Description Solid lubricant sliding strips or sliding plates

Solid lubricant sliding strips or sliding plates

The LUMET solid lubricant sliding strips and sliding plates are made of solid bronze with a permanently integrated graphite lubricant. The load limit of these solid lubricant sliding strips is therefore considerably higher than that of standard sliding strips, which are lubricated by an oil film.

LUMET solid lubricant sliding strips or sliding plates are used for heavy loads, in anti-corrosion applications or when the lubricant is very difficult to introduce. This doubles the performance characteristics in terms of hardness and wear resistance.

Sliding strips and sliding plates from the LUMET series are used in particular in the offshore sector and in connection with food or textile machinery.

Solid lubricant sliding plate LUMET-GL

LUMET is a solid bronze slide plate with integrated graphite lubricant that enables automatic and energy-efficient lubrication and offers significantly higher load limits than oil-regulated elements. It is suitable for heavy-duty operation and corrosive environments as well as hard-to-reach lubrication points, for example in die casting, mining, shipbuilding, turbo generators and injection moulding machines.

Solid lubricant sliding plate LUMET-GLSH1

LUMET-GLSH1 is based on the CuSn5Pb5Zn5 alloy and combines good wear resistance with reliable emergency running properties and high corrosion resistance. The material of the slide plate is suitable for medium loads up to 400 °C and enables dry sliding operation up to approx. 10 m/min.

Solid lubricant sliding plate LUMET-GLSH2

Made from CuAl10Ni5Fe5 aluminium bronze, the LUMET-GLSH2 solid lubricant slide plate offers high strength, outstanding fatigue resistance and very good chemical resistance. The alloy of this sliding strip is a versatile all-rounder for high loads up to 400 °C and sliding speeds up to approx. 20 m/min.

Solid lubricant sliding plate LUMET-GLSH3

Based on the high-alloy tin bronze CuSn12, the LUMET-GLSH3 solid lubricant slide plate offers good toughness, high wear resistance and reliable emergency running properties even with limited lubrication. The alloy of this sliding strip or sliding plate is suitable for alternating loads up to 400 °C and sliding speeds up to approx. 10 m/min.

Solid lubricant sliding plate LUMET-GLSH5

Made from CuZn25Al5Mn4Fe3 aluminium-manganese bronze, LUMET-GLSH5 offers very high strength, hardness and outstanding corrosion resistance. The material can withstand temperatures of up to +150 °C and speeds of around 15 m/min and is particularly suitable for high point loads at moderate speeds.

Solid lubricant sliding plate LUMET-GLHHP

Made from CuZn25Al5Mn4Fe3 aluminium-manganese bronze, LUMET-GLSH5 offers very high strength, hardness and outstanding corrosion resistance. The material can be used at temperatures up to +150 °C and speeds of around 15 m/min, and is particularly suitable for high point loads with a moderate speed profile.

Material structure

The material of the LUMET sliding strips and sliding plates is characterised by high strength and excellent load-bearing capacity - even under alternating or shock loads. The embedded solid lubricants form a uniform friction film on the bearing surface during commissioning and transfer this to the mating material on first contact.

This is particularly important under dry running conditions:
A running-in film is formed at the beginning, which smoothes the friction partners and transfers the solid lubricant specifically into the microstructure of the mating surface. This reduces stick-slip effects, micro-vibrations and plastic deformation - the typical causes of friction and wear in unlubricated metal pairings.

In contrast to conventional lubricants, which are displaced from the contact area under pressure, the solid lubricant film in LUMET sliding strips and sliding plates remains stable in the friction zone. The lubricant is continuously released from the plugs and evenly distributed due to the micro-movements during operation.

The result:

• Constantly low frictional resistance
• Minimised wear even under high loads
• and a significantly longer service life of the bearing point

Material properties

LUMET materials have been developed for demanding applications and impress with the following properties:

• Maintenance-free operation with a long service life
• High load capacity - under both static and dynamic loads
• Constantly low coefficient of friction - without stick-slip effects, even in start-stop operation
• Resistant to dirt, corrosion, impacts and edge loads
• The cast copper alloy has a shock-absorbing effect and protects neighbouring components
• Generous temperature range - for applications in extremely cold or hot environments.
• Suitable for linear, rotating and oscillating movements
• Long service life and service life
