Product Overview: The NK 1620 Needle Roller Bearing
The NK 1620 is a high-capacity machined ring needle roller bearing, a distinguished member of our NK Series. With principal dimensions of 16mm bore diameter, 24mm outer diameter, and 20mm width, this bearing is engineered for applications requiring high radial load support within a minimal space. As a type of Machined Ring Bearing from our extensive Needle Roller Bearings collection, the NK 1620 is designed without an inner ring. This allows it to use a hardened and ground shaft as the inner raceway, resulting in a compact, rigid, and cost-effective bearing arrangement. Its robust construction ensures reliable performance in demanding industrial and automotive environments.
Features of the NK 1620 Bearing
- Compact and Lightweight: The design without an inner ring provides a very low cross-sectional height, ideal for space-constrained applications.
- High Radial Load Capacity: Features a full complement of needle rollers, providing a large contact surface to handle significant radial loads.
- Machined Outer Ring: The solid, channel-shaped outer ring is precision-machined for high strength and rigidity, suitable for heavy-duty applications.
- Direct Shaft Mounting: Designed to run directly on a properly hardened and ground shaft, which serves as the inner raceway.
- Cage-Guided Rollers: Equipped with a cage that precisely guides the needle rollers, allowing for higher rotational speeds and reduced friction.
- High Operational Precision: Manufactured to tight tolerances to ensure smooth and accurate rotation.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts in transmission systems.
- Automotive Transmissions: Used in clutch assemblies, planetary gear sets, and other transmission components.
- Two-Stroke Engines: Ideal for use in connecting rod big ends and wrist pins where space is limited and loads are high.
- Power Tools: Found in drills, saws, and grinders, offering durable performance in a compact form.
- Pumps and Compressors: Supports rotating shafts, ensuring efficiency and longevity.
- Printing and Textile Machinery: Used in rollers and other moving parts that require precise, high-load support.
- Robotics and Automation: Enables compact and rigid joint designs in robotic arms and automated systems.
Benefits of Using the NK 1620 Bearing
- Maximized Space Efficiency: Its low-profile design allows for smaller and lighter machinery designs without sacrificing load capacity.
- Enhanced Rigidity: Mounting directly on the shaft creates a very stiff bearing arrangement, improving overall system stability.
- Cost-Effective Assembly: By eliminating the need for a separate inner ring, it reduces component count and simplifies the overall design.
- Superior Performance: Offers excellent reliability and a long service life even under high loads and continuous operation.
- Reduced Maintenance: The durable construction and high-quality materials minimize wear, leading to fewer maintenance intervals.
- Efficient Operation: The caged roller design minimizes friction and heat generation, contributing to better energy efficiency.
