EFFECT OF PRELOAD OF ANGULAR CONTACT BALL BEARINGS ON LIFE OF BEARINGS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 Angular contact ball bearings are commonly used in such situations when you need to reach high bearing stiffness. However, a significant stiffness increase can be achieved only through the introduction of preload to the angular contact bearings.

Remora‐Inspired Sensing Suction Cup with Adhesion Monitoring and Force Detection
Advanced Intelligent Systems, EarlyView.A suction cup with integrated liquid metal microchannel sensors enables stable multidirectional force sensing and adhesion monitoring in both air and water. The flexible resistive sensors, placed on the outer lip, transduce deformations into resistance changes under normal and shear loads.

Topology Optimization for a Rigid‐Compliant Hybrid Constant Force Gripper
Advanced Intelligent Systems, EarlyView.Constant‐force grippers deliver near‐constant output without sensors, cutting cost and complexity. This study proposes a topology‐optimization framework jointly designing rigid links and material distribution, modeled via link‐state and element‐density variables with constant force as the objective.
