Stable conveying
Review elasticity and surface profile against contact position and load.
Polyurethane
sun wheels
For compliant board conveying, holding and guiding. Match the wheel profile and mounting details to the board and contact pressure.

PRODUCT OVERVIEW
Balance friction, elasticity and board protection
Sun wheels are used where corrugated board must be conveyed or held without unnecessary crushing. The wheel must provide useful friction while matching the machine interface.
01Custom diameter, bore, width and tooth profile
02Hardness and color reviewed for the application
03Confirm from drawing, photographs or current-wheel sample
04For conveying, hold-down and no-crush positions
Review around real machine data
Dimensional fit
Confirm diameter, bore, width, keyway and mounting method.
Sample matching
Use a complete sample when tooth geometry or legacy specifications are unclear.
Information to prepare before inquiry
| Dimensions | Outside diameter, bore, width and hub dimensions |
|---|---|
| Surface | Tooth, slot, circumferential profile or smooth design |
| Mounting | Keyway, fastening method, bushing or machine-specific connection |
| Material | Polyurethane hardness, elasticity, color and environment |
| Inquiry data | Machine position, current-wheel photographs, dimensions, quantity and problem |
Identify the machine position before selecting the wheel.
Working position
Sun wheels provide compliant conveying and guiding; lead edge wheels work in the feeder. Similar appearance does not make them interchangeable.
Mounting structure
Confirm bore, bearing, hub, holes, pins and contact profile. Use a physical sample for complex geometry.
Material and hardness
Review board type, contact pressure and operating conditions. Colour alone does not identify hardness or material specification.
Six checks before ordering a replacement
Outer diameter
Measure the maximum diameter and note whether the original wheel is visibly worn.
Bore and width
Record shaft or bearing dimensions, overall width and contact-face width.
Surface profile
Photograph teeth, slots, grooves and openings from the front, side and back.
Mounting details
Confirm hubs, hole counts and spacing; include drive-pin diameter, height and position where fitted.
Application and quantity
Provide machine model, position, board type, known hardness and required quantity.
Operating symptoms
For slipping, marks or skew, include speed, pressure, wear pattern and photographs of the installed set.
Frequently asked questions
Can you customize the profile, bore and hub?
Dimensions, contact profile, bearing or hub details can be reviewed from photographs, a drawing or a sample.
Is a softer wheel always better for reducing board marks?
No. Hardness, geometry, contact pressure, wear and diameter consistency across the set must be reviewed together.
Is a physical sample always required?
Clear measurements and photos may be enough for a simple structure. A sample is recommended for complex profiles or special mounting details.
Can I start with a trial order?
Trial suitability depends on dimensions, mold requirements and the production schedule.
