Bearing preload: What is it and why is it important

Jun 11 2019Contact anlgle for angular contact bearing Source Kayden Bearing Contact angles for deep groove radial bearings are small measuring 8 or less Angular contact bearings are machined to have larger contact angles when preloaded typically 15 25 30 or 40 The amount of the contact angle is predetermined and designed into the bearings

Help with physics homework?

Mar 26 2010At serve a tennis player aims to hit the ball horizontally What minimum speed is required for the babll to clear the 0 90 m-high net about 15 0 m from the server if the ball is launched at a height of 2 50 m? where wil the ball land if it just clears the net? How long will it be in the air? Thanks!
