The rotor spindle bearing 73-1-22 is a composite bearing composed of a variety of bearings, easy to install and maintain, mainly used in pneumatic textile machinery.
The rotating cup 73-1-22 bearing has the advantages of high carrying capacity, good durability and high speed. The maximum working speed of 73-1-22 reaches 72000 RPM, and the size parameters are D: 22mm d:10mm L:112mm L1:56mm M:18mm.
The design of the rotor spindle bearing takes into account a variety of factors, such as the addition of dust grooves and dust rings at both ends to avoid the entry of oil spills and debris. The outer ring is designed to be coated with oil, which can be added in time to reduce the wear of the cup bearing.
The rotor spindle bearing is a standard bearing that plays an important role in textile machinery. FTM can produce rotating cup bearings according to the model, and can also customize the accessories required inside, such as deep groove ball bearings, shafts, rings, rotating cups, etc. The rotor of the rotor bearing can also have different choices for surface plating, such as surface plating: nickel, diamond, to meet the needs of the spinning machine equipment

The 73-1-22 Rotor Spindle Bearing is a high-precision composite bearing assembly specifically engineered for the demanding environment of pneumatic textile machinery. As an essential component in open-end spinning systems, this spindle facilitates the high-speed rotation required to twist and wrap fibers into yarn with consistent tension and quality.
Designed to thrive under high-stress conditions, the 73-1-22 model supports a staggering maximum working speed of 72,000 RPM. Its robust internal geometry provides a superior carrying capacity, ensuring that the spindle remains stable even during continuous, long-shift operations.
To maintain peak performance and extend service life, the 73-1-22 features a sophisticated protection system. Dual-end dust grooves and specialized dust rings act as a barrier against debris and fiber lint, while preventing oil leakage. Furthermore, the outer ring is designed with a dedicated oiling channel, allowing for seamless lubrication maintenance to significantly reduce frictional wear.
With over 30 years of technical expertise, Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM) provides more than just a standard part. We offer a comprehensive engineering solution:
1. Can the 73-1-22 bearing be customized for specific textile machines
Yes. While the 73-1-22 is a standard model, FTM specializes in customization. We can adjust internal clearances, modify shaft lengths, or change the rotor cup material to suit your specific equipment needs.
2. What are the benefits of the diamond-coated rotor option
The diamond-coated surface significantly increases the hardness and reduces the friction coefficient of the rotor. This is particularly beneficial when processing synthetic fibers or high-speed applications where abrasive wear is a concern.
3. How does the lubrication system work in this model
The outer ring is designed with integrated oiling features. This allows technicians to replenish lubricant without disassembling the entire unit, ensuring the bearing remains cooled and lubricated during high-speed rotation.
4. What measures are taken to prevent contamination in textile environments
Textile mills are prone to lint and dust. Our 73-1-22 bearing includes specialized dust rings and grooves at both ends to seal the internal components, preventing debris from entering and oil from escaping.
5. Why choose FTM over other bearing suppliers
FTM brings over three decades of design experience. We focus on non-standard and high-precision bearings, meaning our manufacturing tolerances are tighter than standard industrial grades, resulting in smoother operation and a longer replacement cycle for your machinery.
