Adhesive blocks A simple but effective way to reduce wear, is to use „metal-protection blocks“ for surface conditioning. The blocks are mounted in a way, that they continuously glide on the surface, which should be protected, using spring pressure (like electric carbon brushes). In that way, a protective layer of 0.001 - 0.005 mm is applied. The particles are integrated into the metal or plastic surface where they produce a highly stressable dry layer. The adhesive blocks with a friction coefficient of 0.3-0.7 are used to protect against wear but at the same time keep the necessary friction (driving...

Lubrication blocks Lubrication blocks with a friction coefficient of 0.015 are used to protect against wear and at the same time lubricate dry, continuously and maintenance-free. Characteristics: dry und dust repellent - used in harsh operating conditions and dusty environments where oil and grease can't be used because they are dust binding for high tangential speeds - e.g. on turning parts. High centrifugal forces are responsible for high losses of oil and grease lubrication. Our lubrication blocks are the perfect solution. high-temperature resistant low-maintenance - only small amounts of wear...

MOLYTROP® - Dry-Lubricant „fluid„ MOLYTROP® is made of MoS2 with organic and inorganic components, which control the stability and flow characteristics. The substrate transports MoS2 components to the dedicated lubrication point. By the movement of the friction partners the MoS2 is rolled into the surface and completely dries. In that way a highly stressable, wear-resistant and dry lubrication layer of MoS2 is produced. MOLYTROP® often replaces loss lubrication through oil and grease by working on minimum lubrication. MOLYTROP® does not contain any mineral oil! MOLYTROP® is filled in commercial...

Bonded coating A monoconstituent lacquer for tribological surface coatings. It consists of a fast-drying lacquer and a carefully emulsified high-purity-electrographite (HG045). Characteristics: Surface: dark grey Densitiy: ca. 1.05 g/cm3 Drying process: depending on the layer thickness dry to touch after 3 h, completely dry after 24 h at 20 °C, 60% relative humidity. Spreading capacity: 1 l depending on the application type and layer thickness, 1 l is enough for 8-10 m2 per coating Storage: store frost-proof; in closed containers for max. 6 months. All surfaces have to be free of rust, contamination,...

Application in asphalt mixing plants Chain drive: The drum dryer is driven by a chain. Problem: Lubrication of supporting rolls and rings by oil and grease is required. manual lubrication is complex environmental factors: dust, rain, pollution,... environmental pollution from dropping lubricant costs for new rolls are about € 14,000.Solution: According to the width of the rollers, two sets of dry lubrication blocks (HG020) are mounted on the supporting rollers. Drum dryer - chain drive Thanks to the dry lubrication blocks a maintenance-low, ecological, dry and water resistant lubrication is realized...

Application on containers and outdoor cranes Large cranes consist of certain parts: ground tracks, crane base carriages, main structure, horizontal beam or cantilever and one or multiple trolleys. Longer manipulation distances are executed by the crane base carriage, load manipulation is executed by the trolley. The crane base carriage and the trolley are partly equipped with flange wheels or/and supporting rollers. Those run on trails wich are driven by electric motors. Because of large charges at the contact point between wheel and trail, a lot of friction and wear occur in this applications....

Applications on Indoor cranes Indoor cranes usually consist of chassis rails and crane trolleys. Long distances are executed by the chassis rail, load manipulations with the trolley. The trolley drive is generally made for faster movements than the chassis rail drive. Chassis and trolley are equipped with flange wheels and/or supporting rollers. They are driven by electric motors, the wheels are exposed to large loads due to friction wear on the wheel-rail contact point. Problem for treads: High wear on treads or rail heads of wheels and rails. Friction loss through strain hardening or flaking...

Application on rotary kilns In rotary kilns materials are heated and/or mixed, burned or sintered by rotation. Those installations are driven by sprockets or chain drives. The load of the drum is carried by the supporting rollers. The axial rollers stabilize and move the rotary kilns. Axial rollers (thrust rollers) are hydraulically or mechanically pressed to the ring flanks. Industries: Cement-, lime-, gypsum plants, plaster and mortar industry, chemical factories, paper mills, steel plants, sugar factories, quarries, raw material industry, etc. Problem on supporting rollers: Manual lubrication...

Wear protection on high-bay warehouses Application bottom rail storage and retrieval machine: Blocks and mountings: standard mounting types 0030 and adhesion blocks type 10035 for wear protection of rail and adjustement of the optimum friction coefficien (dry 0.7 and wet 0.35) on drive wheels. Wear protection and dry lubrication through lubrication blocks 10036 or HG045 on lateral supporting rollers. Various dimensions are possible! In case of highly stressed lateral drive wheels, we suggest using lubrication blocks type 10036 – they contain more than 40% of MoS2 and generate a heavy-duty wear...
