ISK Bearings' HK2025 is a drawn cup needle roller bearing (HK series), built from a thin-walled drawn outer ring, a cage, and a full set of needle rollers. Its bore (Fw) is 20mm, outside diameter (D) 26mm, and width (C) 25mm. The very low cross-section lets it retain meaningful load capacity within the same radial envelope. Because the outer ring is a thin-walled drawn shell, it suits drive positions where radial space is limited but a certain needle-roller load capacity is still required. Whether it fits your actual position still depends on speed, load, and the mounting environment being reviewed together.
In the HK series, the outer ring is retained in the housing bore by an interference fit, which usually removes the need for a separate axial locating device. That means your housing bore size and tolerance directly shape how the bearing performs once installed. Since the drawn outer ring is a thin-walled structure, bore accuracy and the shaft surface condition are both worth confirming during selection. If you are evaluating this size, it helps to start from the housing bore diameter, shaft tolerance, and mounting method; if you already have a drawing or a current part number, feel free to share it and we can help match it.
The HK series offers a relatively large grease reservoir, and under suitable conditions it can run for extended periods without frequent re-greasing. That said, the re-greasing interval is affected by speed, temperature, and environment (dust, humidity, and so on), so there is no single answer that holds across every piece of equipment. If you can share speed, load, temperature, and lubrication conditions, we can help assess the likely maintenance rhythm for this size in your position — rather than discovering a gap only after installation.
ISK Bearings was founded in 1991. Our bearings run in equipment across 50 countries and multiple manufacturing sectors, and we are certified to IATF 16949, RoHS, REACH, and SGS. More than simply supplying parts, we prefer to clarify the conditions against your real application before the specification is finalized. If you are evaluating the HK2025 or an alternative source, share the bore, housing fit, and a rough picture of the operating conditions; if you already have a part number, drawing, or sample, include it and we'll help assess the next step.
Some non-standard or currently out-of-stock bearings may not be immediately available. If you have specific requirements, feel free to contact us — we will do our best to confirm lead times and provide alternative solutions.
