PU Coated Roller with Built-In 686ZZ Bearings
This custom PU coated roller is designed as a non-powered idler roller for material feeding, guiding and pressure applications. It is fitted with two 686ZZ deep groove ball bearings and features a polyurethane outer surface for smooth, quiet and stable material handling.
The polyurethane coating provides good wear resistance, grip and surface protection. Compared with conventional metal rollers, the soft PU surface is suitable for handling paper, labels, films and other materials where scratching, marking or excessive contact pressure needs to be minimized.
The built-in double 686ZZ bearings provide smooth rotation and low rolling resistance, making the roller suitable for continuous operation in compact automation equipment and material transport systems.
Typical applications include label machines, packaging equipment, laminating machines, printing equipment, small conveyor systems and automatic feeding mechanisms. Depending on the machine design, the roller can be used as a feeding roller, pressure roller, guide roller or passive conveyor roller.
We manufacture PU coated rollers according to customer drawings, samples or specified dimensions. Roller diameter, overall length, shaft configuration and PU hardness can be customized. Available polyurethane hardness is typically Shore A 50A–90A, allowing the roller surface to be matched to different material handling requirements.

FAQ
Q1: What bearing is fitted inside this PU coated roller?
A: The roller is fitted with two 686ZZ deep groove ball bearings. The double-bearing configuration supports smooth rotation and stable running, making it suitable for continuous material feeding and guiding applications.
Q2: What material is used for the roller outer layer?
A: The outer layer is made of polyurethane (PU). Depending on the selected hardness, the PU coating can provide a combination of wear resistance, surface grip and low-noise operation. It is suitable for applications involving paper, labels, films and other materials that may be damaged by harder metal contact surfaces.
Q3: Is this a powered conveyor roller?
A: No. This product is a non-powered idler roller. It rotates through contact with the moving material or an external mechanism and is commonly used for feeding, guiding and pressure applications.
Q4: Where can this PU idler roller be used?
A: Common applications include label machines, packaging machinery, laminators, printing equipment, small conveyor systems and automatic feeding mechanisms. The exact roller design should be selected according to the material, contact pressure, speed and machine structure.
Q5: Can the PU coated roller be customized?
A: Yes. OEM and custom production are available. We can manufacture the roller according to customer drawings, samples or specified dimensions, including roller diameter, length, shaft configuration and other structural requirements.
Q6: What PU hardness options are available?
A: PU hardness can typically be customized from Shore A 50A to 90A. The appropriate hardness depends on the material being handled, required grip, contact pressure and operating conditions.
Q7: Can you supply the PU roller with bearings already installed?
A: Yes. The 686ZZ bearings can be pre-installed in the roller assembly according to the customer's requirements. This can simplify installation and reduce assembly work during equipment production.
