MCH09040H05K is an NSK Monocarrier MCH model (rigid type) all-in-one single-axis actuator: size MCH09, nominal stroke 400 mm, ball screw lead 5 mm (shaft dia. 15 mm), accuracy grade High grade (H), single slider (K). The unit integrates an NSK ball screw, linear guide and support bearing into one body, fully assembled, adjusted and lubricated at the factory (NSK K1 lubrication units built in) — just mount a motor and run. The MCH model uses a rigid rail cross-section suited to high-load, high-moment positioning; This grade offers repeatability ±0.010 mm with backlash of 0.020 mm or less. Basic load ratings: Ca 8,300 N / C0a 12,700 N (ball screw). The official NSK Monocarrier catalog PDF with dimension drawings is attached below.
Reference number breakdown: MC = Monocarrier, H = MCH rigid model, 09 = size, 040 = stroke code (×10 mm), H = accuracy grade, 05 = 5 mm lead, K = single slider — per NSK catalog CAT. No. E3162p "Reference Number Coding".

Sizing and integration support
Monocarrier eliminates separate sizing, assembly and alignment of ball screws and linear guides — with the factory motor bracket, simply bolt on a stepping or servo motor and run. Add your load, stroke, speed and accuracy requirements to the inquiry form; Nahshon works directly with NSK to confirm sizing, quotation and lead time.
