B7018-C-T-P4S-UL

When it comes to maintaining high-speed stability in machine tool spindles, the B7018-C-T-P4S-UL stands out as a reliable industrial workhorse. Featuring a 15-degree contact angle (C-design) and a high-strength textile laminated phenolic resin cage (T-suffix), this angular contact ball bearing is specifically engineered to minimize heat generation during rapid rotation. Its P4S tolerance grade-which exceeds standard P4 precision-ensures exceptional running accuracy and minimal vibration, making it an essential component for high-end CNC milling and grinding centers where micron-level consistency is non-negotiable.

The "UL" designation of this FAG spindle bearing offers a significant advantage for maintenance teams: its universal design allows for flexible mounting in various arrangements, whether you need a back-to-back (DB) or face-to-face (DF) configuration with a light preload. With a standard 90x140x24mm footprint, it fits seamlessly into a wide range of industrial equipment. Designed for durability, the open structure facilitates efficient lubrication, allowing for limiting speeds up to 15,000 rpm under oil-air conditions. For engineers looking to balance high load-carrying capacity with extreme rigidity, this single-row bearing provides the precision and service life required for the most demanding manufacturing environments.
