In textile machinery, the bottom roller bearing is a commonly used rolling bearing. The following is an introduction to bottom roller bearings used in textile machinery: Structural features: The bottom roller bearing adopts a double-row cylindrical roller structure, and both the inner and outer rings have a spherical structure. It has a large number of rollers and is evenly distributed, so it has a high load-bearing capacity and good impact resistance. Scope of application: Bottom roller bearings are widely used in textile machinery, such as spinning machines, looms, printing and dyeing machines, etc. They are typically used in applications where they are subject to large radial and axial loads. Advantages: The bottom roller bearing has the advantages of strong load-bearing capacity, good impact resistance, and low friction coefficient during high-speed rotation. At the same time, their internal structure is adjustable, enabling axial position adjustment, and is easy to install and adjust.
