THK Spinning Ball Nut – BLR2525-3.6UU (25/25 Standard Type)

The THK BLR2525-3.6UU Spinning Ball Nut is a premium-grade linear motion component designed for precision applications requiring accuracy, rigidity, and durability. Engineered for 25mm ball screws with a 25mm lead, this nut provides efficient load distribution through its internal recirculating ball mechanism. The double-sealed (UU) design prevents contamination while maintaining consistent lubrication during operation. Constructed from hardened steel and ground to tight tolerances, the BLR2525-3.6UU delivers quiet, low-friction performance under continuous-duty conditions. Ideal for CNC routers, industrial automation, and high-speed positioning systems where precision and longevity are critical.
