Reference: supplied catalogue pages 13–14. Values apply to the catalogue configuration and must be checked against the accepted order drawing. Maximum speed is not a guaranteed loaded machining speed. Angular figures are positioning specifications, not finished-part tolerances.
Standard and N Configuration
The catalogue groups standard and N variants in a shared specification column. N denotes the shortened motor-cover configuration. Check the exact variant drawing, motor/connector envelope and mounting dimensions; do not approve installation from table diameter alone.
Load and Installation Checks
Include the workpiece, chuck, fixture and attached components in the total load. Use the rating for your actual orientation. Confirm load offset, allowable moments, inertia, cutting forces and clamping requirements with the supplier before selection.
Check machine-table space, mounting interfaces, center height, tool access, tailstock alignment where applicable, and motor/cable clearance. Confirm the controller can support the intended rotary movement.
Information for a Useful Quotation
Preparing details with your engineer? Use the fillable technical inquiry worksheet, select MRNC-255 / 255N, save a PDF copy and email it with your drawings. You can mark missing details as unknown. For an existing machine, review the fourth-axis compatibility checklist before confirming the configuration.

- Installation drawing, quantity and delivery destination
We aim to provide an initial reply within 12 hours. Technical recommendations, price, availability and lead time are confirmed after reviewing the application and supplier information.
Dispatch & Limited Warranty
Dispatch within 10 working days after receipt of the agreed payment and confirmation of the technical configuration. Dispatch means shipment from origin; transit time, customs clearance and delivery to your site are additional.
One-year limited warranty from the dispatch date for confirmed manufacturing or material defects under normal use. The seller covers approved replacement parts and standard outbound freight for those parts. The buyer covers removal and installation labor, duties and taxes, and any expedited freight surcharge. On-site service or factory-return costs must be agreed in writing before work begins. Remote diagnosis is available without a service charge.
Procurement and After-Sales Support
Before ordering, use the pre-shipment inspection, packing and shipping checklist to agree the evidence, service scope, costs and timing required for your order.
Technical confirmation, inspection and packing/shipping coordination are available with the scope agreed in the quotation. The warranty starts on the dispatch date. The contracting seller and final order terms are confirmed before purchase. Read our procurement service and warranty overview.
