7305 BE-2RZP Bearing Product Overview & Core Advantages
The 7305 BE-2RZP is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. This sealed precision bearing features a 40° contact angle, enabling it to effectively support substantial axial loads in one direction while handling significant radial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers high running accuracy and dimensional stability. Its compact design, with a 25 mm bore and 62 mm outside diameter, makes it ideal for space-constrained, high-reliability applications where high rigidity and precise shaft guidance are critical.

7305 BE-2RZP Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 40° contact angle and optimized internal geometry provide superior stiffness, enabling the bearing to handle significant combined radial and axial loads simultaneously. The calculated load point position ensures optimal force distribution.
Precision Performance: Manufactured to P6 tolerance class with precision-ground chrome steel rings and balls, this bearing guarantees high running accuracy, reduced vibration, and consistent performance in demanding applications.
Sealed & Lubricated Design: Equipped with non-contact 2RZ seals on both sides, the bearing is effectively protected from contaminants. Pre-lubricated with high-quality grease, it offers a wide operating temperature range from -30°C to 110°C and is suitable for high-speed operation up to 11,000 rpm.
Lightweight & Efficient: The nylon cage reduces weight and inertial forces, contributing to smoother operation at high speeds while maintaining excellent guidance and stability.
