Choosing the Best Rubber Coated Roller: The Ultimate Guide

Choosing the Best Rubber Coated Roller: The Ultimate Guide

Introduction

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

?

1. Bearing type:

Suitable for linear conveying motion

(Polyurethane, nitrile rubber, silicone rubber materials can be selected)? ? ? ? ? ? ? ? ? ? ? ? ? ? ?

?

2. Grooved type:

Use with belt for clamping or sliding

(Trough size can be customized according to different belt sizes)


3. Piping type:

Different length options can be used in equipment for rolling or conveying.


4. Ring type:

Used with shafts for fixed rotation conveying


5. Type with set screw:

Use screws to fix on the shaft

Can be used for clamping, extruding or pasting

(optional high temperature resistant (120℃) polyurethane material)? ? ? ? ? ? ? ? ? ? ? ? ??

6. Threaded hole pattern:

It should be fixed on the shaft with screws and can be used for fixed rotation and transportation.


7. Type with keyway:

Use key slots or add screws to fix

Improve operational load-bearing and torque resistance capabilities

Suitable for high-load conveying, guiding, rolling, etc.

(Anti-static polyurethane material optional) ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??

Analysis of Materials and Characteristics of Rubber Coated Rollers

?

Polyurethane material:

1) Excellent wear resistance

2) Extremely high mechanical strength

3) Good surface self-lubrication

4) High elasticity coefficient

?

Silicone rubber material:

1) Excellent low temperature resistance (-70℃)

2) Excellent high temperature resistance (150℃)

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

choose:

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.
