company news about Introduction to the 7602015 B 2RZ P4 DB Thrust Angular Contact Ball Bearing

The 7602015 B 2RZ P4 DB is a thrust angular contact ball bearing specifically engineered for high-precision axial load applications, commonly used in machine tool spindles, ball screws, and other precision equipment. Manufactured to tight tolerances and built for high-speed performance, this bearing combines axial rigidity, high dynamic load capacity, and low-friction operation in a compact form.

Bearing Designation Breakdown

Let’s break down the meaning of the bearing code:

• 7602015 – Bearing series and size:

  • Bore diameter: 15 mm

  • Outside diameter: 35 mm

  • Width: 11 mm

• B – Design variant with optimized internal geometry for axial stiffness.

• 2RZ – Non-contact rubber seals on both sides for low-friction sealing, helping to retain lubricant and protect from contamination.

• P4 – Super-precision tolerance class (ISO Class 4), suitable for high-accuracy spindle and screw drive applications.

• DB – Back-to-back paired configuration, allowing for axial load handling in both directions and improved rigidity.

Key Features

• Thrust Angular Contact Design: Designed primarily to handle axial loads, but can support light radial loads as well when mounted in pairs.

• High Precision (P4): Manufactured to tight dimensional and running accuracy for applications requiring high speed and minimal vibration.

• Back-to-Back Mounting (DB): Enhances moment load capacity and axial stiffness, making it suitable for high-performance ball screw supports.

• Sealed (2RZ): Helps protect against dust and debris while maintaining lubrication, reducing maintenance needs.

• Optimized Internal Design (B): Improved load distribution and higher axial rigidity.

Advantages

• Excellent performance under high axial loads

• High rigidity for accurate positioning

• Minimal runout for rotational precision

• Maintenance-friendly sealed design

• Reliable operation at high rotational speeds
