Same companies that manufacture and sell bearings, prime example being SKF and resellers of SKF products.  I always source bearings and seals from the nearest bearing supply specialty store rather than order the same item via a motorcycle part number.  It saves money and time.  Many of the seals and bearings commonly used in motorcycles are also found in marine engines, farm equipment and industrial material handling like conveyor belts.  Take the worn parts into a bearing supply store and they can usually offer replacements on spec.

All sorted thanks everyone seal cost £1
