A ball spline is a type of rolling bearing linear guide, similar to a round shaft and bushing assembly, but with a critical distinction in its operation. The shaft of a ball spline is much like a linear guide shaft, except that the spline shaft has grooves along its length. The spline nut (analogous to […]

Common applications for linear rails
Linear rails are the backbone of many industrial applications, providing low-friction guidance and high stiffness for loads that can range from just a few grams to thousands of kilograms. Their range of sizes, accuracy classes, and preloads make linear rails suitable for virtually any performance requirement. The reasons for using linear rails are numerous, but […]
Linear motion for robotic handling in automated warehouses
When designing and configuring an automated warehouse, one design goal is to keep the system as light and compact as possible. Depending on the size of the load being moved, there are two common types of automated warehouses. In lighter applications, aluminum structures can handle loads up to 100 kilograms, while steel structures are good […]
IKO MX series of linear roller bearings — now more standard variations
IKO Intl. now offers more variations in its standard MX series of linear roller bearings to include special features for environments that are sensitive to metal chips, dust, and other contaminants. High load capacity. The MX models utilize rows of cylindrical rollers to provide a greater contact area than slides that use steel balls. They […]
