HK 2216 LL/3AS NTN 22x28x16 - needle roller bearing

Applications

The HK 2216 LL/3AS NTN 22x28x16 is a needle roller bearing designed for high radial loads where installation space is limited. It is widely used in industrial applications such as gearboxes, transmissions, agricultural machinery, conveying systems and drive mechanisms. The bearing is supplied without an inner ring, allowing direct cooperation with a hardened shaft and compact system design.

Advantages

The HK design offers a very high load capacity relative to its size. The LL/3AS version features double sealing, protecting rolling elements from contamination and retaining lubricant inside the bearing. This significantly increases high durability and operational reliability. Precision manufacturing by NTN ensures stable operation, low friction and long service life, even under continuous duty. Compared with solutions like a ball bearing, needle roller bearings allow higher radial loads at the same shaft diameter.

Main description

The HK 2216 LL/3AS NTN 22x28x16 is a precision needle roller bearing developed for compact assemblies requiring high radial load capacity. The absence of an inner ring allows the bearing to run directly on a properly hardened and ground shaft, reducing overall dimensions and system weight.

Double seals effectively protect the bearing interior against dust and contaminants, which is essential in industrial environments. At the same time, the seals retain grease inside the bearing, extending service intervals and ensuring consistent performance. Compared to a ball bearing, the needle roller design provides a much higher radial load capacity in a smaller cross section.

With standard 22x28x16 dimensions, the bearing can be easily integrated into existing designs and used together with a bearing housing or as part of a complete bearing unit. It is a reliable choice for B2B customers looking for durability, precision and immediate availability for demanding industrial machinery.

FAQ
