- Hardness and tread profile selected to guide products with controlled contact pressure
- Bearing, hubbed, keyed and slip-on mounting configurations available
- Custom cores, inserts and finished assemblies produced to drawing or sample
No-crush wheels and rollers are also known as spacer wheels, zero-crush rollers and soft-touch wheels.
Shanghai Pepsen manufactures custom polyurethane no-crush wheels for corrugated, printing, packaging, bottling and material-handling equipment. Dimensions, hardness and mounting style are matched to the product, shaft and contact-pressure requirements.
Options include pre-installed bushings or bearings, hubbed or keyed cores, slip-on wheels and customer-specified core materials. Heat-resistant, antistatic and other application-specific polyurethane formulations are available after the service conditions are reviewed.
| Item | Available Options | Application Notes |
|---|---|---|
| Hardness | Shore 40A-95A; harder grades up to 80D by application | Selected to grip and guide without excessive compression or surface damage |
| Wheel core material | Aluminum, steel, stainless steel, nylon, acetal and other specified materials | Selected for speed, load, corrosion and weight requirements |
| No-crush wheel core or insert type | ||
| 1) Free-spinning with bearing | Low-friction rotation on a fixed shaft | Bearing installed to the specified fit |
| 2) Hubbed core | Hub and set-screw arrangement for shaft mounting | Bottling, labeling and spacing equipment |
| 3) Keyed core | Keyway transfers torque from the shaft | Indexing containers and driving or guiding products |
| 4) Slip-on without a rigid core | Flexible wheel installs directly on the specified shaft | Low-noise guiding and light-contact applications |
– Corrugated cardboard and textiles: The selected hardness and contact profile help reduce creasing, tearing and fiber damage.
– Printing operations: Guide paper, film and other substrates while limiting marking or distortion.
– Bottling and labeling: Space, index, feed and guide containers through automated equipment.
– Material handling: Move lightweight or delicate products with controlled contact pressure.
1) Bottle and material-spacing wheels
2) Feed rolls
3) Hold-down rolls
4) Transfer section rollers
– High-friction and abrasion-resistant formulations available for controlled feeding and guiding.
– Hardness and profile can be selected to help minimize pressure marks on corrugated sheet.
– In-house polyurethane processing and machining support custom cores, inserts and finished dimensions.
– FDA- and RoHS-compliant material options are available when specified and documented.
– Antistatic, flame-retardant and other performance options can be evaluated for the application.
Yes. We are manufacturer. Welcome to visit our factory.
Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
All of products with 3-6 months guarantee (except very frequently wearing parts).
We will response in 24 hours with solutions such as replacement or reworking.
We have dedicated personnel to sort out and maintain molds regularly.
20,000 times for compressions molds and 30,000 time for casting molds
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
