Super Precision Angular Contact Ball Bearings 7048 CD/P4ADGA

Super Precision Angular Contact Ball Bearings 7048 CD/P4ADGA

The 7048 CD/P4ADGA is a super precision angular contact ball bearing with a 240mm bore and 360mm outer diameter, crafted from high-grade chrome steel. It handles radial loads up to 125775 lbf and operates smoothly at speeds up to 7500 RPM.

Its 15° contact angle and universal matching design allow flexible arrangements like back-to-back or face-to-face, ideal for complex setups. The phenolic cage ensures durability while keeping weight manageable at 34.2kg.

This bearing excels in high-precision applications such as machine tool spindles or aerospace systems, where tight tolerances (P4A class) matter. It works reliably in temperatures from -30°C to 110°C.

Pre-lubricated for easy use, it’s interchangeable with SKF bearings for straightforward replacements. The open design simplifies maintenance, and its matched set of two bearings offers versatile mounting options.
