Precision and Performance: P4/P2 Class

Engineered within super precision P4/P2 classes, the 45BNR10 ensures accuracy at high speeds, a critical aspect for advanced machine tool operations. The 25 contact angle provides superior axial thrust capability, which is essential for ball screw support in demanding industrial machinery.

Robust Structure and Materials

With a steel body, phenolic resin cage, and single-row angular contact design, the 45BNR10 combines toughness with longevity. The material selection not only supports heavy loads but also minimizes wear, translating into a prolonged service life and consistent machine tool performance.

Application and Mounting Flexibility

Designed for use in machine tool ball screw supports, the 45BNR10 features face mounting for easy installation. Its versatility is enhanced by options in sealing (open or sealed type), making it suitable for a variety of environments and maintenance regimes.

FAQs of NSK BALL SCREW SUPPORT BEARING 45 BNR 10:

Q: How is the NSK 45BNR10 bearing typically mounted?

A: The NSK 45BNR10 bearing utilizes a face mounting method, allowing it to be easily and securely installed in ball screw support assemblies of machine tools.

Q: What benefits does the 25 contact angle provide in ball screw support bearings?

A: A 25 contact angle in the 45BNR10 enhances its ability to support significant axial loads, which is essential for the precise linear motion required in machine tool applications.

Q: Where is the 45BNR10 bearing commonly used?

A: This model is specifically designed for ball screw support in machine tools, where high precision, speed, and load capacity are crucial for efficient and accurate operation.

Q: What is the recommended process for determining load ratings?

A: For accurate static and dynamic load ratings of the 45BNR10, it is advised to refer directly to NSKs data sheets or consult their technical support, as these figures may vary based on application specifics.

Q: What advantages does the phenolic resin cage offer?

A: Phenolic resin cages provide lightweight yet sturdy support for the bearings rolling elements, promoting high-speed stability, reduced friction, and improved life under demanding operating conditions.

Q: When should you choose the sealed type option for the 45BNR10?

A: The sealed version is recommended when enhanced protection against contaminants is necessary, especially in hostile or high-maintenance environments, to further increase bearing longevity and reduce downtime.

Q: What limiting speeds should users observe for this bearing?

A: When using grease lubrication, the limiting speed is 8,500 rpm, while with oil lubrication, it is up to 12,000 rpm. Operating within these limits maximizes performance and durability.
