

Depending on the inspection findings, repair work may include gear manufacturing, shaft restoration, housing work, machining, bearing and seal replacement, or other component repairs. The recommendation depends on the component’s condition, dimensions, material requirements, and role within the gearbox.

When should a SEISA gearbox be rebuilt or replaced?

A rebuild may be appropriate when several internal components require work but the housing and overall configuration can remain in service. Replacement may be more practical when damage is extensive, the housing cannot be restored, required components cannot be supported, operating requirements have changed, or the repair cost and schedule no longer make sense for the application.
