SUMMARY

Cylindrical roller bearings are designed to carry heavy radial loads and operate at high speeds. Featuring cylindrical rollers in linear contact with the raceways, they offer high rigidity and load-carrying capacity. These bearings are available in various designs such as NU, NJ, NUP, and N types, allowing for axial displacement or fixed positioning. They are widely used in gearboxes, electric motors, machine tools, and steel machinery. Our cylindrical roller bearings ensure low friction, stable performance, and long service life under demanding conditions.

Q & A

 Are you a trading company or a manufacturer?

We are not only a professional bearing manufacturer, but also a highly experienced trading company.
This enables us to supply a wide range of bearing products — both those we produce ourselves and those sourced from reliable partners — to meet diverse customer needs.

 Can I visit your factory? 

Sure, you’re welcome to visit our factory anytime!
Just let us know your schedule in advance, and we’ll arrange everything for you.

Can we take some samples? Any fees?

Yes, we can provide free samples, but the shipping cost is on your side.
If you place an order after confirming the sample, we will refund the shipping fee or deduct it from the order total.

What are the loading ports?

Our primary loading port is Qingdao, but we can also ship from Shanghai, Tianjin or other ports in China as needed.

Is there quality inspection before loading?

Of course. All our products undergo strict quality inspection before packing. Any that do not meet the standards are rejected and discarded.
Customers are also welcome to arrange third-party inspections before loading.
