The IKO HK354518 is a precision open-end drawn cup needle roller bearing designed for high radial load capacity in extremely limited installation spaces. Built in full compliance with ISO 3030 and JIS B 1516 standards, this model features a thin-walled stamped outer ring and full complement needle rollers, delivering exceptional rigidity, low friction, and stable high-speed performance. As a premium IKO needle roller bearing, it is widely recognized in automotive systems, small gearboxes, power tools, and textile machinery for its space-saving structure and reliable heavy-load operation.
The HK354518 bearing has an inner diameter of 35 mm, outer diameter of 45 mm, and width of 18 mm, with a minimum chamfer value rmin of 0.6 mm. It conforms to P0 tolerance class (ISO 492) for general industrial precision. Basic dynamic load rating is 29.2 kN, basic static load rating is 45.5 kN, with a limiting speed of 13,500 r/min under grease lubrication. Its compact radial section makes it ideal for space‑constrained mechanical designs.
The outer drawn cup is made of high-quality cold-rolled carbon steel, heat-treated to 58–62 HRC for high wear resistance. Needle rollers are manufactured from GCr15 / AISI 52100 high-carbon chromium bearing steel, reaching 61–65 HRC with excellent fatigue resistance and dimensional stability. This bearing adopts a full-complement design without a cage, maximizing load-carrying density for heavy radial load applications.
Key processes include precision deep drawing, controlled atmosphere heat treatment, high-precision grinding, and superfinishing. Stamping ensures uniform wall thickness; heat treatment eliminates decarburization and deformation; raceway superfinishing achieves Ra ≤ 0.05 μm to reduce friction and wear. Strict roller sorting ensures consistent size and even load distribution.
Under standard working conditions, the L10 basic rated life reaches 24,000 operating hours, calculated per ISO 281:2007. Service life is mainly affected by lubrication quality, contamination, alignment accuracy, and operating temperature.
The IKO HK354518 is widely used in automotive transmissions, engine accessories, small industrial gearboxes, power tools, textile machines, and office equipment. Its high load capacity and ultra-thin radial design make it the preferred needle roller bearing for compact transmission mechanisms.
Relubricate every 800–1200 operating hours using NLGI 2 lithium-based grease, filling 15–25% of internal space. Clean with kerosene and avoid corrosive agents. Regularly check vibration, noise, and operating temperature; replace the bearing in case of lubricant deterioration or surface wear.
Ensure the housing bore is clean and deburred with H7 tolerance. Use a press to mount the outer cup evenly without hammering. Axial alignment tolerance shall not exceed 0.02 mm. After installation, rotate manually to verify smooth operation; normal operating temperature ≤ 70°C. Wear protective gear during installation to avoid component damage.
