A set of two high-precision angular contact ball bearings NTN 7914UCDB/GNP4 is designed for reliable back-to-back mounting. With an inner diameter of 70 mm, an outer diameter of 100 mm, and a total width of 32 mm, it provides excellent stability and precise shaft guidance.
This arrangement effectively accommodates both axial and radial loads in both directions, which is particularly useful for precision spindles and demanding machine tools. The factory-set light preload carefully eliminates clearances, thereby increasing the overall rigidity of the assembly without an undesirable increase in friction.
Technical Advantages and Details
- 15° Contact Angle: Ensures optimal kinematics and smooth operation even at very high speeds.
- P4 Precision Class: Guarantees exceptional dimensional accuracy and smooth running in accordance with the strict ISO 4 standard.
- Polyamide Cage: Effectively dampens vibrations and maintains reliable guidance of the steel balls.
- Open Design: The absence of seals facilitates rapid lubricant distribution directly to the rolling elements.
When installing the NTN 7914UCDB/GNP4 set, we recommend ensuring absolute cleanliness of the assembly unit and correct orientation of the rings. Appropriately selected lubricant and precise fitting will ensure a long service life and flawless operation of your machine.
