Linear Ball Bearing Units

About

Bearing King supplies a range of high-quality linear ball bearing units designed to provide smooth, accurate and reliable linear movement across a wide variety of industrial and engineering applications. Available in compact, lightweight, heavy-duty, machined and plain bearing configurations, these complete units offer a practical solution where controlled motion, low friction and dependable load support are required. Our range includes INA linear bearings combined with precision-engineered housings to create complete, ready-to-install bearing units. By integrating the linear bearing and housing into a single assembly, these products help simplify machine design and installation while providing consistent performance in demanding operating environments. Whether you are designing production machinery, automation systems, material-handling equipment or precision guidance systems, linear ball bearing units can provide an efficient solution for applications requiring accurate movement along a shaft. What Are Linear Ball Bearing Units? Linear ball bearing units combine a linear bearing with a compatible housing, creating a complete assembly for supporting and guiding movement along a linear shaft. The bearing is positioned securely within the housing and is retained by means of a radial fixing screw, helping to prevent unwanted axial displacement during operation. The linear ball bearing contains rolling elements that circulate as the unit travels along the shaft. This rolling motion helps reduce friction compared with conventional sliding systems, supporting smooth travel, accurate positioning and efficient movement. For applications where rolling elements are not suitable, plain linear bearing units may also be available. These use sliding contact rather than recirculating balls and can be suited to particular operating conditions, loads or environmental requirements.
