When radial space is tight but loads are not, the SKF NX ZTN needle roller bearing delivers high radial capacity in a single-row, compact envelope. It fits machine tools, transmissions, pumps and general industrial equipment. MR Industrial Accessories supplies this brand and helps you match the right bearing to your application.
Reading the code helps you confirm a replacement quickly. NX marks the series: single-row needle roller bearings built to compact dimensions. The number after it is the bore diameter in millimeters, so NX 7 ZTN has a 7 mm bore. The ZTN suffix covers two features: an inner ring with a flange and a reinforced plastic cage. Together they ease mounting and keep the needles properly retained.
Use NX ZTN bearings where high radial load capacity must fit into minimal space. Typical installations include machine tool spindles, gearboxes, water and oil pumps, compressors, electric motors and automation equipment. Automotive components such as camshafts and transmissions also use them. The design handles high radial loads and moderate speeds, with a strong ratio between size and load capacity.
Selection comes down to bore diameter, required load capacity and lubrication conditions. Check sealing as well: in dusty or damp environments, look at variants with seals. Mount with suitable tools so the needles and cage are not damaged, and keep shaft-to-housing alignment precise to avoid extra loads. Grease or oil both work, depending on speed and operating temperature.
For equivalents, remember that needle roller bearings from different makers can carry different designations while using standardized dimensions. Compare bore diameter, outer diameter and width, plus load and speed characteristics. SKF products are often interchangeable with others built to the same dimensional standards. Review the technical specifications before substituting one brand for another.

Frequently asked questions
- What does the NX ZTN designation mean?
- NX identifies the series of single-row needle roller bearings with a compact design. The following number is the bore diameter in millimeters. ZTN means the bearing has an inner ring with a flange and a reinforced plastic cage, which eases mounting.
- Where is this type of bearing used?
- In applications with limited space and high radial loads, such as machine tools, pumps, compressors, electric motors and transmissions. It is also common in automotive components and industrial equipment that requires precision.
- How do I know if I can replace a bearing from another brand with this SKF one?
- Compare the main dimensions (bore, outer diameter and width) and the load and speed capacities. If they match and the design is equivalent, replacement is possible. Review the technical specifications or contact us for advice.
