Product Overview: The KK 202634 Needle Roller and Cage Assembly
The KK 202634 is a high-capacity, double-row needle roller and cage assembly, precision-engineered with principal dimensions of 20mm Bore Diameter, 26mm Outer Diameter, and 34mm Width. This component is a vital part of our Needle Roller and Cage Assemblies collection, designed to provide exceptional radial load support within a minimal space envelope. It consists of a cage that retains and guides two rows of needle rollers, forming a non-separable unit. Since it lacks inner and outer rings, it is intended for applications where the shaft and housing bore can be hardened and ground to serve as raceways. This design maximizes rigidity and load-carrying capacity, making it an excellent choice for demanding industrial applications. Explore our full range of Needle Roller Bearings for a comprehensive selection of high-performance solutions.
Key Features of the KK 202634
- Double-Row Design: Features two rows of needle rollers for significantly increased radial load capacity and rigidity compared to single-row designs.
- High-Precision Cage: The robust cage accurately guides the rollers, ensuring smooth operation, low friction, and uniform load distribution.
- Space-Saving Construction: By using the shaft and housing as raceways, it offers the smallest possible radial cross-section for a given load.
- Split Cage Assembly: Typically designed as a split assembly for simplified mounting, especially in applications like connecting rods.
- Optimized Roller Profile: Rollers are profiled to prevent edge stresses, increasing the bearing's service life under heavy or shock loads.
- Durable Material: Manufactured from high-quality bearing steel for superior strength, wear resistance, and long-term reliability.
Common Applications
- Two-Stroke Engines: Widely used for connecting rod big ends and small ends, where high loads and oscillating motion are present.
- Piston Pins: Provides reliable support for piston pins in internal combustion engines and compressors.
- Industrial Gearboxes: Supports planetary gears and other components where radial space is limited but load capacity is critical.
- Universal Joints: Ideal for the cross journals in universal joints, handling high torque and complex movements.
- Heavy Machinery Pivots: Used in pivot points for construction and agricultural equipment that experience high radial forces.
- Industrial Pumps: Ensures stable and efficient operation of reciprocating pump components.
- Printing Machinery: Supports rollers and shafts requiring high rotational accuracy and rigidity.
