This is a single Extended Round Flange Linear Bearing from the LMF series. The bearing is offered in multiple bore sizes to suit different shaft diameters, including 6, 8, 10, 12, 13, 16, 20, 25, 30, 35, 40, 50 and 60 mm. The listing also notes an example for the LMF25LUU variant with dimensions 25x40x112 (bore 25 mm, outer diameter 40 mm, length 112 mm). The extended round flange provides mounting stability and alignment with a straightforward installation. Key benefits Enables smooth, linear motion on a round shaft with stable mounting. Extended flange design gives secure attachment and alignment, reducing mis alignment during operation. Wide bore size range supports various shaft diameters and mounting configurations. Commonly used with standard round shafts and compatible with standard linear guide setups. Key attributes Functionality: extended round flange linear bearing for linear guidance on a round shaft. Compatibility: designed for the LMF bearing family; suitable for use with standard round shafts and associated mounting hardware. Size: bore sizes available from 6 to 60 mm; example LMF25LUU variant is 25x40x112 (bore 25, outer diameter 40, length 112). Material: material details are not specified in the listing. Performance: intended for precise, smooth motion in compact linear guide applications; suitable for light to mediumload positioning tasks. Use cases CNC or CNClike systems where a stable axis guide is needed for precise positioning. 3D printer assemblies for the X, Y, or Z axis requiring reliable straightline motion with simple mounting. Automated packaging, sorting, or assembly lines where compact linear guidance is required on a moving carriage or subsystem. What's included 1 piece (single extended round flange linear bearing). Installation and compatibility notes Verify bore size to match the shaft diameter and confirm mounting hole pattern on the flange matches your hardware. Check that the flange provides adequate clearance for your mounting surface. If lubrication is required for your application, follow the manufacturer's recommendations for the LMF bearing family.
