A grease lock seal with sealing lips angled inwardly towards the internal bearing components is press fit into a bearing cup assembly to prevent grease from being purged due to centrifugal forces introduced during the rotational operation of the system. As the plurality of sealing lips retain grease in the system, the system does not have to be re-greased. If one desires to re-grease the system, the grease lock seal can further include a plurality of grease purge channels which create a path for used grease to be purged. As internal pressure increases during regreasing, the used grease flows through the grease purge channels and out of the system. However, the grease purge channels are small enough so that grease does not escape from the system during normal operation.
