High Load K Series Needle Cage and Retainer Assembly K20X26X12 Needle Roller Bearings

K Series Needle Roller and Cage Assembly – The Standard-Setting Compact Radial Bearing Solution

With the lowest cross-sectional height of any rolling bearing and exceptional radial load capacity, K Series assemblies are the first choice for applications where radial installation space is critically limited yet high performance cannot be compromised.

Key Features:

1. High Radial Load Capacity
   K Series assemblies are engineered with a large number of needle rollers, creating extensive line contact between the rollers and raceways.This design distributes loads uniformly across the full complement of rollers. The result is high radial load capacity in an extremely compact bearing envelope.

2. Low Friction, High Speed
   The precision-engineered steel cage spaces the needle rollers evenly, preventing roller-to-roller contact, reducing friction, and ensuring quiet running. The technical enhancements of modern K Series bearings offer improved load distribution, quieter operation, reduced friction, and greater energy efficiency.

3. High Rigidity
   Because the needle rollers make continuous line contact with the raceways, K Series bearings provide excellent stiffness. This high rigidity is critical for applications requiring precise shaft positioning and minimal deflection under load.

4. Cost-Effective
   When shafts and housing bores can be properly hardened and ground to act as raceways, K Series assemblies eliminate the need for separate inner and outer bearing rings — reducing material costs, component weight, and inventory complexity.
5. Multiple Configurations for Any Application
   K Series bearings are available in single- or double-row configurations. Where space is absolutely minimal, single-row designs provide excellent performance. For applications requiring even higher load capacity, double-row (ZW) designs double the radial load capacity compared to single-row bearings.
