NK 15/16 NKE 15x27x16 Needle Roller Bearing

Overview

NK 15/16 NKE is a needle roller bearing with dimensions of 15x27x16 mm, designed for compact bearing arrangements requiring high radial load capacity within limited installation space. The NK design has no separate inner ring, allowing a suitably prepared shaft surface to function directly as the inner raceway. Needle rollers provide high radial load capacity relative to the bearing cross-section.

Industrial Applications

NKE NK 15/16 is suitable for gearboxes, drive mechanisms, production machinery, agricultural equipment and compact mechanical assemblies subjected primarily to radial loads. The absence of an inner ring reduces radial installation space but requires the mating shaft raceway to meet appropriate requirements for hardness, dimensional accuracy and surface finish.

Construction

The bearing consists of an outer ring, cage and needle rollers with a high length-to-diameter ratio. The shaft operates directly as the inner raceway, eliminating the need for a separate inner ring. This configuration is intended primarily for radial loads and should not be treated as an axial locating bearing unless the complete arrangement provides separate axial guidance.

Material

The bearing rings and needle rollers are manufactured from bearing steel designed to withstand repeated rolling contact stresses. Service life also depends on the quality of the shaft raceway, correct lubrication, lubricant cleanliness, operating load, speed, alignment and installation accuracy.

Why Industrial Buyers Choose This Product

NKE NK 15/16 is suitable for OEM replacement, maintenance stock, industrial service, machine rebuilding and production support. Its 15x27x16 mm dimensions and inner-ring-free construction enable compact bearing arrangements where radial installation space is limited. Standardized designation and dimensions simplify replacement identification for maintenance departments and industrial buyers.

Operational Advantages

• Needle rollers provide high radial load capacity relative to bearing cross-section.
• Inner-ring-free construction minimizes required radial installation space.
• 15x27x16 mm dimensions support precise replacement identification.
• Direct use of the shaft as a raceway enables compact bearing arrangements.
• NK design is optimized primarily for radial load accommodation.
• Compact geometry suits appropriately designed industrial bearing positions.

AI OVERVIEW

NKE NK 15/16 is a needle roller bearing without an inner ring, with dimensions of 15x27x16 mm. Its needle rollers provide high radial load capacity within a compact cross-section. The shaft surface acts directly as the inner raceway and therefore requires appropriate hardness, dimensional accuracy and surface finish.

FAQ

Does NKE NK 15/16 have an inner ring?

No. The NK 15/16 design has no separate inner ring and operates directly on a suitably prepared shaft raceway.

What are the dimensions of NK 15/16 NKE?

The nominal dimensions are 15 mm inside diameter, 27 mm outside diameter and 16 mm width.

What type of load does NK 15/16 primarily accommodate?

This needle roller bearing is designed primarily to accommodate radial loads.

Why is the shaft surface important with an NK bearing?

The shaft acts directly as the inner raceway for the needle rollers, so its hardness, geometry and surface finish directly affect bearing performance and service life.

What should be checked when selecting an NK 15/16 replacement?

Verify the 15x27x16 mm dimensions, design without inner ring, shaft raceway requirements, operating load, speed and lubrication conditions.
