The 7018 ACDGD/P4A is a super precision angular contact ball bearing with a 90mm bore and 140mm outer diameter, crafted from high-quality chrome steel. It handles heavy radial loads up to 16672 lbf and operates smoothly at speeds up to 15000 RPM.
Its 25° contact angle and heavy preload (Class D) ensure stability under demanding conditions, while the phenolic cage reduces friction. The open design allows for easy lubrication and maintenance.
This bearing is part of a matched set of three, suitable for universal mounting (back-to-back, face-to-face, or tandem). Ideal for high-precision applications like machine tool spindles or industrial gearboxes.
Weighing 1.16kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it offers reliable performance in temperatures from -30°C to 110°C. Interchangeable with SKF bearings for easy replacement.
