Press it out. Or tap it out. The clearances of the blocks are normally quite loose. Those bearings are as common as chips. When I buy them I buy 10 at a time off the Chinese sites for $20. The markings will relate to the size type and type of seal. Off memory your one is a 30mm x 8mm x 12mm. When you measure it you only need call around and give those measurements to replace it. I would be surprised if you can't find one within 20km of home. B
