Secure clamping mechanism The split fixed ring uses a strength bolt clamping system to grip the shaft securely without causing damage. This provides reliable positioning and reduces shaft wear across applications. Package Includes Each includes two clamping shaft collars, offering immediate value for multipoint mounting or spare parts. Easy Installation The Optical Axis Shaft Collars are designed for straightforward installation and removal, enabling quick adjustments or disassembly in setups that require frequent changes. Material and Durability Made from aluminum alloy, these collars are lightweight yet sturdy. The surface is oxidized to enhance resistance to corrosion and wear, contributing to longterm durability. Applications Secure components on optical benches and alignments along the optical axis. Hold shafts in CNC machines, robotics, or other motion systems where precise position must be maintained but adjustments are common. Mount sensors or optics in lab experiments or educational setups requiring frequent reconfiguration along the axis.
