Wear Protection for Plant and Machine Engineering
In plant and machine engineering, bearing seats, shafts, guides and tools operate under continuous load. Friction, pressure, foreign matter and alternating stress remove material and widen tight fits.
A worn bearing seat, a damaged shaft seat or a worn gear can, in the worst case, bring the entire machine to a standstill. A new part is often expensive and may take weeks to deliver.
We supply wear protection solutions, spare parts and welding consumables that address exactly these issues and keep your components in service longer.
Typical Welding Defects on Machine Components
When restoring shafts, gears and housing parts, heat management determines subsequent dimensional accuracy. Two defect patterns occur particularly frequently — both can be reliably avoided with the right approach.
Problem: Distortion Due to Uneven Heat Input
If heat is introduced unevenly during welding, the component distorts. On shafts, guides and housing parts, tight tolerances are lost and the function is no longer correct.
Our Solution: Controlled Heat Management
With preheating, a matched layer sequence and slow cooling, we keep thermal stresses low. The component remains dimensionally accurate and requires only minimal reworking.
Problem: Cracking Due to Incorrect Alloy or Cooling
An unsuitable alloy, too-rapid cooling or missing heat management leads to cracks in the weld. For dynamically loaded components such as gears and couplings, this quickly becomes a failure risk.
Our Solution: Suitable Welding Consumable and Heat Management
We select the welding consumable to match the base material and load, and manage the heat in a controlled manner. The result is a crack-free, permanently load-bearing joint.
Suitable Welding Consumables for Bearing Seats, Shafts and Tools
In machine engineering, every load is different: friction wear on sliding surfaces, fit wear on bearing seats, alternating loads on gears and couplings. We select the filler material application-specifically according to base material and function. For sliding surfaces, slideable alloys are used; at bearing seats, dimensionally stable materials; for impact and alternating loads, tough, impact-resistant alloys. This matches the applied layer to the specific task of the component. Via the following wear types you can reach the appropriate welding consumables for each application area.

In plant and machine engineering, components such as bearing seats, shafts and housing parts, guides and linear guides, gears, couplings and plain bearings, or tools such as dies, punches and clamping jaws are subject to particularly heavy wear. We protect them with hard overlay and restore them. Here you will find suitable wear and spare parts for your equipment:
Fully Automated Overlay Welding and Additive Manufacturing
In the Laser Competence Centre, capilla brings together modern technologies for coating and component manufacturing.
Here, components are specifically treated, wear-resistant layers are applied and complex components are manufactured using additive processes such as 3D cladding.
This enables solutions that go beyond conventional welding applications and make components sustainably more capable.

capilla Wear Protection to Bulk Material Specification
We do not work with standard recipes. Whether bulk material, medium or workpiece — what matters is always the actual load acting on the component. Grain size, hardness, temperature, flow or chemical aggressiveness determine which type of wear dominates and which protection truly fits.
Before we define the welding consumable, process and layer structure, we analyse the operating conditions. This results in a solution tailored to your component. Tested consumables and defined parameters are part of this — supplemented by standards-compliant documentation for safety-critical components.
Frequently Asked Questions about Wear Protection in Plant and Machine Engineering
The greatest wear in machine engineering occurs at bearing seats, housing parts, guides and tools. These are the machine components exposed to permanent mechanical load during operation. Point loads at bearing seats, friction wear on guides and fit wear on shaft seats limit machine service life over long operating periods.
The most common causes are foreign matter, friction, pressure and abrasion. Added to this are shear forces and alternating loads on shafts, gears and couplings, as well as fit wear at bearing seats, where repeated material removal widens the originally tight fits. Which cause dominates depends on the machine type and the specific application.
Repair welding is particularly worthwhile in machine engineering for large, expensive or delivery-critical components such as shafts, housing parts, gears and special tools. As a rule, restoration with targeted overlay welding is significantly cheaper than a new part and usually available within a few days, while special-order parts can take weeks or months.
In machine engineering, application-specific alloys are used, matched to the base material, type of load and function of the component. For friction wear on sliding surfaces, slideable alloys are used; for fit wear on bearing seats, alloys with high dimensional stability; for alternating loads on gears and couplings, tough materials with sufficient impact resistance.
Decisive are clean preparation of the weld zone and the correct welding parameters. Added to this are the right material selection and a matched layer build-up. In machine restoration, this combination of preparation, parameters and material ensures the subsequent dimensional accuracy and function of machine components.
The typical defects when welding machine components are distortion and cracking. Distortion arises from uneven heat input, cracking from unsuitable alloys, too-rapid cooling or missing heat management. Both defects reduce dimensional accuracy and service life of the component and must be actively prevented.
Distortion and cracking are avoided through controlled heat management and the use of the correct welding consumable. Preheating, a matched layer sequence and slow cooling reduce thermal stresses. For large shafts, gears and housing parts, heat management determines subsequent dimensional accuracy and function.
Machine service life increases through targeted reinforcement of stressed areas. At bearing seats, shaft seats, guides and tools, the wear-prone zone is equipped with application-specific overlay layers instead of hardening the entire component. This preserves dimensions and fits for longer, and machine components need to be replaced less frequently.
Precision plays a central role in machine restoration because bearing seats, shafts, guides and mating surfaces must be restored to the tightest tolerances. High demands on dimensional accuracy apply especially to components with point loads or dynamic alternating loads, where even the smallest deviations impair function and service life.
Dimensional accuracy is achieved through experience and process control — specifically through sufficient welding allowance, controlled heat management, matched layer build-up and subsequent mechanical reworking. This allows shafts, bearing seats and tools to be brought back to their original nominal dimension with reproducible accuracy.
Almost all heavily stressed machine components can be restored by overlay welding: bearing seats, shafts, housing parts, guides and linear guides, gears and couplings, plain bearings and slide blocks. Also tools such as dies, punches and clamping jaws, as well as process plant components such as auger flights and agitator blades.
