Super Precision Angular Contact Ball Bearings 7030 CD/P4ATBTC

Super Precision Angular Contact Ball Bearings 7030 CD/P4ATBTC

The 7030 CD/P4ATBTC is a super precision angular contact ball bearing with a 150mm bore and 225mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 83475 lbf and operates smoothly at speeds up to 11000 RPM.

Its 15° contact angle and matched set of three bearings (TBT arrangement) provide stability for angular loads, while the phenolic cage ensures quiet performance. The moderate preload (Class C) enhances precision in demanding applications.

This bearing suits high-speed machinery like spindles or CNC equipment, where accuracy is crucial. It works in temperatures from -30°C to 110°C and comes pre-lubricated for immediate use.

Weighing 12.5kg, it’s robust yet designed for precision. Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades. The open design allows easy maintenance when needed.
