Customization Options
Different thread precisions can be provided to meet various precision application requirements.

Left-hand Thread Version
For left-hand thread models, please add "L" or "LH" after the bearing model number, for example: SALZJ12 1/2 20UNF 2ALH.

Material Options:
The rod end body and inner ring of this series can be made of stainless steel, suitable for applications requiring higher corrosion resistance. An "X" is added after the model number to indicate the stainless steel version, for example: SAZJ…/X.

Applications:
SAZJ series rod end spherical plain bearings are widely used in various equipment requiring high precision, high rigidity, and long-term durability, and are particularly suitable for industrial robots, medical equipment, aerospace, and precision instruments.
