URS220 Series CNC Hardened Guideway Slide Table

URS220 CNC Hard-Rail Slide Table

URS220 is part of the JNYO single-axis hard-rail slide-table range. Compare the configurations below when preparing a machine feed or positioning module. Application suitability depends on workpiece and fixture mass, cutting force, overturning moment, feed motion and the mounting arrangement.

Catalog configurations

Source: JNYO product catalog, printed page 76 (PDF page 41), Chinese edition, approximately 74 MB. The stroke column does not print a separate unit; values are reproduced as shown. Confirm units and complete dimensions on the configuration drawing.

The same catalog model can have different table dimensions and travel. Match the complete configuration to the drawing. Weight below is slide-table reference weight, not permitted payload or cutting-load capacity.

Drive and installation references

The matching model table lists ball screw Φ25×6 and shaft diameter Φ17. These are catalog notation references; confirm units, tolerances, support arrangement, motor interface and mounting dimensions on the selected drawing. Guideway covers and servo motors can be configured according to requirements.

Hard-rail series construction

The catalog series description, printed page 75 describes T-shaped rectangular hard guideways, heat treatment with surface hardness of at least HRC50, a cast-iron housing with vibration and natural aging, fitted and hand-scraped contact surfaces, and an internal oil-distribution system. These are published series descriptions, not an inspection certificate for an individual assembly.

The source does not assign HT250 or HT300 grades to this model, or establish one positioning-accuracy, load-capacity or duty-cycle rating for every configuration. Specify material grades, screw accuracy, lubrication, protection and acceptance conditions in the technical agreement.

Selection information to provide

• Required effective travel, feed direction, mounting orientation, interface drawing and available space.
• Workpiece and fixture mass, center of gravity, cutting forces and overturning moments.
• Feed speed, acceleration, operating frequency and continuous-duty requirements.
• Positioning and repeatability targets, test method, motor and control interfaces, lubrication and protection environment.
• Associated machining units, quantity and requested delivery date.

Configuration questions

Can weight be used to select a heavy-cutting application?

No. Weight is not a load rating. Review the force direction, center of gravity, drive, mounting and cutting cycle for the complete machine.

Does the model name identify an interchangeable assembly?

No. The catalog contains repeated model designations with different table dimensions and travel. Confirm the full dimensional drawing and interfaces before replacing or ordering an assembly.

Request the matching dimensional drawing and compatible 3D reference before manufacturing the machine interface. Availability, quotation, delivery time and installation or after-sales support must be confirmed for the order.
