HK 1214 NKE 12x18x14 needle roller bearing

Main description

The HK 1214 NKE needle roller bearing with dimensions 12x18x14 mm is a compact rolling bearing designed for applications requiring high radial load capacity within very limited installation space.

This model belongs to the HK series of drawn cup needle roller bearings, widely used in mechanical systems where space saving and efficiency are essential. Its design without an inner ring allows direct use of the shaft as a raceway, significantly reducing the overall size of the assembly while maintaining excellent load performance.

The HK 1214 is a common choice in compact industrial and mechanical applications where standard ball bearings cannot meet dimensional constraints.

Construction and design

The HK 1214 NKE is a single row drawn cup needle roller bearing with a thin walled outer ring and a precision cage guiding the needle rollers.

The absence of an inner ring means the shaft must be hardened and ground to function as a raceway. The needle rollers provide line contact, resulting in higher radial load capacity compared to ball bearings of similar size.

The cage ensures proper roller spacing and smooth operation, even under dynamic load conditions and higher speeds.

Industrial applications

This needle roller bearing is widely used in applications where compact size and high load capacity are required.

Typical applications include:
gear systems and mechanical drives
industrial machinery and production equipment
precision tools and mechanical devices
automation systems and robotics
light and medium duty industrial equipment

Within the needle bearing category, the HK 1214 NKE is a versatile and efficient solution for space limited designs.
