BNK1202 Precision Ball Screw, 12mm Dia., 2mm Lead, with Standard Ends

As a Shaft-End Machined Type ball screw, the shaft ends are standardized for direct use with support units. This eliminates the need for secondary machining, saving significant time and cost.

Manufactured using a grinding process to achieve a C5 accuracy grade. The available preload option (G0 grade) minimizes axial play, ensuring high positioning accuracy and smooth, non-fluctuating operation.

Features a compact and low-profile nut and a relatively small shaft diameter, making it an ideal solution for equipment with strict space constraints.

Equipped with labyrinth seals (RR type) that effectively prevent dust and contaminants from entering the nut. The unit comes pre-lubricated with high-performance grease, reducing long-term maintenance needs.

As part of THK's standard series, this ball screw offers high dynamic and static load ratings, contributing to a long and dependable service life.
