The 0045-90049 LEADSCREW, INDEXER, 300LG C/W NUT is a precision-engineered motion transmission component used in Applied Materials semiconductor equipment to support controlled indexing movement, positional accuracy, and reliable wafer handling subsystem performance.
Installed within indexer or robotic motion assemblies, this leadscrew and nut assembly converts rotational motion into controlled linear movement, supporting repeatable positioning and coordinated subsystem motion critical to semiconductor transfer operations. In applications where tight tolerances, repeatable travel, and stable motion control drive transfer reliability and yield protection, dependable leadscrew performance is critical.
Because leadscrew assemblies operate under sustained mechanical cycling, precision load transfer, contamination-sensitive conditions, and demanding uptime requirements, wear, backlash development, thread degradation, lubrication breakdown, or alignment drift can contribute to positioning errors, transfer instability, motion faults, or unplanned downtime. The 0045-90049 is engineered to support stable motion transmission performance under demanding fab operating conditions.
The 0045-90049 functions as a critical motion transmission and indexing component.
Core functions include:
The leadscrew assembly supports repeatable controlled movement.
Key performance characteristics include:
Transfer stability and repeatable operation rest on reliable motion accuracy.
Mechanical transmission integrity is central to performance.
Performance attributes may include:
Stable drive mechanics help preserve subsystem accuracy.
Designed for demanding semiconductor production environments.
Durability characteristics may include:
Reliable component condition helps support throughput and uptime.
The 0045-90049 may operate alongside related components including:
Together these components support broader motion precision and equipment reliability.
The 0045-90049 can directly influence transfer accuracy and equipment availability.
Potential impacts of wear or degradation include:
Replacing a worn leadscrew assembly can restore motion precision and improve subsystem reliability.
Repeated mechanical duty may gradually affect motion performance.
Indicators include:
Mechanical interfaces may degrade over time.
Symptoms may include:
Long-term duty may affect fit and motion quality.
Indicators include:
Wear in the 0045-90049 may also increase stress on associated hardware such as 0010-76800 or 0010-70264, particularly in tightly integrated motion architectures.
To support best performance:
The 0045-90049 Leadscrew, Indexer, 300LG C/W Nut is an Applied Materials OEM part.
Key considerations:
Maintaining strategic inventory of the 0045-90049 and related components such as 0010-76800, 0010-70264, and 0020-84222 can reduce downtime exposure and improve maintenance readiness.
It converts rotational input into controlled linear indexing motion, supporting precise positioning and repeatable subsystem movement.
Because leadscrews support controlled motion accuracy required for reliable transfer, positioning precision, and subsystem coordination.
It generally indicates a 300-length leadscrew supplied complete with matching nut assembly, though exact specifications should be verified against OEM documentation.
Common indicators include:
Yes. Wear or backlash can contribute to positioning errors, motion instability, or transfer faults.
Yes. Mechanical wear often progresses gradually and may affect repeatability before a major failure event.
Yes. Motion subsystem issues can lead to increased faults, maintenance interventions, or unplanned downtime.
Problems may be identified through motion diagnostics, backlash measurement, PM inspection, positioning drift analysis, or recurring subsystem faults.
Yes. Motion verification and subsystem checks should be performed after replacement before returning the tool to production.
Yes. Degraded leadscrew performance can increase stress on associated indexers, motors, or transfer hardware.
Incorrect hardware may cause compatibility issues, travel errors, alignment problems, or subsystem faults.
Yes. Mechanical, dimensional, and subsystem compatibility should be confirmed against OEM requirements.
Yes. ESCT supports functional and compatibility verification aligned with OEM requirements.
Depending on availability, associated robotic, motion, and wafer handling hardware may also be supported.
