CERAMIC LAGGING

DESCRIPTION

Ceramic lagging can be specified when there’s a requirement for:

  • More grip than what rubber lagging provides.
  • Longer service life as a result of higher wear resistance than Rubber.
  • Grip increase (dimple tiles).
  • Increased resistance to wear/service life (smooth tiles).

The ceramic tiles provide optimum grip on pulleys subject to high stress. Aluminium oxide (Al2O3) ceramic material is suitable for pulley lagging, due to its specific properties of extremely high wear-resistance.

APPLICATION

Elastotec ceramic lagging is used in applications that require reliable operation and long service life. Benefits include reliable grip/traction under all conditions and longer service life than can be obtained with rubber lagging.

Ceramic lagging with rubber backing allows the ceramic tiles to move and adjust their position in response to the movement of the rubber belt cover. This helps protect the belt from wear and damage.

DESIGN

Elastotec ceramic lagging has vulcanised aluminium oxide tiles in rubber with rubber bonded to 5 surfaces of the tile to ensure tile cushioning and better adhesion strength. Tiles provide high abrasion resistance and rubber backing provides dynamic movement of the tiles.

Elastotec ceramic pulley lagging is made of a two different rubber layers co-moulded together. The top layer is a high abrasion resistant rubber formulated for 100% rubber tear bond to the ceramic tiles. The bottom layer is the CN bonding layer for increased adhesion. Elastotec’s specially formulated CN bonding layer is engineered to achieve ultimate adhesion when bonded to steel pulley surfaces. A buffed finish provides an increased surface contact and increases adhesion force.

Elastotec ceramic lagging is 250 mm wide to ensure easy handling and application. It can be supplied in thicknesses from 12mm to 25 mm. Thicker rubber allows more deflection of the tiles under the load. This reduces the risk of excessive wear of the bottom belt cover.

It can be supplied in three different forms:

1) In long roll lengths that fit on standard sized pallets to eliminate waste and for cost effective transportation and storage. Ceramic lagging in rolls can be cut to the pulley face width length to have a full face width ceramic coverage.

2) For hot vulcanised applications, ceramic lagging can be supplied in rolls together with rubber end pieces can be added to build your own strips.

3) Custom strips with vulcanised rubber ends to fit pulley face widths.

KEY FEATURES AND BENEFITS

95% Aluminium oxide tile material provides extreme wear resistance and resistance to cracking.
Rubber compounds designed to provide outstanding adhesion to ceramic tiles, rubber and metal.
Buffed CN bonding layer and buffed edges for optimum cold vulcanised adhesion to the pulley.
Dimensional physical properties stable with age.
Ceramic tiles bonded to rubber on 5 sides to resist tile cracking and pull out.
Tiles with raised dimples improve belt grip and tracking.
Smooth tiles to protect non drive pulleys from damaging the belt cover.
Can be hot vulcanised to the pulley to achieve best bonding to metal pulley shell.
Manageable size and weight. Supplied in strip form 250mm wide easy install.
Supplied in long rolls up to 50 m to reduce waste and be more cost effective and reduce stock requirement quantity as one roll fits all pulley widths.
Cutting sipes allow adjustment of strip width to suit pulley diameter.
Can be supplied in rolls or in strips with vulcanised ends for custom fit to pulley face width.
Elastotec guaranteeof no tile loss due to debonding.
