- Optical Axis: Provides a fixed path for light transmission in optical systems, supporting precise alignment and repeatable performance. - Open Fixed Bearing: Allows smooth rotation when needed and can be locked in a fixed position, reducing setup time and eliminating unwanted movement. - Stop Shaft Clamp: Securely clamps the shaft to prevent axial or lateral movement, preserving tolerance and stability during operation. - SCS Limit Ring with Screw: Screw-adjustable limit ring that controls the movement range, enabling easy recoil-free reconfiguration for different tasks. - Scsaw Type (12 30 10): Specifies a particular type defined by the 12 30 10 specification, ensuring standardized compatibility within the system. Use scenarios - Optical bench or laser alignment: Use the fixed optical axis to maintain beam position while using the adjustable limit ring to set safe travel, then lock the bearing when measurements are complete. - Rotating stage or precision instrument assembly: Employ the open fixed bearing for position changes and use the shaft clamp to secure the shaft after alignment to maintain reproducible results. - Machinery or test rig with defined motion limits: Apply the screw-adjustable limit ring to set travel boundaries and clamp the shaft to prevent drift during long-duration tests.
