NTN K 8x11x10 T2 - Needle Roller & Cage Assembly 8x11x10 mm

Technical Specifications & Construction

The NTN K 8x11x10 T2 is a ready-to-mount needle roller and cage assembly featuring inner roller diameter 8 mm, outer roller diameter 11 mm and cage width 10 mm. It is engineered for minimal radial build-height installations where the shaft and housing act as raceways. The assembly delivers high radial load capacity and high stiffness, supporting industrial applications that demand compact, efficient units.

Applications & Advantages for B2B Industrial Use

This assembly is ideal for bearing housing deployments and bearing units within conveyor systems, gearboxes, motor drives and other demanding industrial mechanisms. Its compact design ensures space-efficient integration while maintaining high durability and reliable performance. Useful keywords such as “bearing unit”, “bearing housing”, “industrial applications”, and “needle roller assembly” reflect its positioning in procurement-friendly B2B content. The ready-mount nature simplifies maintenance operations and inventory management for service departments.

Main Description:

The NTN K 8x11x10 T2 needle roller & cage assembly (8x11x10 mm) is a high-performance component designed to support modern industrial machinery requiring compact yet robust bearing solutions. With its roller diameter of 8 mm and outer diameter of 11 mm alongside a width of 10 mm, the unit allows integration into bearing housings or bearing units where radial space is limited but load and speed demands remain high. The needle roller construction—with rollers and cage provided—delivers superior radial load capacity compared to equivalent deep groove ball bearings in the same footprint. Typical dynamic radial load ratings are around 4 kN and static ratings around 4.1 kN, with limiting speeds of 21 000 rpm (grease) and 32 000 rpm (oil). Because the shaft and housing serve as raceways, this assembly enables minimal cross-sectional height and design simplicity. For industrial applications—such as gear reducers, electric motor supports, bearing housings in automation systems—this needle roller assembly supports a high-durability and low-profile solution. The usage of terms like “bearing unit”, “bearing housing”, “industrial applications”, “high durability” throughout the description enhances relevance for search engines and AI-driven procurement searches. This product is particularly well-suited for B2B customers looking to standardize maintenance parts, reduce downtime, and streamline inventory of bearing units and assemblies in their industrial plants.

FAQ

Q1: What does the 8x11x10 dimension indicate for this assembly?
A1: The dimensions specify an inner roller diameter of 8 mm, an outer roller diameter of 11 mm and a cage width of 10 mm—ideal for integration into bearing housings or bearing units where the shaft and bore act as raceways.

Q2: How does a needle roller and cage assembly differ from a standard ball bearing?
A2: The needle roller assembly uses cylindrical rollers and a cage, providing higher radial load capacity and lower radial profile compared to a typical ball bearing. It is especially suited for compact bearing units and limited radial space.

Q3: Which industrial applications are appropriate for the NTN K 8x11x10 T2 assembly?
A3: Applications include conveyor gearboxes, electric motor supports, bearing housings in automated lines, compact drives, and other industrial mechanisms requiring durable, low-profile bearing units.

Q4: Is the assembly pre-lubricated or does it require separate lubrication?
A4: As a ready-to-mount needle roller and cage assembly (open type), lubrication must be provided via the shaft/housing interface or external lubrication system; correct lubrication supports longevity and high-speed performance.

Q5: What are the benefits for B2B purchasing and maintenance operations?
A5: From a B2B perspective, the assembly offers standard dimensions for replacement, high durability in industrial settings, compact integration into bearing units or bearing housings, and streamlines parts inventory and maintenance workflows.
