Please note: picture is for reference only. Actual delivered goods shall prevail. What is included 4 linear bearings delivered as a set. Key benefits Smooth linear movement that reduces friction and helps components move more reliably. Improves motion transmission efficiency in systems where rotary motion is converted to linear motion. Simple dropin upgrade for compatible shafts and guides to reduce wear on mating parts. Function and performance Designed to guide and support shafts for linear motion applications. Promotes consistent, lowfriction travel for repeatable positioning and operation. Helps extend the service life of shafts and related components by reducing surface wear. Compatibility and sizing Supplied as four identical linear bearings. Confirm that the bearing inner diameter matches your shaft diameter before installation. Suitable for standard linear shaft systems when dimensions match. Check product listing or equipment drawings for measurements. Material and durability Manufactured to provide consistent running characteristics. For performance use with properly finished and dimensionally accurate shafts. Regular maintenance such as appropriate lubrication will support long term performance. Typical applications 3D printers and CNC machines for guiding axes and improving print or cut consistency. DIY linear slides, camera sliders, or automated fixtures where smooth linear travel is required. Robotic assemblies and positioning systems that require repeatable linear motion. Installation tips Verify bearing inner diameter matches the shaft diameter and that shafts are straight and clean. Apply suitable lubricant compatible with bearing and shaft materials before first use. Ensure correct alignment when mounting to avoid premature wear.
