Koyo/JTEKT Shell Type WJ-162116/KOYO | AIMS Industrial

• Unitized design simplifies handling and installation while allowing for increased lube flow.
• Split and segmented designs allow mounting at difficult positions on crankshafts and gear shafts.
• Controlled contour rollers optimize contact stress distribution.
• Special manufacturing processes help increase roller fatigue resistance and minimize axial drift effects in critical applications.
• Optimized cage piloting geometry minimizes pressure velocity effects.
• Steel or polymer cages are available to suit your application requirements.
• Coatings are available to help avoid corrosion and improve wear resistance.
