size: Inner diameter (d): 19 mm Outer diameter (D): 32 mm Width (B): 20mm Features: Strong load-bearing capacity: The LZ3224 bottom roller bearing adopts a double-row cylindrical roller structure. Compared with single-row bearings, it has a higher load-bearing capacity and can withstand greater radial and axial loads. Suitable for high-speed operation: Since the rolling elements of the LZ3224 bottom roller bearing are relatively long, it has a lower friction coefficient and smaller rolling resistance when rotating at high speed, making it suitable for high-speed operation applications. Good impact resistance: The rolling elements of the LZ3224 bottom roller bearing are evenly distributed and can share and absorb shock and vibration. It has good impact resistance and is suitable for occasions where the working environment is harsh or where impact loads need to be withheld. Suitable for heavy machinery: LZ3224 bottom roller bearing is suitable for heavy machinery equipment and engineering machinery, such as steel, mining, cement and other industries. Easy installation and adjustment: LZ3224 bottom roller bearings usually have an adjustable internal structure, and the axial position can be adjusted by adjusting the gap between the inner and outer rings, making installation and adjustment easy. Generally speaking, LZ3224 bottom roller bearing has the characteristics of strong load-bearing capacity, good impact resistance, and is suitable for high-speed operation. It is suitable for applications with heavy load, high speed, impact load, and high precision requirements.
