To begin, check the markings. An absence of markings is an obvious sign that the bearings are fake. If markings are present, are they similar to standard manufacturer markings, or are they located on different areas of the bearing to normal? Both can point to illegal manufacture.

NSK commenced manufacturing of bearings in China in 1995 with the establishment of Kunshan NSK Co., Ltd., located in greater Shanghai. Since then, NSK has expanded its business in China in line with the country's economic growth, setting up 12 factories.
(日本精工株式会社, Nippon Seikō Kabushiki-gaisha, Japan Precision Company), also known in some markets as NSK Automation, is a large manufacturer of bearings globally and the largest in Japan.
NTN's tolerances are tighter than SKF's. It has nothing to do with the seals. Bearing life is all to do with the tolerances. bm0p700f wrote: NTN's tolerances are tighter than SKF's.
The bearings are marked SKF....made in China.
The code for the bearing bore indicates the bearing's bore size. A two-digit number is used for bore sizes from 20 mm to 480 mm. This number is multiplied by five to give the bore size. For example, code 6224 stands for a deep-groove ball bearing with a bore size of 120 mm.

Are there fake Koyo bearings?
Counterfeit products are generally produced by non - certified bearing manufacturer and marked “Koyo” brand logo on their products. As the products are not produced to meet Koyo technology and internal specification, there are huge risk of very poor bearing performance and premature failure.
Cylindrical Roller Bearings
They also offer excellent stiffness, axial load transmission, low friction, and a long service duration.
Select the right bearing type based on the magnitude and direction of the load. Select a bearing that matches the dimensions of the shaft or housing from the bearing boundary dimensions table.
NSK was founded in 1916 and produced the first ball bearings made in Japan. Since then, the company has spearheaded the development of bearings in Japan. NSK now offers a full range of bearings and sells them worldwide.
If you are looking for just the right plastic-bearing made with world-famous Japanese care and service that can't be found anywhere else, the answer is Kashima.
See NSK's history since 1916 as the first maker of ball bearings in Japan.
A “V-shaped” marking on the outside surface of the outer rings of universally matchable single direction bearings indicates how the bearing set should be mounted in relation to the axial load. The “V-shaped” marking points toward the side face of the inner ring that can support axial load.
2RZ bearings are like 2Z bearings, but also have two low-friction seals.
SKF bearings are some of the highest quality bearings on the market.
SKF USA Inc. is the US subsidiary of SKF Group, a world leader in rolling bearings and related technologies including sealing solutions, lubrication systems, and services.
What is the biggest bearing in the world?
The world's biggest ball bearing in use is 12 feet in diameter and weighs between 40,000 to 50,000 pounds, a pretty impressive size, but it's arguably the tiniest ball bearing in the world which is the most astonishing feat of engineering. Small bearings don't come much smaller than this one.
Whether a heavy-duty or performance, Clevite TriMetal remains the industry standard in bearings. Typically, they can withstand up to 60% higher loads and have 40% better seizure resistance than comparable competitive engine bearings.
H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. They're also available with either 180 degree or 360 degree oil grooves, as well as an extra 0.001 in.
CLEVITE BiMetal engine bearings feature a 100% lead free aluminum silicon bi-metal material, which includes 60% more silicon than the leading competitor's bi-metal material for better conditioning of journal surfaces.
A narrow bearing is required when using a crankshaft with a large fillet radius. On a crankshaft, The area where the bearing rides is called the Journal. The surface of the counterweight is called the Cheek. The Fillet Radius is the area where these parts meet.
