Product Overview: The NK 1420 Needle Roller Bearing
The NK 1420 is a high-performance machined ring needle roller bearing, designed with dimensions of 14x22x20mm (Bore Diameter x Outer Diameter x Thickness). As a key component in our NK Series, this bearing is part of the Without Inner Ring category of Needle Roller Bearings. This design is exceptionally compact, making it ideal for applications where radial space is limited. The NK 1420 uses a hardened and ground shaft as its inner raceway, which allows for a larger shaft diameter and greater rigidity. Its robust construction ensures high radial load capacity and reliable operation in demanding industrial environments.
Features of the NK 1420 Bearing
- Compact Design: The absence of an inner ring provides a minimal radial cross-section, saving valuable space in machinery.
- High Radial Load Capacity: Features a full complement of needle rollers, maximizing the contact area to support heavy radial loads.
- Machined Outer Ring: The solid, channel-shaped outer ring is precision-machined for high strength and durability.
- Shaft as Raceway: Designed to run directly on a hardened and ground shaft, simplifying the assembly and allowing for a more rigid arrangement.
- High Rotational Speed Capability: The precision engineering of the rollers and cage assembly allows for operation at high speeds.
- Versatile Application: Suitable for a wide range of industrial applications requiring compact and high-capacity bearing solutions.
Applications of NK 1420 Bearings
- Automotive Transmissions: Used in gearboxes, clutches, and driveshafts where space is at a premium.
- Industrial Gearboxes: Provides robust support for planetary gears and other transmission components.
- Two-Stroke Engines: Commonly found in connecting rod and piston pin applications.
- Power Tools: Ideal for use in drills, saws, and other handheld power equipment requiring compact, durable bearings.
- Pumps and Compressors: Supports rotating shafts in various types of pumps and compressors.
- Textile Machinery: Ensures smooth and reliable operation of moving parts in weaving and spinning machines.
- Office Equipment: Used in printers, copiers, and other machinery where precise, compact motion is required.
Benefits of Using the NK 1420 Bearing
- Space Efficiency: Enables more compact and lightweight machine designs due to its small radial footprint.
- Increased Rigidity: Using the shaft as the inner raceway allows for a larger, more rigid shaft, enhancing overall system stability.
- Cost-Effective Solution: Eliminates the need for a separate inner ring, reducing component count and overall assembly cost.
- Enhanced Performance: High load capacity and speed capability contribute to improved machine efficiency and output.
- Reduced Maintenance: The durable construction and high-quality materials lead to a longer service life and fewer maintenance intervals.
- Reliable Operation: Precision manufacturing ensures consistent performance and reliability even under heavy loads and high speeds.
