- Automated test equipment positioning stages
- Semiconductor wafer handling arms
- Food processing conveyor gate actuators
Installation note:
Maintain 0.05mm minimum clearance between rod end and load during alignment.
For vertical mounting, use locking nut (AJS-M6 sold separately) to prevent unscrewing.
Critical parameter:
Maximum side load capacity 15N. Exceeding this limit requires
external guide mechanism (recommend AGB12 guide kit).
