Say No to counterfeits,
Is your life worth the gamble on fake bearings

What are counterfeit products?

Counterfeit products marked with Koyo, an important trademark and bearing brand of JTEKT, in particular, have been found in world markets.

Specific examples of counterfeit product damage

Counterfeit products that elaborately mimic individual boxes, engraved marks, etc., make it difficult to discriminate them from genuine products at a glance. In many cases, such counterfeit products have safety and quality problems.

Examples of confirmed counterfeit bearings are shown here.
In the future, this website will introduce durability test data that will convey the risks of counterfeit products.

The JTEKT Group would like to ask you to purchase genuine JTEKT products from the JTEKT Group or its authorized distributors in order to protect your safety.
