Help with front wheel bearing

Took the Jonway for it's mot. Guy says it needs new front wheel bearings.
On the wheelbearing it says 020155. Is this the size part number or what. They seem ok to me but I am not an expert. Any idea what size we need

Measure the bearing inner diameter, outer diameter and thickness.
Go to Simply Bearings online.
There is a box at the top of the screen where you can input the numbers and it will pull up all the options for that size bearing.
You need shielded bearings, not open ones.
Chip as chips, first class delivery. I normally get mine next day.

 

Thanks for that Steve. Have just ordered a set of vernier calipers, so will do that when they arrive. Just had a quick look on google, and we have auotsport wheel bearings where I live so will see what they can do.

 

Just take them to a bearing supplier, they'll match them up. 6201-6202 are most common.

 

Cheers for that Marsh. Yes when I found that I actully had a spares place on my doorstep, I decided that was what I would do.
