Jihyeon Minh Dung Kim : 안녕하세요 :) 영상 잘 보았습니다. 혹시 25:32에 나오는 'orbital path'가 의미하는 개념이 무엇인지 설명 부탁드려도 될까요? offset되었다는 말도 함께 설명해 주시면 감사하겠습니다 ㅎㅎ
국밥아저씨 : 굿

ryan Molina : I really thank you, what you are doing is really important keep creating awesome content like this !!!!!!!
truongcan89 : I love this video. Very very informative. Thanks for explaining so well.
Anas Gheith. : Excellent videos overall. God bless.

Kindly note that at 6:06 I heard "...to select a gear...". I hope it is worth mentioning.
Mixter Muxter : absolute life saver
Mohammad KSA : Thank you, you made my life easy

Renold Trapped Roller Clutch

Renold manufacture a wide range of Freewheel devices. These include Sprag, Trapped Roller and Ball-Bearing types, either as standard catalogue products, or customised designs to your exact requirements.

We offer a complete range of high quality, trapped roller clutches which have three basic operations, overrunning, Indexing, and Backstopping.
Copernicus : Oh my god what a wonderful explanation of a one way bearing
Doc02864 : I need a one way clutch for a hand powered bicycle.  This design seems perfect, just not sure about the longevity.  I actually need a pair to work in unison, one for the pushing action, one for the pulling action.
Fred Johnson : Do these transmit radial loads? Do you need to use a needle roller bearing with them?
gaurav kumar Gupta : Can we use this bearing for indexing table by rack and pinion mechanism through pneumatic cylinder.
Berg Mann : This method will make the balls heat up because they are rotating in place
