NTN tapered roller bearings are components designed to support combined radial and axial loads. Their raceway geometry and truncated-cone rollers distribute the load along a contact line, making them suitable for applications with moderate to high demands. They are used in industrial machinery, transport equipment and power transmission systems. MR Accesorios Industriales sells this NTN line.

The designation of these bearings combines numbers and letters that indicate design features. In the series in question, the numeric prefix indicates the size and dimensional series; the suffix CU identifies an execution with specific internal characteristics, while GD refers to the particular surface treatment or tolerance. The part numbers in this series correspond to tapered roller bearings with standardized dimensions and those variants. Understanding these suffixes is key to selecting the correct replacement.

In Argentine industry, these bearings are used in gearboxes, conveyor belts, road machinery, agricultural equipment and lifting systems. They also appear in machine tool spindles and in backup rolls of rolling mills. Their ability to support combined loads makes them common in applications where precision and rigidity are important. MR Accesorios Industriales supplies this line to workshops, factories and production plants throughout the country.

To select the right bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. Installation requires careful alignment and proper lubrication, either with grease or oil, as applicable. The sealing or protective plates must be chosen based on the contamination and humidity of the environment. Incorrect installation can reduce the bearing's service life and affect equipment performance.

NTN tapered roller bearings can be interchanged with those of other brands that follow the same standardized dimensions and equivalent designations. If you have another brand's part number, we can tell you the corresponding NTN reference. Interchangeability depends on tolerances and suffixes, so it is important to verify the exact equivalence. At MR Accesorios Industriales we advise you so that the replacement is reliable.

How do I choose the right tapered bearing for my application?
Consider the radial and axial load, speed, lubrication and environment. Also the type of mounting and alignment. With that data, we recommend the NTN reference that best suits you. Write to us on WhatsApp and we will help you.
Can I replace a bearing from another brand with an NTN one?
Yes, if the standardized dimensions and tolerances match. Interchangeability depends on the suffixes and execution. If you send us the original brand's part number, we will tell you the equivalent NTN reference and quote it for you.
