This rubber strip is used to secure Bivitec and Spaleck mats by knocking the strip between the profiles of two mats, thereby wedging the mats in place.
Used to prevent material leakage at the sides of the screen on Bivitec and Spaleck applications.
Polyurethane side bars come in various sizes, the most common size of side bar supplied by SCS is a 50mm wide and 60mm high bar, the length is varied to suit the screen length but normally a maximum of 1250mm long. There are twenty different width and height combinations of side bar that SCS supplies as standard and other can be made on request.
Side bars typically constructed from a steel plate or steel hollow section for strength and then polyurethane is moulded around all sides with attention paid to the thickness on the wear faces of bar.
Other more specialised side bars are available most commonly for the 85 system which have profiles moulded to them or are knocked into the 85 system girder are also available.

Polyurethane Wedges and metal cleats are used in conjunction with polyurethane or polyethylene side bars to clamp down screen media at each side of the screen.
Rubber centre hold down bars are predominately used for clamping down the centre of tensionable screen media such as rubber screen cloths or polyurethane screen mats. They are made from a steel backed rubber bar that is 50mm thick overall with a 42mm thick layer of rubber and 8mm thick mild steel plate, this centre hold down bars are 75mm wide and the length is usually equal to length of the mat or cloth they are clamping down. The centre bars are drilled with fixing holes as required and cored to ensure there is enough clearance to get a socket of the right size onto the fixing size specified.
These knockin bars fit into the 85 System girder and allow the fitment of 85 System polyurethane modules. The filler strips are for use at the side of the screen to fit the standardised modules to any size screen.
Polyurethane centre hold down bars are normally used in conjunction with the SCS plank system or polyurethane tensionable screen mats but are not limited to these two applications. Centre bars are essentially a bar which clamps something down most commonly in the centre of a screen. The SCS plank system has a centre bar with normally two or three holes in it that is used along with the pin and wedge clamping system to retain the centre of the module system, however this system can also be used on polyurethane tensionable mats or rubber screen cloths.
Another form of centre hold down is the bolt down version, which is when captive bolts are protruding up from the screen frame and the centre bar is used to bolt the screen media in place.
The SCS centre hold down is made from a steel channel section for strength and rigidity and then the wear resistant polyurethane is moulded around it to give the final product.

Our Slotted Pins, Metal Wedges and Polyurethane Protection caps work in unison to secure our centre hold down bars over the Plank Modular System. Simply secure the metal wedge through the slotted pin with a hammer to ensure your screen decks stay securely fastened down. A simple hammer strike in the ‘against-flow’ direction loosens the wedge so the centre bar can be removed, allowing two to four modules to be removed at once, allowing efficient maintenance and spacious access through to the deck below. As this wedge system requires a horizontal hammer strike, it is ideal to use in screens with limited space in lower decks, where swinging a hammer vertically is impractical or impossible.
Capping rubber is mostly commonly fitted on camber bars for support under tensionable screen media. Capping rubber is also known as bucker up bar rubber, nosing rubber and many other names. SCS stocks over 4000m of capping rubber in 20m rolls, it comes in three size type 0, 1 and 2. Type 0 has a 10mm lift (cap), Type 1 a 15mm lift and Type 2 a 20mm lift.
The 85 System girder is the basis of the 85 system and is welded or bolted down the length of the screen, usually at 300mm centres, to facilitate the fitting of 85 System screen media. This girder comes in 40mm high or 80mm high variants.
Dam bars are used to hold up material on the screen to prevent material carrying over and diverters are used to divert material while on the screen, for example, to more evenly spread the material in case of an uneven feed, or to avoid tracking of material if the screen has long blank areas.
Polyurethane dam bars come in two sizes for the SCS plank system the most common size of dam bar is 30mm high and the other is 75mm high. The dam bar is designed in such a way that it sits down in the modular system between two modules and is held in place by the side and centre bars.
SCS supplies side tensioning clamps for use with tensionable screen media such as woven wire, rubber screen cloths and polyurethane screen mats. SCS can supply side tension clamps to a standard or bespoke specific profile depending on the requirement. Most side tension clamps have square fixing holes punched in them for use with M16 or M20 screen bolts.
The side tension clamps can be supplied as plain metal, rubber covered or polyurethane covered, this is dependent on the application and customer preference.
There are many advantages to steel backed liners over more conventional sheet material linings. As the steel plate gives the liners rigidity it allows the lining to be made in smaller sections, which is advantageous regarding manual handling and the ability to change specific wear areas. Steel backed liners can be installed without specialist labour and when using a standard tile lining, spares are easy to stock and affect repairs as and when required.
Steel Backed Rubber Liners – Genuine steel backed rubber liners are constructed from a rubber that has been hot vulcanised to a steel plate. The rubber on these liners is a 60 shore hardness cut and wear resistant rubber. The liners come in two forms 300mm and 330mm square tiles, or bespoke liners that can be cut drilled to suit specific sizes from our stock 2m x 1m sheets. The sheeting comes in thicknesses of 15+3, 25+5 and 45+5mm thicknesses, the tiles are only supplied in the latter two thicknesses (The rubber thickness is the first number and steel thickness the second).
Thicker steel backed rubber liners can be made to special order, depending on quantity and lead time requirements.
Bonded Steel Backed Liners – These are liners that are made up of a piece of rubber bonded to a piece of steel using a cold bonding method. These are used when specific thicknesses of rubber or steel are required, or the size of the liners cannot be made from our steel backed rubber sheeting stock.
Steel Backed Polyurethane Liners – These are manufactured bespoke to each order so can be made to suit the customers specific requirements whether this be for square tiles or large sheets.
