IKO BA 98 Z O H Caged Metric Needle Roller Bearing | High Radial Load Capacity

The IKO BA 98 Z O H is a high-performance, metric caged needle roller bearing designed for applications where radial space is severely limited but high load handling is critical. Constructed with precision-machined steel components and featuring a robust cage assembly, this bearing ensures optimal alignment and retention of the rollers, leading to reduced friction and superior operating efficiency. Its structure—without an inner ring—allows the bearing to utilize the hardened and ground shaft surface as the raceway, maximizing roller diameter and dynamic load capacity relative to its envelope dimensions. Engineered for precision and longevity, the BA 98 Z O H guarantees reliable performance under demanding industrial conditions. Ideal for use in hydraulic pumps, power tool gearboxes, automotive transmissions, and heavy industrial machinery, the BA 98 Z O H offers significant advantages in both efficiency and maintenance. The design promotes smooth operation at higher rotational speeds compared to full complement bearings, extending lubrication intervals and overall service life. Choosing this IKO specialized bearing ensures you are installing a component engineered to withstand high static and dynamic radial loads while maintaining dimensional stability and excellent wear characteristics, making it a cost-effective solution for compact, high-stress mechanisms.
