Frequently Asked Questions About Custom Rubber Rollers

A complete roller drawing is the best starting point.

If a complete drawing is not available, please provide the main roller dimensions and requirements, including the roller diameter, rubber face length, total length, shaft dimensions, mounting positions, rubber cover thickness, quantity, and any surface or accuracy requirements.

If possible, please also provide clear photos or videos of the complete roller and its position on the machine. Please explain the roller function, the material or medium contacting the roller, working temperature, speed, pressure, cleaning method, and any current production problem.

This additional information helps us understand the actual working conditions and further confirm a more suitable material, hardness, surface and manufacturing specification.

Yes. Wolorin manufactures complete new rubber rollers and also provides rubber re-covering and refurbishment for suitable existing roller cores.

If an existing roller core is seriously deformed, corroded or structurally damaged, a new roller core or complete roller replacement may be required.

Yes. Single replacement rollers and small custom batches are both common orders.

A single roller is often used for equipment replacement, trial use or an initial project. Once the first roller has been put into operation successfully, subsequent orders for the same roller position can usually be handled more efficiently.

As we become more familiar with your processed materials, production line and actual working conditions, it also becomes easier to discuss rollers for other positions or additional production lines.

When possible, please provide clear photos or videos showing the roller position and the surrounding working area.

Please explain the material contacting the roller, the function of the roller at that position, and whether it is exposed to oil, solvents, adhesives, ink, acids, alkalis or other media.

Working temperature, line speed, pressure, cleaning method, traction or release requirements, and the previous roller’s failure condition are also important.

The rubber material and hardness should be selected according to the actual working conditions.

Yes. Rubber hardness, cover thickness and surface condition can be customized according to the roller function and working conditions.

Available surface options include smooth, precision-ground, matte, specified roughness, traction-oriented, release-oriented and anti-sticking finishes. Straight, spiral, diamond and other groove patterns can also be produced.

Crowned profiles can be used when compensation is required because of the roller structure or pressure distribution. The final specification should match the processed material, roller position, speed, pressure and required production result.

Wolorin supports a wide range of custom industrial rubber roller sizes, compounds and structures.

Typical manufacturing capability includes:

• Roller diameter up to approximately 1,500 mm
• Rubber face length up to approximately 12,000 mm
• Rubber hardness typically from 20 to 95 Shore A
• Steel, stainless steel, aluminum or carbon fiber roller cores
• Custom shafts, flanges and internal structures

Available rubber compounds include polyurethane, silicone, EPDM, NBR, FKM, CSM, neoprene, natural rubber, SBR, butyl rubber, and anti-static or conductive compounds.

In addition to common industrial rubber compounds, we have a broad range of modified and application-specific formulations for requirements involving wear, traction, release, temperature, oil, solvents, chemical media, static control and sensitive surface contact.

These compound options can cover most common industrial working conditions, as well as many demanding or specialized applications.

Yes. The material, hardness, surface and structural details of a new or refurbished roller can be adjusted according to the actual problem.

Please describe the problem clearly and explain the roller position, processed material, operating speed, temperature, pressure, contact medium and cleaning method. It is also helpful to explain how long the roller has been used and whether the problem changes after cleaning, grinding or replacing the roller.

Common roller-related factors include material mismatch, unsuitable hardness, surface condition, contamination, wear, swelling, cracking, uneven contact and bonding failure.

The price depends on the roller diameter, length, total weight, rubber compound, hardness, cover thickness and quantity.

The roller core and shaft structure, surface finishing, grooves, crown, dimensional tolerance, runout and dynamic balancing requirements can also affect the price. New roller manufacturing and rubber re-covering use different materials and production processes, so their pricing will also differ.

A drawing or complete dimensional information is normally required for an accurate quotation.

Most custom rubber rollers are completed within approximately 1–3 weeks after the specifications and order details are confirmed.

The actual delivery time mainly depends on the roller size, material, structure, quantity and processing requirements. The expected delivery date will be stated when the order is confirmed.

Rubber rollers are inspected according to the drawing and confirmed order requirements. Inspection may include the main dimensions, rubber hardness, cover thickness, surface condition, shaft and mounting dimensions, as well as runout and dynamic balancing when required.

Before shipment, the rubber surface, roller ends and shafts are protected to reduce the risk of damage during handling and transportation. Packing is selected according to the roller size, weight, destination and shipping method, including suitable export wooden cases when required.

Inspection photos or relevant records can be provided according to the order requirements.
