High Precision Engineering

Manufactured with a P4 precision rating, the NSK 65 BNR 10 bearing guarantees exceptional rotational accuracy, making it suitable for high-precision CNC machine operations. Its 25 contact angle and angular contact design deliver outstanding support for ball screws, minimizing axial displacement and maximizing performance under heavy loads.

Versatile Mounting Configurations

This bearing accommodates face-to-face (DB), back-to-back (DF), and tandem (DT) mounting arrangements, offering flexibility for specialized machine tool assemblies. With its single-row angular contact construction and press fit or axial clamp mounting, installation and adaptation to various system requirements are straightforward and reliable.

FAQs of NSK BALL SCREW SUPPORT BEARING 65 BNR 10:

Q: How is the NSK 65 BNR 10 bearing typically installed in CNC machines?

A: The NSK 65 BNR 10 bearing can be mounted using press fit or axial clamp methods. It supports face-to-face, back-to-back, or tandem arrangements, allowing users flexibility depending on the axial and radial load requirements of their ball screw system.

Q: What benefits does the P4 precision rating provide for CNC applications?

A: The P4 precision rating ensures minimal dimensional tolerances and exceptional rotary accuracy. This translates into higher positioning precision, reduced vibration, and improved operational reliability, especially in high-speed, high-demand CNC environments.

Q: When should I use grease versus oil for lubricating the 65 BNR 10 bearing?

A: Grease is preferred for general or lower-speed use due to its ease of maintenance, while oil is recommended for high-speed applications (up to 9000 rpm) as it provides better heat dissipation and minimizes friction under demanding conditions.

Q: Where is the NSK 65 BNR 10 bearing best used?

A: This bearing is optimally designed for ball screw support in CNC machine tools but is also applicable in industrial machinery requiring high precision, high axial load capacity, and robust reliability.

Q: What is the process for selecting the correct mounting arrangement?

A: The choice between face-to-face (DB), back-to-back (DF), or tandem (DT) arrangements depends on the desired support stiffness, load direction, and thermal compensation needs. Consulting engineering guidelines or NSK technical support ensures optimal configuration.

Q: How does the phenolic resin cage benefit the performance of this bearing?

A: The phenolic resin cage reduces inertial mass, enables high-speed rotation, diminishes cage wear, and maintains excellent ball guidance, contributing to higher operational speeds and longer bearing life.
