Product Description

KONWEYOUR® Supplied Conveyor Pulley Lagging Options
Looking for conveyor pulley lagging options for your pulley design?

All State Conveyors lagging specialists are able to fabricate reliable rubber and ceramic lagging to meet your pulley design needs.

We offer numerous rubber cover compounds and firmness options (durometers) to choose from, with Plain or Grooved Rubber Lagging and Rubber Backed Ceramic Tile Lagging options, utilising Full Sheet Wrap method or Replaceable Strip Lagging which is bonded to flat and crowned surfaces with cold bonding or autoclave hot vulcanising methods and equipment. Our fast turnaround services ensure quick delivery.

KONWEYOUR® Lagging, Delivers to Your Design Specifications
All State Conveyors are able to provide Drive Pulley (head) and Non Drive Pulley (tail, snub & take-up) lagging solutions for the use in all light to heavy-duty operations. Lagging can be directly bonded to customers steel work by using either cold bonding or hot vulcanising techniques with our in-house fully programmable autoclave. Drum lagging also assists the conveyor belt when it is has a tendency to aqua plane in wet weather or in adverse tracking situations.

All State Conveyors provide primarily 2 lagging options:
Plain Rubber and Grooved Rubber Lagging
Rubber Backed Ceramic Tile Lagging
Read below for the full details of our lagging options and recommendations for drive and non-drive pulley lagging.


Plain / Bare Lagging
Why Choose Plain Lagging? Plain lagging has a non-grooved flat surface, it is generally used on non-drive pulleys and is suitable for situations where water doesn't need to be removed as readily from the conveyor belt system such as snub and bend pulleys.

Rubber Type: Grade AS-M or similar

Rubber Hardness: 60 (± 5) duro Shore A

Suitable Pulley Type: Drive and Non Drive pulley such as Tail, Take-Up, Snub and bend pulleys

Pulley Size Capability: Applicable for standard sizes from 30mm~1500mm in diameter for hot vulcanising and the pulley size can be larger for cold vulcanising.

Durability: Low / Medium / High

Application / Bonding Process: Secured with cold adhesives or hot vulcanising

Stocked As: Standard Grade AS-M floor stock

Tips: When considering plain lagging, it is helpful to understand it is very similar to the Patten Grooved and can be used as is (without any groove style) but will not have all the other benefits. Plain and grooved lagging utilises the same bonding techniques.

All State Conveyors
Diamond Groove Lagging Profile
Why Choose a Diamond Groove Pattern? This grooved pattern is mostly used for reversing conveyor drive pulleys but can also be utilised for bi-direction circulation. Diamond grooved rubber lagging is ideal when more friction to the conveyor belt is required in wet or damp conditions. This profile pattern is excellent for water and dirt shedding.

Rubber type: Rubber: 60 Duro, Grade AS-M or similar

Rubber Hardness: 60 (± 5) duro Shore A

Suitable Pulley Type: Drive and Non Drive pulleys such as Tail Pulley, Take-Up Pulley, Snub Pulley and Bend Pulley

Size of Pulley: Applicable for standard sizes from 30mm~1500mm in diameter for hot vulcanising and the pulley size can be larger for cold vulcanising.

Durability: Low / Medium / High

Application / Bonding Process: Secured with cold adhesives or hot vulcanising

Stocked As: Standard Grade AS-M floor stock

Tips: Allowing a build up of debris in the grooves will greatly affect the friction between the pulley and the belt and cause the belt to eventually malfunction. This profile is a popular standard pattern for lagged conveyor pulleys at All State Conveyors and is readily available. Add image / Specifications

All State Conveyors
Chevron Lagging Profile
Why Choose a Chevron Pattern? This profile is designed for one directional drive pulleys and is also excellent at dispersing liquids and other sticky substances. It is more flexible when compared to the plain rubber option due to gaps in the rubber, which allows the lagging extra room to bend and move with the conveyor belt. The added flexibility also allows the rubber to keep in contact with the same section of conveyor belt and helps reduce overall belt slippage.

