Perpendicular Shaft Supports are commonly used in CNC and robotics; these are designed to securely hold a precision linear rail / metal rod in place as a part of a motion platform or other mechanical device. The rod is held tightly in place within the support using a large set screw while the the support has two M6 compatible mounting holes. The support is designed to hold a shaft perpendicular to the mounting surface, with the large mounting holes and set screw easily accessible even when the shaft is installed.
