SKF 7226 BECBP4 Angular Contact Ball Bearing Z13

SKF 7226 BECBP4 Angular Contact Ball Bearing Z13 is a high-precision, single-row angular contact bearing from SKF designed for demanding spindle and machine-tool applications. The bearing size is 130 mm bore, 230 mm outer diameter, and 40 mm width, placing it in the common 130×230×40 mm class used for precision spindles and CNC equipment. It carries a P4-class tolerance designation, reflecting tight runout and dimensional control suitable for high-speed, preload-sensitive setups. The Z13 suffix indicates a shielded variant within the 7226 family, offering protection against contaminants while enabling reliable operation in cleanroom or workshop environments with reduced need for frequent re-lubrication under steady conditions. This bearing is well suited for CNC spindles, milling and grinding machines, and other high-precision tooling where accurate axial support under combined radial and axial loads is essential. In practice, engineers select the 7226 BECBP4 for applications requiring stiff preload response, repeatable positioning, and long-term reliability in spindle and precision-motion tasks, leveraging SKF’s precision raceways and ball geometry within the 7200-series family. The compact 130×230×40 mm footprint and high-precision design help simplify mounting in standard angular-contact configurations, while the P4-grade accuracy supports tight tolerances and consistent performance across thermal cycles and load conditions.
