NTN NKX 40 40x52x32 mm - Combined Needle Roller and Thrust Ball Bearing

Technical Specifications & Construction

The NTN NKX 40 bearing features dimensions of 40 mm bore (inner diameter), 52 mm outer diameter and 32 mm width. This compact size makes it ideal for industrial applications where space is constrained and performance is critical. Designed as a combined bearing unit, it integrates a needle roller section for radial load support and a thrust ball bearing segment to handle axial thrust loads — providing a dual-purpose solution in one package. The design yields a high radial load capacity relative to its size, and also resists axial displacement, making it a dependable component for bearing housings and modular bearing units. With precision manufacturing and quality materials, this bearing supports continuous operation and contributes to maintenance-efficient systems.

Industrial Applications & Value for B2B

This bearing is specifically tailored for industrial machinery, gearboxes, conveyor systems, motor drives and other demanding installations where reliability, durability and rapid maintenance replacement are key. Phrases like “industrial applications”, “bearing housing”, “bearing unit”, “high durability”, and “ball bearing” appear naturally in this context to enhance search relevance. Procuring this combined type bearing simplifies inventory, as maintenance teams do not need separate radial and thrust bearings. The single unit reduces assembly time and the risk of mismatched components, contributing to lower operational downtime and streamlined B2B procurement.

Main Description:

The NTN NKX 40 40x52x32 mm combined needle roller and thrust ball bearing is engineered for industrial environments requiring both radial and axial load capacity in a compact footprint. With its bore of 40 mm, outer diameter of 52 mm and width of 32 mm, it fits standard bearing housing configurations or modular bearing units without extensive redesign. The needle roller section ensures excellent radial load support and minimal radial space usage, while the integrated thrust ball bearing manages axial forces, creating a versatile dual-load bearing solution. This bearing supports applications such as mechanical drives, gearboxes, motor support shafts and conveyor drive systems — essentially any installation where both radial and thrust loads occur and high durability is required.

For procurement and maintenance managers in B2B environments, the NTN NKX 40 simplifies stock management and reduces part counts: one component replaces separate radial and thrust bearings or complex assemblies. The high-quality design ensures minimal vibration, stable shaft alignment and long service intervals — translating into lower maintenance costs. Recognized search intentions such as “NKX 40 bearing”, “40x52x32 combined bearing”, “needle roller thrust ball bearing 40 x 52 x 32”, and “industrial bearing unit NKX 40” are addressed in this description to support visibility in search engines and AI-based sourcing tools. Built for industrial applications, this product is ideal for usage in bearing housings, modular bearing units and other support structures requiring reliable performance.

Accompanied by high durability and compatibility with standard mounting footprints, this bearing delivers the kind of rugged engineering demanded by production lines, heavy-duty machines and automation systems. Whether your requirement is to replace a worn bearing rapidly or design a new system with minimal radial envelope, the NTN NKX 40 offers a streamlined, effective solution ideal for B2B procurement.
