Needle roller bearings help you support radial loads when your equipment has limited installation space. 하지만, 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 mm 외경, 그리고 12 mm 너비. 심천 Xinchangsheng 베어링 유한 회사, 주식회사. 이후 정밀 베어링을 제조해왔습니다. 2002. This guide explains the K162212 specifications, operating characteristics, application suitability, and selection factors to help you make an informed purchasing decision.
K162212 니들 롤러 베어링: 주요 사양
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.

Why Choose a Needle Roller Bearing and Cage Assembly?
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:
- Compact construction: The small radial cross-section helps you accommodate bearing support in space-constrained equipment.
- Radial load capacity: Needle rollers provide a relatively large contact area for supporting radial loads.
- Controlled roller spacing: The cage helps guide the rollers and maintain their arrangement during operation.
- Reduced component count: A separate inner ring may be unnecessary when the shaft itself provides a suitable raceway.
- Flexible integration: The assembly can suit equipment designs that require compact bearing arrangements.
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.
Applications of K Series Needle Roller Bearings
The K162212’s compact dimensions make it a candidate for machinery where radial space is limited. You should confirm the actual load, 속도, lubrication, and mounting conditions before specifying it for any application.
Automotive Transmissions and Steering Systems
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.
산업용 기어박스 및 감속기
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.
설치 전, verify the shaft and housing dimensions against the manufacturer’s drawing. 또한, confirm the required load ratings and operating speed rather than relying on dimensions alone.
Agricultural and General Machinery
Printing equipment, 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, 충격 하중, and maintenance intervals. These factors can affect service life even when the bearing dimensions are correct.

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.
How to Select the Right K162212 Bearing
Follow these steps before placing your order:
- Confirm the dimensions. Check the 16 mm shaft diameter, 22 mm 외경, 그리고 12 mm width against your technical drawing.
- Inspect the shaft raceway. Verify hardness, surface finish, roundness, and dimensional tolerances against the applicable bearing specifications.
- Calculate the operating load. Determine the radial load, shock conditions, expected life, and required safety margin. Request the dynamic and static load ratings if they are not listed in the product documentation.
- Check speed and lubrication. Confirm the operating speed, lubricant type, temperature range, and maintenance requirements with your bearing supplier.
- Verify installation conditions. Review housing fit, 조정, available clearance, and assembly procedures.
- Confirm the order details. Request a technical drawing, applicable tolerances, material information, and inspection documentation before approving the bearing for production.
This process helps you compare products based on engineering requirements rather than dimensions alone.
FAQ
1. What are the dimensions of the K162212 needle roller bearing?
The K162212 has a 16 mm bore or shaft diameter (앞으로), 에이 22 mm 외경 (디), 그리고 12 mm 너비 (기음). Confirm these dimensions against the manufacturer’s drawing before installation.
