Bearing preload: What is it and why is it important?

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. Angular contact bearings can carry both radial and axial loads ...

Tension Formula - Softschools

Tension Formula Questions: 1) There is a 5 kg mass hanging from a rope. What is the tension in the rope if the acceleration of the mass is zero? Answer: The mass, m = 5 kg; the acceleration, a = 0; and g is defined. T = mg + ma. T= (5 kg) (9.8 m/s 2) + (5 kg)(0) T = 49 kg-m /s 2 = 49 N. 2) Now assume an acceleration of + 5 m/s 2 upwards.
