Linear Motion FAQs

Please provide the application type, stroke, payload, center of gravity, speed, acceleration, cycle time, mounting direction, required repeatability, working environment, available installation space and preferred motor brand. A simple layout drawing or photo of the machine is also helpful.

Ball screw modules are usually selected for higher positioning accuracy, higher thrust and short-to-medium stroke. Belt-driven modules are often considered for longer travel and faster transfer where screw-driven positioning performance is not the primary selection factor.

Rack and pinion modules are suitable for long-stroke, heavy-load and large-area handling applications. They are often considered when the travel length is too long for a ball screw or when higher rigidity is required over a long distance.

Linear motor modules are recommended for applications requiring high speed, high acceleration, smooth motion and fast response, such as precision inspection, semiconductor equipment, high-speed positioning and advanced automation systems.

A single-axis module provides motion in one direction. A multi-axis system combines modules into X-Y, X-Z, X-Y-Z, gantry, cantilever or other Cartesian structures for handling, dispensing, inspection, loading and assembly applications.

A gantry structure is preferred when the working area is wide, the payload is large, or the moving bridge needs support from both sides. It is commonly used for large-area handling, palletizing, inspection platforms, glass substrate processing and dispensing systems.

A cantilever structure is suitable for compact machines and light-to-medium payloads. It is commonly used in pick-and-place, screw tightening, dispensing, small-parts assembly and inspection stations where one-side support saves space.

Vertical-axis applications require a risk assessment. A motor brake and, where required, an additional anti-drop or mechanical safety measure should be selected according to payload, transmission, control strategy and applicable machine-safety requirements.

Pick-and-place automation usually uses single-axis, X-Z or X-Y-Z structures. For compact stations and small parts, ball screw modules provide stable repeatability. For long-distance transfer, belt-driven or rack and pinion modules may be more suitable.

Confirm the transfer distance, payload, speed, cycle time, acceleration, installation direction and whether the product is carried by a tray, fixture or gripper. For long stroke and high speed, belt-driven or rack and pinion modules are often considered first.

Machine tending commonly uses X-Y-Z or gantry systems around CNC machines and processing equipment. The selection should consider machine spacing, loading height, payload, reach, safety protection, gripper weight and cycle time.

Inspection and scanning require smooth motion, stable speed and repeatable positioning. Ball screw, belt-driven or linear motor modules can be selected according to camera weight, stroke, required speed and inspection accuracy.

Dispensing and coating require stable path control, smooth speed and repeatability. For precision dispensing, ball screw modules are often preferred. For large-area coating, synchronized dual X-axis gantry or belt-driven structures may be selected.

Screw tightening and small-parts assembly usually need accurate X-Y positioning and stable Z-axis motion. The Z-axis should be checked for thrust, rigidity, brake requirement and total tool weight including screwdriver, cylinder or suction cup.

Cleanroom compatibility must be reviewed by model and application. Please provide the required cleanliness class, materials, lubrication constraints, stroke, payload and speed so a suitable configuration can be evaluated.

Dustproof or covered modules are recommended for dusty environments. The final solution depends on dust type, installation direction, speed, maintenance conditions and whether extra covers, bellows or protective structures are required.

Yes. Many linear modules support standard stroke options and customized stroke evaluation. Please provide the required effective stroke, installation space and drawing constraints.

Motor positions such as inline, bottom-side parallel, right-side parallel and left-side parallel may be available depending on the product series. The motor position should be confirmed according to installation space and maintenance access.

In many cases, customer-provided motors can be supported. Please provide the motor brand, model, power, flange size, shaft diameter, brake information and encoder requirements so the adapter plate and coupling can be checked.

Yes. Origin sensors, limit sensors and different sensor layouts can be selected according to the control system. Please confirm whether NPN or PNP output is required.

Yes. CAD drawings and 3D models can be provided for installation checking and machine integration. Please confirm the selected model, stroke, motor position, sensor configuration and any special mounting requirements first.

Multi-axis configurations can be reviewed based on work area, payload, motion path, speed, accuracy and installation constraints. Available scope should be confirmed for each project before quotation.

Depending on the series and application, cover plates, bellows, adapter plates, special mounting holes or non-standard machining can be evaluated. Please provide drawings and working environment details.

Maximum speed depends on acceleration, deceleration, stroke length, payload and control settings. In short-stroke applications, the module may not have enough distance to accelerate to theoretical maximum speed before deceleration begins.

For long-stroke ball screw modules, screw critical speed and vibration can limit stable operation. When the stroke is long and speed is high, operating speed may need to be reduced to maintain stability and service life.

In horizontal installation, the module mainly supports the load weight and moment. In vertical installation, the drive system must also overcome gravity, so allowable payload, motor torque and brake requirements are different.

The center of gravity determines the moment applied to the slider and guide. If the load is far from the slider center, the actual moment may exceed the allowable value even when the weight is within the nominal load range.

Repeatability describes how consistently the slider returns to the same position under the same operating conditions. It is important for positioning, assembly, inspection, dispensing and other automation tasks.

Common causes include poor alignment, loose mounting screws, insufficient lubrication, excessive speed, overload, worn parts, long-stroke screw resonance or vibration from the machine frame.

Send the required stroke, payload, speed, mounting direction, repeatability, application description, quantity, motor requirement and sensor requirement. If drawings or photos are available, please attach them.

Price is affected by product series, stroke, drive type, load capacity, motor configuration, sensors, covers, precision grade, customization level and quantity.

Lead time depends on whether the model is standard or customized, stroke, motor and sensor configuration, production schedule, inspection requirements and shipping method.

Products are checked according to model configuration, dimensional requirements, assembly quality, motion performance and customer-specific requirements before delivery.

Linear modules are packed to protect the guide rail, screw, belt, slider, motor mounting side and external surfaces during transportation. Export-ready packing can be arranged according to the shipping method.

Please provide the original model, stroke, serial number if available, photos of the part and a description of the issue. This helps identify the correct replacement part and avoid mismatch.
