For tight radial spaces that still need to carry significant load, the NTN NK series needle roller bearing is a single-row radial unit supplied without an inner ring. It uses a steel cage and guided needles. You will find it in machine tools, pumps, compressors and transmission equipment. MR Industrial Accessories quotes by exact part number or size.
Reading an NK part number is straightforward once you know the pattern. The letters NK mean a needle roller bearing with no inner ring. The numbers that follow give bore and width. Take 8E-NK26/16RCT: the 8E prefix marks a design variant, NK26/16 sets the size, and RCT shows special sealing. Keep the order and separators exactly as written when you inquire.
These bearings suit metalworking, food processing and petrochemical plants where rotating equipment must stay compact. Typical spots include machine tool spindles, centrifugal pumps, screw compressors and gearboxes. Because there is no inner ring, the shaft itself serves as the raceway. That requires the shaft surface to have the right hardness and roughness.
Selection comes down to radial load, speed and the space you have. The RCT seal keeps contaminants out and lubricant in, which helps in dusty or damp areas. During assembly, check shaft and housing alignment, and confirm the shaft raceway meets the hardness requirement. Grease or oil both work, depending on the application and service conditions.
When replacing a bearing from another maker, the NTN NK series often crosses to equivalent designations that use the same nomenclature. Always verify critical dimensions and sealing type before swapping. MR Industrial Accessories can help you find a safe equivalent.

Frequently asked questions
- What does the RCT suffix mean in an NK bearing?
- The RCT suffix points to a design with special sealing. That seal blocks contaminants and helps retain lubricant. Include the full part number in your inquiry so compatibility is checked correctly.
- Does this bearing need an additional inner ring?
- No. The NK bearing mounts directly on the shaft, which acts as the raceway. The shaft must have suitable hardness and roughness for proper operation and long service life.
- How do I request a quote for a specific NK bearing?
- Send the complete part number or the exact size via WhatsApp. MR Industrial Accessories quotes promptly and can suggest a compatible alternative if needed.
