truck hard to move

Stop! You may ruin the shaft and have to buy a whole y motor pack. The bearings are standard metric 5X11X5 mm (685). For example:

Thanks bergerud,
Which would you go with the all metal ones or the ceramic and metal ones? Thanks Mike

I would go 685ZZ where ZZ is metal shield on both sides.

No cermaic. Just regular steel bearings. (Ceramic are for high speed.)

The Roller Rail Bearings can freeze up and the frozen bearing can slide along the rail fooling you as you move it. It is when it is under load of the belt drive that the head twists putting downward pressure on the frozen bearing acting as a brake and giving you the problem.

Sometimes you can flush out the roller rail bearings with WD 40 but be careful as the WD 40 can give you problems with wood finish if it gets on raw wood.

I recommend to mark the bearings with a marker to better see the movement or lack of movement.

Can you tell me the size of the screws . I have one that will need to be replaced the next time I have to change the Bearing.
