Conveyor pulley lagging

A high-quality Trellex Traclag pulley lagging system with a diamond-patterned tread is oart of Metso’s standard offering for OEMs.

Material properties

Made of wear-resistant Trellex T60 rubber, Trellex Traclag is can handle the internal wear that typically occurs between the points where the belt meets and leaves the pulley.

Special features

A contact layer of 0.8 mm enables good adherence to the pulley. It ensures a higher bonding strength without the need to buff the rubber, thereby minimising installation time.

Suitable for medium and heavy belt-tension applications, our diamond-profile rubber lagging delivers high durability and excellent resistance in outdoor environments.

Material properties

Rubber is a naturally flexible, elastic and abrasion-resistant material which enhances grip and reduces wear on the pulley shell. The particular rubber compounds used in our rubber lagging are formulated with advanced protection systems to resist outdoor environments and extend service life. Different rubbers are molded together. The top layer is engineered for maximum abrasion resistance in both wet and dry conditions. Beneath it lies an adhesion CN bonding layer, which is formulated to achieve the ultimate adhesion when bonded to steel pulley surfaces. The lagging nonetheless maintains a high level of flexibility, which enables it to shed carry-back and protect your conveyor belt.

Special features

A diamond surface profile helps remove dirt and water from the pulley. It also increases the coefficient of friction between the drive pulley and conveyor belt, increasing grip and improving the drive and tracking of the conveyor belt. Rubber lagging from Metso is available in both SBR Natural and FRAS approved compounds, each colour coded for easy identification. 

The product is delivered on easy-to-handle rolls that fit standard pallets.

A quality-engineered Trellex Griplag pulley lagging system has a surface pattern of conical rubber knobs. The simple fastening system enables replacing the pulley lagging without removing the belt or pulley – thus saving both time and money.

Trellex Griplag is not suitable for reversible belts.

Material properties

The design of the fastening system combined with the material’s surface pattern permit the rubber pulley lagging to stretch. This gives it a superior ability to handle internal wear.

The pattern also naturally eliminates water from the surface of the material as the pulley rotates.

Special features

The Trellex Griplag pulley lagging system was first invented by Metso almost 40 years ago and is still one of our best-selling products in this category.

Metso sets the standard and still offers the most reliable ways to handle internal wear and protect your belt.

Fastened to the pulley on just one side (no glue needed), the pulley lagging is designed to flap freely up and down as the pulley rotates, easily shaking off any dirt from the surface. It also helps that the rubber material is naturally flexible.

Trellex Pulley Bar pulley lagging with diamond surface pattern offer proven performance in heavy-duty applications.

Material properties

Made of hardwearing Trellex T60 moulded to an aluminium profile, this product has the perfect combination of elasticity and rigidity. Its elasticity enables it to handle the internal wear that typically occurs between the points where the belt meets and leaves the pulley. Its rigidity makes the product easy to work with. The surface pattern naturally eliminates water from the surface of the material as the pulley rotates.

Special features

A simple fastening system (no glue needed) makes it easy to replace the pulley lagging when necessary. This feature saves both time and money, since there is no need to remove the belt or the pulley. The Trellex Pulley Bar was first invented by Metso over 30 years ago. Metso sets the standard and still offers the most reliable ways to handle internal wear and protect your belt.

Suitable for use in the very worst weather or working conditions, the Trellex Cerlag is our top-of-the-line pulley lagging system. 

Material properties

Made of Trellex T60 combined with high-quality (92%) aluminium oxide ceramics, the product also has a contact layer for easy adherence to the pulley.

Aluminium oxide ceramic is an extremely hardwearing material, which helps to improve grip. However, if the inserts have sharp edges, they can cause damage to the belt. To avoid this, we have chosen to make our inserts circular, thereby eliminating sharp edges. So your belt is safe, and you still get all the benefits of the material’s excellent grip and performance.

Special features

Delivered on a roll, the rubber/ceramic material can be cut to fit your exact pulley length. This reduces waste, since there are no offcuts, and gives good availability since you only need to keep one item in stock.

If your application requires better grip or higher wear resistance than rubber can provide, our ceramic lagging is the answer. It brings you excellent reliability and a long service life, even when used with highly stressed pulleys.

Material properties

This product combines 95% aluminium oxide ceramic tiles with a rubber backing that cushions the tiles and increases adhesion. The tiles are highly resistant to abrasion and cracking, while the rubber backing enables them to move dynamically. The result is long-term dimensional stability which ensures reliability over a long service life. Performance can be fine-tuned by selecting dimple (more grip) or smooth (more wear resistance) tiles.

Special features

A specially formulated CN bonding layer is engineered to achieve ultimate adhesion when bonded to steel pulley surfaces. A buffed finish increases surface contact and adhesion force. We guarantee you will not experience tile loss due to debonding.

Our Metso ceramic lagging is available in two easily handled and economical formats: long length rolls to fit standard pallets and custom strips with rubber end pieces to fit your pulley face width.

Our polyurethane (PU) lagging extends the service life of non-drive pulleys. Its extreme abrasion resistance (better than rubber) and low friction coefficient makes it ideal for applications suffering premature wear, and situations in which damage to the belt cover must be avoided.

Material properties

PU resists the build-up of material, which makes this type of lagging particularly suitable for applications with carry back problems. It is also ideal whenever slippage between the conveyor belt and the lagging surface presents a problem, such as on-bend pulleys and non-drive pulleys on turn-over conveyors. Thanks to a low coefficient of friction, PU lagging is kind to belt covers.

Special features

The strips on our PU lagging are precision-moulded in an optimally formulated type of polyurethane PU. Highly abrasion-resistant PU inserts prevent wear on the pulley shell. Furthermore, the low coefficient of friction means PU lagging is kind to belt covers. PU lagging is supplied in easy-to-handle rolls that fit standard pallets. Plastic film packaging preserves the buffed bonding layer, ready for application.
