Vertical shaft mounting for bearings Evolution
2021.9.22 Understanding vertical shaft mounting for bearings. When mounting bearings, one of the most common procedures is to use a vertical shaft mounting position and work with heat. Considering all common mounting methods, as many as one in six bearings may fail because of inadvertent damage sustained during mounting.

Torque calculations: Rotating vertical shaft - Physics Forums
2021.7.21 The formula for frictional torque can be approximated for angular contact bearings to: T (fr) = 0.5 * μ * radial load (N) * bearing bore (m) μ = 0.002 for angular contact ball bearings (this is low because there is lubrication and non-contact seals) so the frictional force in reality acting between shaft and the lubricant.

Seismic response of vertical shafts in multi layered soil using
vertical access areas connected to deep horizontal tunnels (Jeong et al. 2010, Kim et al. 2013, Lee et al. 2016). Therefore, vertical shafts have a higher risk under seismic loading as compared to horizontal tunnels since the vertical shaft is vertically constructed in the multi-layered soil that Corresponding author, Ph.D., Professor
