If you read the Forbes report it specicically states what the plant is for:
"The new plant will be a joint venture with a Chinese entity to install interiors and paint exteriors on 737 airliners, Boeing’s popular single-aisle jetliner that competes with the Airbus A320."
Not bearings. However, the Chinese offset incentive for cost savings to have Boeing build their planes in Seattle using TPAC's bearings is the bottom line so whether it's built in the USA or China, Boeing will build using TPAC's bearings.
