Product Overview: The 63308 Double Row Angular Contact Ball Bearing
The 63308 bearing is a high-capacity component, functionally equivalent to a 3308 bearing, and is a key part of our 3300 Series of Angular Contact Ball Bearings. With its core dimensions of 40x90x36.5mm, this bearing is engineered to handle combined radial and axial loads in both directions simultaneously. Its back-to-back arrangement of two single-row angular contact bearings provides a compact, rigid, and high-capacity solution for applications where shaft space is limited and high stiffness is required.
Manufactured from high-quality bearing steel, the 63308 is designed for durability and precision. This double row design eliminates the need for paired single-row bearings, simplifying installation and reducing the potential for mounting errors. It is an indispensable part in various heavy-duty industrial and automotive applications where reliable performance under complex load conditions is critical.
Key Features of the 63308 Bearing
- Double Row Design: Provides high load-carrying capacity in a compact design, equivalent to two single-row bearings.
- Bi-Directional Axial Load Support: Capable of accommodating axial loads in both directions, making it highly versatile.
- High Rigidity: Offers excellent stiffness, making it ideal for applications that require precise shaft location and resistance to tilting moments.
- Combined Load Capability: Efficiently manages both radial and axial forces acting on the shaft.
- Simplified Mounting: The one-piece design is easier to handle and mount compared to a matched pair of single-row bearings.
- Durable Construction: Made from premium-grade, through-hardened bearing steel for extended service life and reliability.
Common Applications for 63308 Bearings
- Industrial Pumps: Provides robust support for pump shafts, handling the combined loads typical in fluid handling systems.
- Compressors: Used in various types of compressors to support rotating components under high pressure and speed.
