NKE NKIA 5909 Combined Needle-Roller Bearing 45x68x30

Technical Data & Key Features

The NKE NKIA 5909 is a compact, combined needle-roller/angular-contact bearing unit with inner diameter 45 mm, outer diameter 68 mm and width 30 mm. Designed as a high-capacity bearing unit for industrial applications, it integrates a radial needle-roller bearing section and an angular-contact ball bearing section to handle both radial loads and axial loads in one direction.
Key features include:

• High load-carrying capacity: Designed to sustain significant radial loads combined with directional axial loads, making it ideal for demanding machine assemblies.

• Compact cross-section: The low height of only 30 mm supports design of machines with constrained space, while enabling integration into a bearing housing unit or obudowa łożyskowa.

• Versatile industrial readiness: Suited for automation, drive units, conveyor equipment, and machines requiring both radial and axial support under high durability conditions.

• Standardised dimensions and interchangeability: 45x68x30 mm is a widely searched size in English-language markets: “combined needle-roller bearing 45x68x30”, “NKIA 5909 bearing”, “needle roller angular contact ball bearing 45 x 68 x 30”.
  By incorporating the unit into your parts stocking strategy, you benefit from a ready-to-mount unit that reduces downtime and integrates smoothly into assembled bearing units, enabling maintenance and production continuity in B2B environments.

Applications & Industrial Benefits

For B2B operations in heavy-duty machinery, the NKE NKIA 5909 bearing provides an ideal solution where a compact unit must perform under mixed loading—radial plus axial—and where the requirement for high durability is pressing. The bearing unit is especially suited for integration as a “unit łożyskowa” within a housing, or as a component in obudowa łożyskowa for drives, gearboxes, industrial conveyors, machine tools and automation systems.
By choosing this bearing, you secure:

• A durable component that supports high reliability and minimizes maintenance costs.

• Flexibility in design: the combined needle-roller + angular contact ball bearing structure suits applications with axial thrust in one direction and radial loads.

• Space efficiency: the 45x68x30 mm dimension simplifies retrofits and supports OEM applications with constrained envelope.

• B2B operation readiness: clear specification, industry-recognized size, suitable for procurement and maintenance departments in global B2B marketplaces looking for “industrial bearing 45x68x30 mm”, “needle roller combined bearing NKIA5909”, or “NKE NKIA5909 bearing unit”.

FAQ

Q1: What type of loads can the NKE NKIA 5909 handle?
A1: It is engineered as a combined bearing unit to handle radial loads plus axial loads in one direction, thanks to the integrated needle-roller section and angular-contact ball bearing section.
Q2: Why is the compact width of 30 mm significant?
A2: The narrow cross-section enables this bearing to be used in machine designs where space is limited while still offering high load capacity—ideal for retrofit or OEM applications.
Q3: Is this bearing ready for integration into a bearing housing unit?
A3: Yes. The dimensioned specification 45x68x30 mm and its combined construction make it suitable as a unit łożyskowa or in a housing (obudowa łożyskowa) with minimal adaptation.
Q4: What key search phrases do engineers use for this product?
A4: Some common English-language search phrases include: “combined needle roller bearing 45x68x30”, “NKE NKIA5909 bearing”, “needle roller angular contact ball bearing 45 x 68 x 30 mm”, “industrial bearing 45x68x30”. These align with procurement-oriented search intent.
Q5: How does selecting this bearing benefit maintenance and procurement teams?
A5: It offers high durability and reliability, compact size for easier integration, and a defined dimension and type which simplifies sourcing, stocking and replacement in industrial operations.
