Most likely others on this forum are aware of this, but after having replaced one of the wheels on my RT-700 because it was "bent", I realized the other day I am seeing a similar situation with the new replacement wheel. Then I remembered finding some strange small BB like looking balls on my garage floor... Bingo, the sideways pressure on the stem castors is opening up the ball bearing housing of the castor just enough to allow ball bearings to come out. This leads to a "leaning" effect on the castors when observed from a low angle.
In other words, the castors provided with the RT-700 aren't able to bear the combination of weight and sideways movement required to "spin" the castor on it's vertical axis. At least in my case that is proving to be true. Since I suspect, if I obtain another replacement castor from Recteq it will just do the same thing, I've been looking for a hefty enough replacement castor. If anyone knows of a castor with enough strength to handle the aforementioned stress please let me know.
Here are the specs on these castors:
Type: Threaded Stem Castor
Stem Length: 1.5"
Stem Width: .5"
Wheel Diameter: 3"
Total Height: 4" (From bottom of wheel to the base of the castor stem)
Thanks in advance for any suggestions.
P.S. I do not want to retrofit the entire wheel assemblies as mentioned in other threads - I just want an easy castor replacement if possible)
