We carry the a grease seal that matches what you have. For that you would want the # BB60002.

For the bearings we have the part # 29749 and the race part # 29710.

For the other bearing we do not have an exact number match, but based on the race # L44610 that you have the bearing you need is either the # L44643 or # L44649.

If the inner diameter of the bearing you have is 1.00 inches measured with a digital or dial caliper you would need part # L44643, if instead it is 1.06 you would need # L44649.
