Choosing the Best Rubber Coated Roller: The Ultimate Guide

Jan 04, 2024


1. What is a rubber coated roller: A rubber-coated roller refers to a roller made of rubber material covering the core material. It is a common accessory in rolling transmission.


2. Why use rubberized rollers: Rubberized rollers have high hardness, excellent wear resistance, high elasticity even under high hardness, high surface finish, excellent grease resistance, and good chemical resistance. Can be used in harsh environments such as high and low temperatures, dryness and humidity.


3. The main function of the rubber-coated roller: it has high environmental adaptability.

(1) Improve transportation efficiency;

(2) Shock absorption and product protection;

(3) Reduce noise;

(4) Reduce oil pollution;

(5) High environmental adaptability


Types and Applications of Rubber Coated Rollers

3) Good weather resistance

4) Low wear resistance and mechanical strength


NBR material

1) Excellent grease resistance

2) Good wear resistance

3) Limited resistance to chemical corrosion, acid and alkali resistance

4) Poor temperature resistance (high temperature 80℃, low temperature -10℃)


Hypalon material

1) Excellent ozone resistance

2) High weather resistance

3) Better solvent resistance, acid and alkali resistance

4) Poor tear resistance and low mechanical strength


EPDM material

1) Extremely strong corrosion resistance

2) Extremely strong chemical resistance

3) Extremely weather resistant

4) Excellent hydrolysis resistance

5) Limited resistance to grease


Selection of Working Conditions for Rubber Coated Rollers


Working condition 1: High-strength and high-wear working conditions

Choice: High wear-resistant A90-degree or 95-degree polyurethane (PU) rollers.


Working condition 2: Harsh high or low temperature working conditions

Choice: silicone rubber (SI) roller (can be used in -70℃~150℃).


Working condition 3: Working conditions with both temperature requirements and wear resistance

Choose: Heat-resistant polyurethane (PU) roller (can be used in -20℃~120℃).


Working condition 4: Corrosive working conditions

Choice: EPDM roller.


Working condition 5: Humid and long-term contact with water

Choice: EPDM roller.


Working condition 6: Anti-static working condition requirements


①〈Both anti-static properties and wear resistance are required〉Choose anti-static polyurethane (PU) rollers;

②〈Permanent anti-static performance〉Choose anti-static rollers made of silicone or rubber.


Working condition 7: Acidic, alkaline and ozone working conditions

Choose: Hypalon Roller.
