NX12Z Branded Full Complement Needle Roller Thrust Ball Bearing 12x21x18mm

Needle Roller / Thrust Bearing Combination: These combined bearings consist of a radial needle roller bearing with a thrust ball bearing. They are supplied without an inner ring but can be combined with an inner ring where the shaft cannot be hardened and ground (inner ring must be ordered separately). They are designed to accommodate axial loads in one direction and, therefore, locate the shaft in one direction only. Relatively high-speed operation can be permitted.
