Roller bearings

MOVEMENT PROGRESS TECHNOLOGY

Rolling bearings and track rollers engineered for demanding applications

When standard bearings reach their limits, KÜPPER develops the bearing solution that fits your application: precise, durable and designed to reduce downtime, simplify assembly and improve process reliability.

Artur Küpper GmbH & Co. KG has been developing and manufacturing high-quality rolling bearings, track rollers, special bearings and complete bearing assemblies in Velbert, Germany, since 1933. We combine application engineering, in-house production, short decision-making paths and German manufacturing quality for industrial customers worldwide.

• Custom rolling bearings designed around load, speed, temperature, media, lubrication and installation space
• Track rollers and special rollers with application-specific profiles, sealing systems, greases and materials
• Bearing assemblies with integrated shafts, bolts, flanges, lubrication features, gears or special geometries

From the raw part to the finished bearing assembly: the film shows how KÜPPER combines engineering, precision machining, defined greasing, assembly and quality inspection in one coordinated process.

Custom rolling bearings when standard solutions are not enough

In demanding machinery, bearing life is rarely determined by dynamic load rating alone. Temperature, cleaning media, humidity, dust, corrosion, lubrication ageing, installation tolerances, profile geometry and limited installation space often decide whether a bearing runs reliably or fails too early.

KÜPPER looks at the complete application. Based on your operating conditions, we develop a technically sound and economically sensible solution: from modified standard bearings and custom track rollers to fully integrated bearing assemblies ready for installation.

Bearing types

• single-row and double-row ball bearings
• deep groove ball bearings
• angular contact ball bearings
• four-point contact bearings
• roller bearings and needle bearings
• hybrid bearings and stainless-steel bearing solutions
• high-temperature bearings and low-maintenance bearing concepts

Track rollers and assemblies

• track rollers, support rollers and cam followers
• profile track rollers and flanged rollers
• rollers with plastic outer jacket
• ready-to-install bearing assemblies
• special bearing units with shafts, bolts, flanges or lubrication systems
• application-specific profile geometries and sealing packages
• special greasing, defined filling quantities and adapted lubricants

High-temperature bearings

Heat influences lubricant behaviour, material properties, internal clearance and sealing performance. KÜPPER develops high-temperature bearing solutions for ovens, dryers, coating lines, baking technology, hot conveyors and other thermally demanding applications.

• Design focus: temperature range, internal clearance, material selection, cage design, seal type and lubricant.
• Options: stainless steel, hybrid bearings, special cages, high-temperature greases or solid lubrication concepts.
• Result: reliable bearing operation under thermal stress and reduced maintenance risk.

Rolling bearings and track rollers with CorrPrevent®

Moisture, condensation, cleaning media and aggressive environments can cause corrosion, pitting and start-up wear. CorrPrevent® helps protect critical contact areas and can be combined with application-specific seals and lubricants.

• Typical applications: food and beverage machinery, filling systems, wet areas, conveyor technology and outdoor equipment.
• Combination: protected surfaces, suitable grease and a sealing system matched to the operating environment.
• Result: reduced corrosion risk, more stable processes and lower maintenance effort.

Sealing systems for rolling bearings and track rollers

In many applications, the seal is the key factor for bearing life. KÜPPER designs contactless, contact, labyrinth and multi-lip sealing systems according to media, temperature, speed, friction torque and available installation space.

• Protection: against dust, liquids, cleaning agents, chemicals and grease leakage.
• Materials: selected according to the application, for example NBR, FKM, PTFE or stainless-steel components.
• Result: longer service life, reduced maintenance and reliable operation under difficult conditions.

Ready-to-install bearing assemblies

Where several machine elements interact, a pre-assembled bearing unit can simplify the entire design. KÜPPER combines bearings, seals, spacers and fastening elements into functional assemblies designed for safe installation and reliable operation.

• Integration: shafts, bolts, flanges, re-lubrication systems, gears or special geometries.
• Production: precision machining, defined cleaning, greasing, pressing, assembly and inspection.
• Result: fewer individual parts, reduced assembly effort and improved functional reliability.

Optimised profiles for track rollers and support rollers

In track roller applications, the outer profile often determines wear, edge pressure and running behaviour. KÜPPER manufactures cylindrical, crowned, V-shaped or customer-specific profiles matched to the mating surface and real operating load.

• Design focus: contact pattern, load distribution, profile geometry and surface quality.
• Result: more uniform contact, reduced surface damage and lower wear on the mating component.
• Documentation: measurement reports, surface values and comparative testing can be provided where required.

From bearing concept to series production

KÜPPER supports customers throughout the complete development process. Engineering, production, assembly and quality assurance work closely together so that technical requirements, prototypes, testing and series production remain transparent from the beginning.

1. Clarify requirements: loads, speeds, temperature, media, installation space, quantities and failure patterns.
2. Develop the concept: bearing type, material, sealing system, lubricant, profile and assembly function.
3. Manufacture samples: prototypes or pre-series parts with defined inspection characteristics.
4. Validate the design: function, assembly, running behaviour and service-life potential.
5. Secure series production: production process, quality assurance, documentation and delivery concept.
