Precision linear motion parts, specified before they are quoted

Nine component families, roughly 590 catalogue items at any one time: profile rail (MGN miniature, HGR heavy load, SBR round shaft) with matched carriages; ball screws from SFU1204 up to SFU3205 with BK/BF support blocks; trapezoidal and self-reversing lead screws from Tr8 to Tr40; KK and MKS single-axis modules; cross-roller and dovetail slide tables; shaft and bushing sets; rail clamps and clamping elements; and optical linear scales.

We are a trading company, not a factory. Parts come from a fixed set of Chinese manufacturers we have worked with for years, and we say which specification each part is built to. If a part has to be a specific brand, we will tell you whether we can supply it, rather than substitute quietly.

Every product page on this site states what is known and what is not. Where a supplier has not published a figure that decides the application — a screw lead, a rail preload, a clamp holding force — the page says so instead of filling the gap with an adjective.

Send the four or five numbers that define your axis: stroke, load, speed, required repeatability, and the mounting interface you have. With those the answer becomes a selection rather than a catalogue lookup, and the quotation is usually back within 24 hours.

We do not hold ISO 9001 or CE certification in our own name, and this site does not pretend otherwise. Several pages used to carry a certification line copied from a supplier listing; those lines have been removed and replaced with Confirm at RFQ.

What is available per order: dimensional inspection reports, material certificates from the mill, and a pre-shipment inspection video. Whether a certificate is required for your destination market, and whether the specific manufacturer holds it, is confirmed case by case before the order is placed.

EXW, FOB and CIF terms. Rails and screws are packed in cartons with plastic wrap and, for lengths above about a metre, in wooden cases. Custom lengths, end machining, and non-standard accuracy grades are quoted separately and usually add 3 to 7 days to the lead time.

Export experience covers North America, Europe, South America, the Middle East and East Asia. For destination-specific documentation requirements, ask before ordering — it is cheaper than finding out at the port.
