fits model: Cr.

( Part Type: Bearing ), ( Manufacturer Part Number: NJ307 )
The CR NJ307 bearing, specifically model 9W FTFT-FT, is a precision machine element designed for high load capacities and robust performance. Measuring 9mm in width, this deep groove ball bearing affords exceptional load carrying capacity due to its large diameter outer ring and thick rings. Its MT1307 series designation denotes its compatibility with shafts having an outside diameter of 13mm and a pitch diameter of 7mm.
Crafted with high-quality steel alloys, this CR NJ307 bearing is known for its strength and resilience. The inner and outer rings, along with the cage and balls, are individually engineered to harmonize with one another, ensuring minimal play for optimal efficiency. The deep groove design of the bearing offers better load distribution and enables higher speeds, perfect for demanding industrial applications.
The bullgear and housing collar contour of this bearing provide additional clearance for shock loading and heavy radial loads, further enhancing its suitability for industrial machinery. To ensure a secure installation and precise axial alignment, the CR NJ307 bearing incorporates a variety of locking methods, including set screws and collar nuts. Due to its large contact angle, this deep groove bearing delivers more load capacity per bearing than equal size cylindrical roller bearings or angular contact ball bearings, making it a cost-effective solution for heavy-duty applications.
In summary, the CR NJ307 bearing 9W FTFT-FT, with its 7mm pitch diameter, 13mm shaft compatibility, and capability to handle heavy radial loads, is a reliable and robust precision component that delivers enhanced performance and durability, making it perfectly suited for industrial machinery.
The CR NJ307 bearing (9WT, FTFT, M1307) is a popular choice among hobbyists and DIY enthusiasts for various applications, particularly in skateboards, go-karts, or machine tool usage.
II. Pros:1. Durable: CR bearings are known for their high strength and durability. They can withstand rough use without wear and tear, making them an excellent choice for high-impact applications.
2. Smooth Performance: CR bearings offer excellent rolling performance. This results in efficient use and reduced energy loss.
