Coated Rollers: Product Introduction, Materials, Selection

Jan 03, 2024

Introduction to Coated Rollers

The rubber-coated roller is a transmission component in which elastomers such as polyurethane, silicone, and nitrile rubber are sintered and coated on the surface of the core material after a special sandblasting process. It can play a role in protection, shock absorption, and buffering. The coating thickness and hardness are optional, and you can also choose special product surface requirements, such as roller surface knurling, tapered rollers, or arc rollers, anti-static rollers, etc.

 

Commonly Used Materials for Coated Rollers

1.Polyurethane

It has good wear resistance. The higher the hardness, the greater the wear resistance coefficient. It is also oil-resistant, low-temperature resistant, aging-resistant, has high hardness, and is elastic. It is widely used to prevent scratches caused by tight transportation of fragile objects such as glass and acrylic. and cracks. Polyurethane has low dust resistance, and because it does not contain carbon, it is a material that is not prone to color transfer.

2. Silicone Rubber

It is a material with high heat resistance, good insulation performance and aging resistance. It is a highly safe product that can be used in medical, food, electronic equipment and other applications that require heat resistance. Rubber prevents scratches and cracks on the workpiece during fastening, it has a good effect in buffering and damping impact parts and preventing vibration.

3.Nitrile rubber

It is suitable for use in oil-resistant occasions, is relatively cheap, and is an economical product.

 

Performance of Encapsulated Materials

1. Hardness of the rubber coating material

At present, the hardness of the encapsulation material polyurethane, silicone rubber, and nitrile rubber ranges from A30 to A95.

Hardness Equivalent to
A95 Golf ball
A90 Baseball
A70 Softball
A50 Eraser
A30 Bicycle inner tube