Rubber type: Rubber: 60 Duro, Grade AS-M or similar

Rubber Hardness: 60 (± 5) duro Shore A

Suitable Pulley Type: Drive and Non Drive pulley such as Tail Pulley, Take-Up Pulley, Snub Pulley and Bend Pulley

Size of Pulley: Applicable for standard sizes from 30mm~1500mm in diameter for hot vulcanising and the pulley size can be larger for cold vulcanising.

Durability: Low / Medium / High

Application / Bonding Process: Secured with cold adhesives or hot vulcanising

Stocked As: Standard Grade AS-M  floor stock

Tips: The points of the groove should meet in Chevron styled lagging. As the drive drum pulley is one directional, it is important that the lagging is bonded in the precise way by lagging specialists.

All State Conveyors
Herringbone Lagging Profile
Why Choose a Herringbone Pattern? The Herringbone lagging profile is designed for only forward action pulleys for the easy elimination of liquids and dirt from the pulley and the belt. It is more flexible when compared to the plain rubber option due to the gaps in the rubber, which allow the lagging extra room to bend and move with the conveyor belt. The added flexibility also allows the rubber to keep in contact with the same section of conveyor belt and helps reduce belt slippage.

Rubber Type: Rubber: 60 Duro, Grade AS-M or similar

Rubber Hardness: 60 (± 5) duro Shore A

Suitable Pulley Type: Drive and Non Drive pulley such as Tail Pulley, Take-Up Pulley, Snub Pulley and Bend Pulley

Size of Pulley: Applicable for standard sizes from 30mm~1500mm in diameter for hot vulcanising and the pulley size can be larger for cold vulcanising.

Durability: Low / Medium / High

Application / Bonding Process: Secured with cold adhesives or hot vulcanising

Stocked As: Standard Grade AS-M floor stock

Tips: It's important to understand that the Herringbone Lagging profile should have the grooves pointing in the direction of the rotation of the pulley. This action not only benefits the pulley but the supports the belt's forward action as well. This particular grooving is also designed to have exceptional traction.

Pulley Diameter (mm)	Number of rubber sheet	Number of retainers	Recommend Thickness of rubber sheet
φ500	10pcs	11pcs	12
φ630	13pcs	14pcs	12
φ800	16pcs	17pcs	12
φ1000	20pcs	21pcs	15
φ1250	25pcs	26pcs	15
φ1400	28pcs	29pcs	15
φ1600	32pcs	33pcs	20

Challenges with Ceramic Tiles Lagging
There are a few issues with ceramic lagging. Problems mainly arise when solid debris positions itself between the pulley and the belt, which may crack the surface of the tiles. This will result in weakening the ceramic, which may eventually chip, and free tiles from the pulley face surface. The dislodged damaged lagging will negatively impact the belt and drive functionality.

Rubber type: FRAS and M Grade uncured strip ceramic lagging

Profile Specialty: Hard wearing in abrasive conditions, assists with belt tracking and slippage, water shed Suitable

Pulley Type: Dimple ceramic lagging for Head or Drive Pulley, Smooth ceramic lagging for Non Drive pulley

Size of pulley: Applicable for standard sizes from 30mm~1500mm in diameter for hot vulcanising and the pulley size can be larger for cold vulcanising.

Durability: Low / Medium / High Application

Bonding Process: Secured with cold adhesives or hot vulcanising

Stocked as: Standard Grade AS-M floor stock

All State Conveyors
In circumstances where the belt might be isolated or housed independently for vertical applications, such as bucket elevators, the debris becomes abrasive and can cause constant abrasion to the belt and the pulley itself. This results in the tiles effectiveness being minimised and KONWEYOUR® would suggest seeking another lagging option as the wear rate will be too high. This is particularly so, for the recycling and primary manufacturing industries.

All State Conveyors offer customised ceramic surface lagging for your components. Based on your application, this treatment is used to increase or decrease friction and grip or increase wear resistance depending on your needs and budget.
