The rotor spindle bearing 72-6 is suitable for high-speed ring spinning machines. Its design and performance make it ideal for applications requiring high speed, low friction and radial loads, with a maximum operating speed of 90,000 RPM for the 72-6 and dimensions of D: 22mm d:8.9mm L:112mm L1:61mm M:13mm.
1. Textile machinery:
Especially in ring spinning machines, cup bearings are widely used to support high-speed rotating parts, such as cups and spindles. These machines require bearings to maintain stability and low wear performance at high speeds for long periods of time.
2. Industrial equipment:
In some industrial equipment, cup bearings are used to support the rotating shaft, especially in scenarios that require high precision and high efficiency operation, such as machine tools and automation equipment.
3. Small motor and transmission:
Some small motors or transmissions may also use this bearing to reduce friction and improve the efficiency of the machine.

FTM can extend the advantages of the cup bearing 72-6, so that it has the following performance
1. High speed performance:
Cup bearings are designed for high-speed operation and are stable at very high speeds. This is particularly important for equipment in the textile industry, because spinning equipment often needs to operate at high speeds for long periods of time.
2. Low friction:
Due to the special structure of the bearing, it produces low friction when rotating, thus reducing energy consumption and temperature rise, so that the life of the mechanical parts is extended.
3. Strong carrying capacity:
Despite their small size, cup bearings are able to withstand large radial loads, which is particularly useful in high-load industrial applications.
4. Compact structure:
The bearing design is relatively simple and compact, suitable for installation in mechanical equipment with limited space.
5. Durability:
Because the material used is usually high-quality steel, the rotary cup bearing has strong wear resistance and long life, reducing the frequency of maintenance of the equipment.
6. Precise positioning:
In textile machinery, cup bearings help to accurately position rotating parts, ensuring product quality and work efficiency.
