What are the dimensions of this SKF needle roller bearing?

This needle roller bearing has a 12 mm inner diameter, a 19 mm outer diameter, and a 12 mm width.

Does this bearing include an inner ring?

No, this model comes without an inner ring and runs directly on a hardened and ground shaft raceway.

Is this SKF bearing sealed?

No, this is an open bearing without integrated seals.

What material is the cage made of?

The cage of this single row bearing is made of sheet steel.

Why choose a needle bearing without an inner ring?

It provides a compact design and allows for a larger, stiffer shaft where radial space is limited.

Compact radial performance for tight spaces

Practical benefits

High radial capacity: You support heavy radial loads efficiently in mechanical assemblies where radial cross-sectional space is minimal.
Space-saving shaft integration: Operating without an inner ring, you utilize the hardened shaft raceway directly for maximum compactness.
Rigid Skf construction: The machined outer ring with integral flanges and sheet steel cage provides reliable roller guidance.

In a nutshell

The right choise for

With the single row Skf nk 12/12 needle roller bearing, you achieve high load capacity in extremely confined radial spaces. Because this open bearing is designed without an inner ring, a hardened and ground 12 mm shaft serves directly as the raceway. This saves critical space in gearboxes, transmissions, and hydraulic pumps while allowing for a stiffer shaft design. The solid outer ring with integral flanges and a durable sheet steel cage ensures precise needle roller guidance under heavy radial loads. This setup delivers dependable mechanical performance with a compact 19 mm outer diameter and 12 mm width.

Product description

Single row needle roller bearings without an inner ring consist of an outer ring with a needle roller and cage assembly. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.

High radial load carrying capacity
High stiffness
Low cross-sectional height
Accommodate axial displacement in both directions
