NK Series- Needle Rollers
NK Series needle roller bearings are designed for high radial load capacity, excellent rigidity, and compact installation in demanding industrial applications. With a machined outer ring and precision‑guided needle rollers, NK bearings offer superior strength and durability compared to drawn‑cup types, making them ideal for heavy‑duty environments.
These bearings are commonly used in gearboxes, transmissions, pumps, compressors, agricultural machinery, construction equipment and general industrial systems. Their robust construction supports high speeds and provides long service life, even under shock loading or continuous operation.
NK Series bearings are manufactured to ISO standards and deliver low friction, smooth running and consistent performance across a wide temperature and load range. They are often paired with hardened inner rings (IR Series) when the shaft surface is unsuitable for direct roller contact.
Transpower Drives supplies the full NK Series range with fast UK delivery and same‑day collection from our Wellingborough, Northamptonshire facility. We support OEMs, maintenance engineers and machine builders across the East Midlands and nationwide, offering reliable NTN‑SNR stock and technical guidance for all needle‑roller applications.
