Bearing specs

[Robotstar5]

I was looking for replacement wheel bearings for a trailer and see they are available as standard or "C3" spec., C3 is for high speed applications and have some play until warmed up, would a wheel travelling at 50/60 mph be classed as high speed?.

No but C3 is normal for wheels as it's cheap to produce.

high speed if there's nothing in it pricewise u can go faster with heavy loads in my trailer can theoretically do 80mph fully loaded for 30 miles

Sloppy new bearings (6207-C3) in a Morris minor back axle will probably fail the MOT. I had to use CN clearance to be acceptable. These are the original spec for the rears.

A work colleague had similar problems with an old Jaguar where manual setup had play when cold, he had few problems at MOT time until he showed the tester the manual.
