The IKO TLA48Z is a metric caged shell needle roller bearing designed to provide efficient rotational support in applications with limited radial space. Featuring a 4mm bore diameter, 8mm outside diameter, and 8mm width, this bearing is engineered for high-speed rotation and heavy-load handling. The caged design ensures precise needle roller guidance, enhancing performance and extending service life. Constructed from chromium molybdenum steel, the TLA48Z offers a dynamic load capacity of 1350 N and a static load capacity of 1010 N, accommodating various operational demands. Its open closure type facilitates easy lubrication and maintenance, while the maximum rotational speed of 75,000 rpm (with oil lubrication) and 45,000 rpm (with grease lubrication) supports high-speed applications. This bearing is ideal for use in mass-produced articles requiring economy and is suitable for applications where axial positioning fixtures are not feasible. Its low-profile design allows for streamlined integration into compact machinery, optimizing space utilization without compromising performance.
