Title: Prop shaft bearings.
Post by: Sonar on October 11, 2016, 04:19:19 pm
Hi Does any member know where I can buy some prop-shaft bearings.

The size I am looking for is for a 4mm internal shaft with an external tube of 6.0 mm to 6.50 mm

the size of the section that slides into the external tube is 5.50mm  4 required.

thats a very thin bearing, through the ball race, I would have thought the standard outer diameter of a 4mm bearing would be neared 8mm.
Maybe a specialist rc buggy / car size would do the job?

Probably best to renew the pair and be done with.
Least that way it is a std format for them.
