Adjustable telescoping component with a compact closed profile and a longer extended reach. Key specifications are provided to ensure accurate selection for mounting and alignment tasks. Dimensions Closed height (A): 105 mm Extended height (B): 155 mm Outside diameter (D): 87 mm Inside diameter (E): 70 mm Key benefits Adjustable length from 105 mm to 155 mm to fit changing space and reach requirements. Defined external envelope of 87 mm supports placement in confined or crowded assemblies. Internal bore of 70 mm provides a clear through or mounting passage for components that require a 70 mm diameter clearance. Consistent overall sizing simplifies integration into existing brackets, frames, or housings. Compatibility and fit Outer diameter 87 mm ensures compatibility with mounting spaces designed for this envelope. Inner bore 70 mm accommodates parts or assemblies that require up to 70 mm clearance. Use scenarios Automotive or industrial equipment: serves as an adjustable spacer or mounting sleeve in tight engine compartments or control panels where space is limited but reach is required. Manufacturing fixtures or jigs: provides adjustable length to set precise offsets during assembly or testing processes. Instrumentation mounts: offers flexible positioning in labs or field setups where components need to be aligned at different heights while preserving a compact footprint.
