Needle roller bearings help you support radial loads when your equipment has limited installation space. Однако, choosing the wrong bearing dimensions or overlooking shaft and housing requirements can lead to poor fit, excessive wear, and unexpected maintenance. If you are sourcing a compact bearing for a transmission, industrial gearbox, or mechanical linkage, you need to evaluate more than the product name.
The K162212 K Series needle roller bearing and cage assembly from XCCZC offers a compact design with a 16 mm shaft diameter, 22 мм внешний диаметр, и 12 ширина мм. Шэньчжэньская подшипниковая компания Xinchangsheng., ООО. производит прецизионные подшипники с тех пор 2002. This guide explains the K162212 specifications, operating characteristics, application suitability, and selection factors to help you make an informed purchasing decision.
The K162212 is a needle roller bearing and cage assembly designed to accommodate radial loads within a small radial cross-section. Its cylindrical needle rollers distribute loads along their contact lines, making this bearing type useful in compact mechanical assemblies.
Перед заказом, check the following dimensions and confirm that they match your equipment drawings.
| Спецификация | K162212 details |
|---|---|
| Bearing series | K Series |
| Тип подшипника | Needle roller bearing and cage assembly |
| Диаметр отверстия (Фу) | 16 мм |
| Внешний диаметр (Д) | 22 мм |
| Ширина (С) | 12 мм |
| Radial load support | Designed for radial loads |
| Inner raceway | Requires a suitable shaft raceway |
| Typical applications | Трансмиссии, коробки передач, системы рулевого управления, compact machinery |
The listed dimensions provide a starting point for selection. Однако, you should also verify the shaft hardness, raceway accuracy, lubrication method, рабочая скорость, and available installation clearance.
A needle roller bearing and cage assembly uses a cage to maintain spacing between the needle rollers. Depending on the design, the assembly can operate directly against a properly prepared shaft raceway without a separate inner ring.
Key characteristics include:
Keep in mind that the shaft must meet the bearing’s raceway requirements. A standard shaft surface may not provide the hardness, finish, or dimensional accuracy needed for reliable operation.
The K162212’s compact dimensions make it a candidate for machinery where radial space is limited. You should confirm the actual load, скорость, смазка, and mounting conditions before specifying it for any application.
Transmission mechanisms often contain closely spaced shafts and gears. Needle roller bearing assemblies can support radial loads while helping designers keep the bearing arrangement compact.
For steering components and mechanical linkages, evaluate the direction of loading and whether the movement involves continuous rotation or oscillation.
Compact gearboxes may require bearing arrangements that fit within restricted housing dimensions. The K162212’s 16 × 22 × 12 mm dimensions can help you assess whether it fits your available space.
Before installation, verify the shaft and housing dimensions against the manufacturer’s drawing. Также, confirm the required load ratings and operating speed rather than relying on dimensions alone.
Печатное оборудование, textile machinery, agricultural drives, and other mechanical systems may use needle roller bearings in compact rotating or pivoting assemblies.
For these applications, consider dust exposure, lubrication access, ударные нагрузки, and maintenance intervals. These factors can affect service life even when the bearing dimensions are correct.
Both bearing types support radial loads, but their structures and installation requirements differ.
| Comparison factor | Needle roller bearing | Радиальный шарикоподшипник |
|---|---|---|
| Rolling element | Cylindrical needle rollers | Spherical balls |
| Radial space | Generally compact for its load capacity | Depends on bearing series and size |
| Primary load support | Радиальные нагрузки | Radial loads and some axial loads |
| Shaft requirements | Some designs require a hardened shaft raceway | Commonly uses an inner ring |
| Typical design priority | High radial load capacity in limited space | Versatile radial support and rotational operation |
| Selection considerations | Качество гоночной трассы, смазка, выравнивание, нагрузка | Распродажа, скорость, осевая нагрузка, смазка |
Neither type is universally better. If your design prioritizes radial load capacity within a restricted cross-section, a needle roller bearing may be appropriate. If your equipment also needs axial load support, evaluate whether a deep groove ball bearing or another bearing arrangement better meets your requirements.

Follow these steps before placing your order:
This process helps you compare products based on engineering requirements rather than dimensions alone.
The K162212 has a 16 mm bore or shaft diameter (Фу), а 22 мм внешний диаметр (Д), и 12 ширина мм (С). Confirm these dimensions against the manufacturer’s drawing before installation.
The K Series needle roller bearing and cage assembly can use a suitable shaft as its inner raceway. The shaft must meet the required hardness, surface finish, and dimensional tolerances. Confirm the specific installation requirements before using a shaft without an inner ring.
Contact XCCZC to request the applicable dynamic and static load ratings, dimensional tolerances, material details, and operating recommendations. These specifications help you determine whether the bearing meets your equipment’s requirements.
Needle roller bearings provide a practical option for compact mechanical assemblies that require radial load support. The K162212 model combines a 16 mm shaft diameter, 22 мм внешний диаметр, и 12 mm width in a needle roller bearing and cage assembly. Before choosing this model, verify the load ratings, shaft raceway conditions, lubrication requirements, and operating environment to ensure compatibility with your application.
