Exchange Units & Replacement Components
Repair is not always the most practical answer. Production schedules may not allow time for a standard rebuild, the original component may be beyond economical repair, or a replacement may be difficult to locate through traditional channels. NNG Industries helps customers evaluate exchange, replacement and sourcing options for spindles, ballscrews, workholding systems and other critical machine components. The goal is to compare the available paths based on component condition, inventory, core requirements, machine specifications, lead time and production priorities.
Exchange Unit Evaluation
Review of compatible rebuilt or serviceable exchange units when inventory and core requirements allow.
New & Rebuilt Components
Sourcing support for new and rebuilt machine components based on application, availability and approved requirements.
OEM & Aftermarket Sourcing
Support locating OEM or qualified aftermarket components based on fit, function, availability and machine requirements.
Obsolete & Hard-to-Source Parts
Assistance identifying discontinued, legacy and difficult-to-find components when standard supply channels are limited.
Used Component Options
Evaluation of used components when appropriate for the machine, application, condition and production requirements.
Core Returns & Logistics
Coordination support for shipping, pickup, core inspection, return requirements and related exchange logistics.
Identify → Evaluate → Source → Approve → Coordinate → Deliver
More Ways to Keep Production Moving
When a failed component cannot wait for a normal repair cycle, customers need practical alternatives. NNG evaluates the equipment, component details, available inventory and sourcing options so manufacturers can compare repair, exchange and replacement paths before committing to a costly decision.
One component problem. More than one possible path. Support across multiple machine systems through one relationship.
Exchange & Replacement Components We Support
NNG supports machine-tool components used across CNC and industrial equipment. Availability depends on the manufacturer, model, configuration, component condition, technical information, inventory, and sourcing options.
Current & Legacy Equipment
NNG may assist with components used across current, discontinued and obsolete equipment when repairable cores, drawings, replacement options or qualified alternatives remain available.
Service Coordination
Depending on the project, NNG may coordinate intake, shipping, pickup, core inspection, replacement sourcing and return logistics.

The Right Path...
The right path depends on the failed component, machine requirements, available inventory, core condition, lead time and production priorities.
Exchange
Replace the failed unit with a compatible rebuilt or serviceable exchange component when inventory and core requirements allow.
Repair
When an exchange or replacement is not available, NNG may evaluate whether repair or rebuilding is the more practical path.
Replace
Source a new, rebuilt or used component when the original unit is no longer practical to repair.
Source
Locate OEM, aftermarket, obsolete or hard-to-find components based on the machine and application requirements.
EXCHANGE & REPLACEMENT QUESTIONS
What Customers Need to Know
Answers to common questions about evaluation, testing, exchange availability and what to send with a service request.
What information should I provide?
Send the machine manufacturer and model, component manufacturer and model, part number, serial number, photos, symptoms and required timing.
What is an exchange unit?
An exchange unit is a compatible rebuilt or serviceable component supplied in place of the failed unit, usually with a core-return requirement.
Are exchange units always available?
No. Availability depends on the manufacturer, model, configuration, inventory and condition of the returned core.
What is a core return?
A core return is the failed component sent back after the exchange unit is supplied. Inspection requirements, deadlines and credits may apply.
Can NNG source obsolete components?
Support may be possible when the component can be identified through part numbers, drawings, dimensions, machine information or qualified alternatives.
Does NNG supply OEM and aftermarket components?
NNG may assist with OEM and qualified aftermarket sourcing depending on fit, function, availability and customer requirements.
Are used components available?
Used components may be considered when appropriate for the machine, application, condition and production needs.
What happens if an exchange unit is not available?
NNG may help evaluate repair, rebuilding, new replacement, used replacement or alternative sourcing options.
Need an Exchange Unit or Replacement Component?
Send the machine manufacturer, model, component details, serial number, photos and required timing. NNG will review the information and help identify available exchange, replacement or sourcing options.
