    2018-5-7 · The skew is mainly caused from the friction force at the roller end-rib contact. In our studied tapered roller bearing, the skew angle is calculated with a range between 0.025° and 0.5°. It has been observed that the skew is influenced by some operating conditions as well as the lubricant properties.
