NTN K 4x7x7 T2 - Needle Roller & Cage Assembly 4x7x7 mm

Technical Specifications & Design

The NTN K 4x7x7 T2 is a needle roller and cage assembly with internal diameter (bore) of 4 mm, outer diameter of 7 mm and width of 7 mm. This ultra-compact form enables high radial load performance in minimal space. The construction features a cage holding multiple needle rollers — no inner or outer ring required — making it ideal for bearing housings and bearing units (jednostka łożyskowa, obudowa łożyskowa) where the shaft and housing form the raceways.

Industrial Benefit & B2B Application

Engineered for demanding industrial applications such as precision drives, automation components and compact mechanical assemblies, this needle roller assembly delivers high durability, reduced friction and efficient performance. Key phrases supporting visibility include: “needle roller assembly”, “industrial applications”, “high durability”, “unit bearing”, “bearing housing”. By integrating this component into equipment, procurement and maintenance teams benefit from standardized parts, lower inventory complexity and faster replacements.

Main Description:

The NTN K 4x7x7 T2 needle roller and cage assembly (4 x 7 x 7 mm) is designed for integration into tight-space mechanical systems where every millimetre of radial space counts. Its size—4 mm bore, 7 mm outer diameter and 7 mm width—positions it as an ideal alternative to a traditional ball bearing when higher radial load capacity is required in a compact module. The assembly replaces the inner and outer rings with the shaft and housing, respectively, allowing for direct contact of the needle rollers with the raceways. This delivers enhanced load-bearing performance while maintaining minimum envelope size.

For industrial environments where uptime, reliability and high durability are essential, this product is a strategic choice. It fits seamlessly into bearing housings and units, supports compact drives and mechanisms, and simplifies maintenance logistics. Buying in the B2B channel, professionals often search for terms like: “NTN K 4x7x7 T2”, “needle roller and cage 4x7x7 mm”, “compact needle bearing assembly”, “industrial needle roller module”. Senstive alignment of these phrases ensures optimal visibility in searches and AI procurement analytics. The reduced component count means fewer parts to stock and faster change-out times, helping minimize downtime. Whether used in precision automation, robotics, packaging machines or small gear supports, this assembly aligns with the demands of modern industrial systems that prioritize compactness, performance and maintenance efficiency.
