Meet the Square Ball Universal Joint®
CCTY Bearing Company’s Application Design Team has developed a smoother, stronger bearing for intermittent applications. The square ball is capable of transferring torque through misaligned applications.
A square ball has redesigned the century-old universal joint. Below are 3 advantages of the Square Ball Universal Joint ® (SBJ) in steering applications over u-joints with needle bearings:
Larger Load Zone
Universal joints with needle bearings are subject to line load fretting on the raceways from continued vibration, reducing the expected service life.
Low Starting & Operational Torque Resistance
Starting rotational torque of a SBJ is very low, ranging from 0 to 0.025Nm when the operating angle range is 0 to 25 degrees. Since there are only 3 moving parts, starting torque is consistent.
Boot Sealed Design
All moving components are lubricated and maintenance free.
An international and US patent for the SBJ has been received:
