💡 How do I choose an inner ring for a thrust roller bearing in a linear slide unit? Choosing the right inner ring helps bearings handle axial loads and fit the mating rollers correctly. Short intro: pick by dimensions, fit, and application. - Verify I.D., O.D., and width match the shaft and bearing assembly for accurate preload and alignment - Check series compatibility (WS metric, AZ, AZK, NTB) and whether you need sealed ball bearing or ceramic options for contamination or speed - Consider operating conditions like axial load, speed, and exposure to contaminants for material and sealing choices
