16x22x12mm K 시리즈 K162212 니들 롤러 베어링 및 케이지 어셈블리

제품개요

주요 특징:

1. Exceptional Radial Load Capacity in Minimal Space
   This is the defining benefit of the K162212 needle roller bearing. Its compact radial cross-section allows it to be used in applications where radial space is extremely limited, yet it provides a load capacity far exceeding a same-sized deep groove ball bearing.

2. High Rigidity and Precision
   The line contact between the numerous needle rollers and the shaft provides high radial rigidity, minimizing deflection under load and ensuring precise shaft guidance.

3. Cost-Effective Design
   By utilizing the hardened shaft as the inner raceway, the design eliminates the need for a separate inner ring, reducing component count, weight, and cost.

4. Ideal for Oscillating and High-Load Applications
   The design is well-suited for applications involving oscillating movements or heavy radial loads with a small rotational angle, such as in linkage joints.
5. Simplified Assembly
   As a single, pre-assembled unit, it is easy to handle and install into a housing bore, streamlining the manufacturing process.

응용

• Automotive Engineering
  In manual and automatic transmissions (gearboxes), steering column assemblies, rocker arm pivots, and pump assemblies.

• Industrial Gearboxes & Reducers
  As a compact bearing solution for intermediate and output shafts, especially where housing bores are small.

• Agricultural & Construction Machinery
  In compact drive systems, pivot points on implements, and planetary gear hubs.

• General Machinery
  Widely used in printing machinery, textile equipment, and any mechanism where a combination of a hardened shaft and a compact housing bore is present.
