·Self aligning ball bearings are recommended for applications where aligning the shaft and housing is difficult or where the shaft may bend such as transmission shafts under normal loads; however such angles may not be allowable depending on the surrounding structure Features Correct for misalignment The inner ring balls and cage
aligning design of the ball bearing is attributed to Sven Wingquist of the SKF ball bearing manufacturer in 1907 In the year 2002 INA/FAG established by Dr Georg Schaeffler and Dr Wilhelm Schaeffler E1 spherical ball and roller bearing which is base of current modern rolling bearings Corresponding author
·The single row four point contact ball slewing bearing has a large structure and is subjected to heavy load which requires extremely high carrying capacity The structural parameters of the ball diameter and the number of balls are optimized with the fixed size of the inner and outer rings of the slewing bearing Numerical methods based on static bearing
Promoting our Slewing Bearing and Slew Drive to the middle and high end markets Our main products include Slewing Bearings and Slewing Drives with different structures The outer diameter range of our Slewing Bearing can be produced from 100 8000 mm and the materials are 42CrMo4 50Mn Gcr15SiMn Aluminum and Martensitic Alloy Steel
·PHS is a type of bearing with a unique structure Its inner and outer rings are made of high carbon chromium bearing steel which undergoes processes such as quenching grinding and coating The PHS bearing consists of a steel ball as the sphere which contacts a housing with a spherical bore providing support and guidance
