Linear technique
Linear technology is used where the part does not move in rotation, but exactly in a straight line. It is used for automation, fixtures, handling equipment, CNC nodes and minor machining.
When choosing, it is necessary to distinguish between a guide with a carriage, a circular rod with a linear sleeve or another storage system. Each solution has different demands on stiffness, precision, lubrication and mounting space.
Problems often arise when replacing a cart with a different height or with a sleeve that does not match the diameter of the rod. The direction of the load and protection against dust are also important.
- specify line type, stroke length and mounting spacing
- for trolleys, check the width, height and number of fastening holes
- for bushings, measure rod diameter and body length
- take into account lubrication, shielding and required movement accuracy
A dimensional sketch, carriage or housing designation and information on whether it is a precise guide, a light slide or a loaded application will help to design a replacement.
