💡 How does an inner ring in a thrust roller bearing affect axial load capacity in linear slide units? The inner ring provides the hardened raceway and alignment needed for reliable axial load support. - It gives rollers a precise contact surface, improving load distribution and bearing life. - Proper ID, OD and width sizing ensures fit with AZ and NTB series bearings and sealed ball bearing housings. - Use matched components in linear motion and slide unit assemblies for best performance.
