About INA
Almost every modern passenger car contains an INA engine and transmission component. INA is a global manufacturer of OEM (Original Equipment Manufacturer) roller bearings, linear motion, engine components, plain bearings and precision components meaning that the original parts removed from your car will most likely have INA stamped right on it.
Today INA is a division of the Schaeffler Group, which also includes FAG and LuK, they are the second-largest bearing manufacturer in the world. Their bearings are used in the space shuttle and the Millennium Wheel in London. Schaeffler has manufacturing facilities all around the world including Danbury CT.

OE
This is the original part used by the vehicle manufacturer when it left the factory - in other words, a Genuine product without the logo on it and without the premium cost. We recommend OE replacement as best options for quality and price. Vehicle manufacturers (BMW, Volvo, etc.) do not manufacture many products themselves, rather they contract their Original Equipment Manufacturers to do so. The products that we list as OE are guaranteed to be the exact same part that was on your car when it left the assembly line. In some cases they are even better quality than what is currently available in Genuine because over time some Genuine contracts get changed to save money. All of these parts will be stamped with the OEM’s brand name such as Bosch, Hella, or Lemforder but due to contractual agreements the vehicle manufacturer’s logo cannot be on the product and may be removed from the part.
