The NTN 812 series is a cylindrical roller thrust bearing built to handle high axial loads in one direction. Its cylindrical rollers and flat washers provide high load capacity and axial rigidity, making it suitable for applications that demand precision and durability. MR Industrial Accessories LLC supplies this series.
Reading the designation is straightforward: 812 identifies a single-direction cylindrical roller thrust bearing, and the J suffix indicates a stamped steel cage, which is standard for this series. For instance, 81218J is a cylindrical roller thrust bearing with the dimensions the manufacturer specifies for that size. Understanding this nomenclature helps you identify and select the correct bearing.
These bearings are found in gearboxes, machine tool spindles, pumps, compressors and lifting equipment, where considerable axial loads must be supported. They are common in metalworking, petrochemical and power generation operations, where robustness and axial load capacity are critical for continuous service.
Selection depends on the axial load to be carried, the operating speed and the environmental conditions. During assembly, the seat washers must be correctly aligned and lubrication must be adequate, whether grease or oil, according to the application. Check axial clearance and ensure firm fastening to avoid premature wear.
NTN cylindrical roller thrust bearings can be interchanged with those from other recognized brands, provided dimensions and load capacities are respected. Consulting a specialist to validate compatibility is recommended. MR Industrial Accessories LLC provides technical advice to find the best solution.

- The J indicates a stamped steel cage, which guides the rollers and is the standard design for the 812 series. Respect this feature when replacing the bearing.
- Does this bearing support radial loads?
- No, cylindrical roller thrust bearings are designed for predominantly axial loads in a single direction. For radial loads, use other bearing types such as radial roller or ball bearings.
- How can I request a quote for this product?
- Write via WhatsApp or email with the bearing code (for example, 81218J) or the dimensions you need. The team replies promptly and provides personalized technical advice.
