Replacemenet sliding window roller

A home owner from Belgium says:
The sliding roller and housing;

ALLEN STEVENS CORP
WOODSIDE.N.Y.

Stamped in a circle reads; 60
49

The part is all metal,wheel included,the problem is that the wheel and its ball bearings has come apart..The casing is 5cm x 3cm (sorry don`t have a measure with inches)The diameter of the larger wheel or the two is 3.2cm and the small inner wheels diameter is about 1.6cm(its pretty damaged)
The casing has a swivel part that the wheel attatches to this also has a number stamp 6047
The width of the wheel is 8mm

I have attatched a few photos,and look forward to your reply..
