Epoxy repair compounds for worn shafts and journal bearings

Oscillating movements, lubricant loss, bearing failure or foreign matter contamination – typical causes for wear-and-tear on shafts, hydraulic pistons or rotationally-symmetric design elements.

Due to risk of distortion, conventional thermal and mechanical repair methods often cannot be used. Cost, availability, downtimes – all call for alternative technologies for component regeneration: Synthetic ceramic repair compounds - more information below:

Ask us about: undersized shafts, damaged journal bearings, fractured axle stubs, scored hydraulic rams, oversized keyways, loose shaft sleeves, worn ball joint housings

We have a solution for run in shafts / bearing journals! Scope of application: Undersized shafts Damaged bearing journals Fractured axle stubs Scored hydraulic rams Oversized keyways Loose shaft sleeves Worn ball joint housings MetaLine - Technical solutions in detail METALINE SERIES XL MetaLine Series XL are ceramic based repair materials for professional applications to damaged or dimensionally undersized components. The synthetic non-metal character enable the implementation of alternative repair processes. Bearing journals for example may be molded precisely to shape using a matrix process in installed condition - without mechanical machining. MetaLine Series XL products are particularly suitable for repairing shafts operated as a mating surface with sliding bearings or for use with gland seals or mechanical seals.
MetaLine Series XL are ceramic-based repair materials for professional use on damaged or no longer dimensionally stable components – a feasible, modern alternative method. Thus, for instance, bearing journals can be molded accurately when installed using a matrix process – without mechanical processing. The compounds are particularly suitable for repairing shafts operated as a mating surface with a plain bearing or in the gland and sealing area. MetaLine repair ceramics do not develop their strength through hardness, but through honing and lapping behaviour which polishes and levels the counter surface. The constructive wear potential is thus almost neutralized. At the same time, the XL series is more wear resistant than a typical metallic shaft material - but NOT harder!

Scope of application:

Undersized shafts
Damaged journal bearings
Fractured axle stubs
Scored hydraulic rams
Oversized keyways
Loose shaft sleeves
Worn ball joint housings

Technical solutions in detail

MetaLine Series XL –

MetaLine XL series are ceramic repair materials for the repair of shafts that have run in or are no longer dimensionally stable. They can be used to implement alternative processes: for example, bearing journals can be accurately molded in a matrix process - in the installed state.

The materials are particularly suitable for shaft repairs that are operated as a mating surface with a plain bearing or in the stuffing box and seal area. But only in layer thicknesses starting from 5/10 mm (20 mils) - below this, the load-bearing capacity is lacking. On the other hand, corrosion and fretting corrosion are a thing of the past, as there are no metallic ingredients contained.

MetaLine ceramic repair compounds do not develop their resistance through hardness, but through a honing and lapping behavior that polishes and smoothes the mating surface. This virtually neutralizes the constructive wear potential against the shaft itself. At the same time, the MetaLine Series XL is linearly more wear-resistant than a typical metallic shaft material - but NOT harder! Please watch the video on the right.

How long have we been doing this? Since April 1960! Any mores questions?

Wir lösen Erosionsprobleme an Ventilatoren / Gebläsen!
Synthetic repair processes are not yet omnipresent in mechanical engineering - but are being used more and more. What's wrong with the supplier who has the longest experience in this field? MetaLine - polymer solutions for metallic problems since 1960. No one has done more pioneering work . . .
Protective coating of a ship's shaft with our synthetic ceramic MetaLine KXL. Impressive and functionally a good solution - but physically the elastomers of our MetaLine Series 700 are even more impressive here - because we can additionally protect against impact and shock effects
Shaft repair - worn-in bearing area on this vacuum pump. A solvable problem if a professional preparation and a precise execution takes place. Unfortunately, this flaw is often attached to do-it-yourself procedures. MetaLine repair ceramics for such an application is neither quick nor easy - but functional!
Shaft coating - a new ceramic bearing area executed with the trowelable MetaLine repair ceramic SXL. The finishing is done with diamond tools. Why? What is supposed to be wear-resistant naturally also has a wearing effect on conventional tool steel. There is no better proof of the linear wear protection function of our process!
Shaft repair – this is a typical application for MetaLine Ceramic Repair compounds SXL. Electrically insulating and free of fretting corrosion
Shaft repair - here a partially worn-in shaft for reworking. Subsequently, a full-surface coating is applied to integrate additional corrosion protection
During coating with MetaLine repair ceramic KXL. A keyway seat repair can also be carried out in this process
Bearing journal repair - bearing journal coated with MetaLine repair ceramic KXL. Corrosion resistant and due to the electrically insulating properties an absolute protection against fretting corrosion
Shaft protection - bi-metal corrosion on this turbine drive shaft. Not an easy case and not an easy solution - despite MetaLine repair ceramics
Shaft repair – Self-extracting grit blasting of the repair surface with sharp-edged high-grade corundum (Al2O3). No other pretreatment is better suited to ensure sufficient adhesion for the expected load
Shaft repair coating – hydro-turbine shaft after the protection treatment with 1 mm of MetaLine KXL
Hydraulic ram repair – not an easy task but with the help of MetaLine SXL Repair Compound a real alternative to common chromium repairs
Bearing seat repair – trowelable MetaLine SXL has been successfully used to overhaule this damaged bearing area
Shaft coating – brushable MetaLine KXL protects this shaft from corrosion and chemical attack
Shaft protective coatings - it looks so simple, but without experience and routine such applications are very difficult. Ask us!
Shaft protection coatings - if nothing else works - then also in the installed condition. Polymer technology makes it possible!
