Standard self-aligning plummer block shaft diameter 20-140mm

Pillow block for self-aligning bearing

Standard self-aligning plummer block shaft diameter 20-140mm

Standard vertical self-aligning bearings with housings, available in shaft diameters ranging from 20 to 140 mm, feature a rational structural design and are simple and convenient to install. They offer excellent self-aligning performance, effectively compensating for misalignment during installation and coaxiality errors in the shaft system; They operate smoothly, distribute loads evenly and offer good wear resistance. Suitable for standard, dust-free operating conditions at ambient temperatures, they are widely used in support applications for conventional equipment such as light industrial machinery, conveying equipment, general-purpose transmission systems and agricultural machinery. With a comprehensive range of models and high versatility, they meet the installation and matching requirements for standard small and medium-sized shaft diameters.
