NTN BK series spherical roller bearings handle high radial loads while allowing the shaft and housing to sit at an angle to each other. Two rows of rollers run on a spherical outer raceway, so small mounting errors or shaft flex do not cause early failure. They suit equipment where alignment is not perfect, including conveyors, mills, crushers and large process machines.
The part number tells you most of what you need. Digits after the slash give the bore in millimeters; the prefix points to a dimension series; and the BK suffix covers construction details that NTN sets for each size, such as cage style or surface treatment. Reading these elements correctly is the first step when matching a replacement.
Typical duties include vertical mills, jaw crushers, vibrating screens, conveyor belts and high-power gearboxes, plus dryers and presses in pulp plants where continuous operation matters. The combination of combined-load capacity and misalignment tolerance fits equipment exposed to vibration or shock.
Selection starts with radial and axial load, speed and the operating environment. During mounting, check shaft-to-housing alignment: the bearing absorbs some error, but too much shortens its life. Lubrication, by grease or oil as specified, carries heat away and limits wear. For dirty or dusty locations, choose labyrinth seals or oil seals that keep contaminants out of the bearing interior.
Other makers following the same dimensional designation, such as SKF, FAG or NSK, can serve as equivalents, but tolerances and cage design may differ. Compare load capacity and service conditions before substituting. Our team can review the application data and point to a compatible option.

Frequently asked questions
- What does the BK suffix mean on NTN bearings?
- It marks a particular construction variant in the series and may relate to cage type, heat treatment or special tolerances. For the exact features of a given size, contact our technical team by WhatsApp.
- How do I choose the right spherical roller bearing?
- Review radial and axial load, speed, expected misalignment and environmental conditions. With those details we can help you select the correct part number. Write to us by WhatsApp.
- Are NTN BK series bearings interchangeable with other brands?
- They can be exchanged with bearings from other makers that use the same dimensional designation, such as SKF or FAG, provided tolerances and load capacity are checked. Send us the original part number and we will identify a compatible alternative.
