Rolling bearings and track rollers for deep-freeze conveyor technology

FOR DESIGN ENGINEERING & TECHNICAL PURCHASING

Bearing technology for your next system design.

Are you developing bakery lines, freezing equipment, packaging machinery or automated cold storage systems? KÜPPER supports the design of rolling bearings and track rollers for your conveying and guidance systems.

Together with your engineering team, we consider installation space, connection dimensions, loads and starting torque. This helps us select an appropriate combination of bearing design, material, lubrication and sealing. Depending on the configuration, applications down to −50 °C are possible.

Integrate into your system
Match geometry, running surfaces and connection dimensions to your design

Account for operating conditions
Consider cold starts, cyclic operation, cleaning and temperature changes together

Plan requirements early
Discuss samples, quantities per system and planned series production

BEARING ARRANGEMENTS ALONG THE PROCESS CHAIN

From the bakery line to the high-bay cold store.

Whether you supply a single machine or integrate several subsystems, we consider the bearing arrangements within your scope of supply and the interfaces between production, freezing, packaging and logistics.

Bakery lines & freezing equipment

Rolling bearings and track rollers for infeed, guidance and transfer stations serving cooling and freezing equipment. Temperature zones and cleaning conditions are considered for each bearing arrangement.

Packaging & handling

Guide and support rollers for frozen product infeed, packaging lines and handling systems – matched to cycle times, changing loads and installation space.

Conveying & palletising

Bearing arrangements in transport, transfer and positioning systems between packaging and storage. Connection dimensions, available conveying force and repeated starts form part of the design process.

Automated cold storage logistics

Track rollers and bearing arrangements for conveying and guidance systems used around high-bay cold stores. Cold starts after standstill and changing operating conditions are considered early in the project.

APPLICATIONS DOWN TO

−50 °C

depending on bearing configuration and operating conditions

The lowest start-up temperature and the temperature during operation are considered separately for each bearing arrangement.

COMPONENTS DESIGNED TO WORK TOGETHER

In the cold, the whole bearing arrangement matters.

Lubricant, seals, loads and movement need to work together. Restarting is particularly relevant when the bearing arrangement has cooled down fully during a standstill.

Starting torque may increase

Account for available drive and conveying force.

Our approach: Assess start-up temperature, standstill duration and movement together with lubrication and sealing.

Lubrication for applications down to −50 °C

Applications down to −50 °C are possible with suitable KÜPPER configurations. Greases with a stated temperature range starting at −40 °C may also be considered following an application-specific assessment.

At lower temperatures, grease becomes more viscous. We therefore consider starting behaviour, load, speed and operating duration when selecting the lubricant and grease quantity.

Sealing against cold and moisture

Condensation at temperature transitions, defrosting and cleaning processes can expose the bearing arrangement to moisture. Seal materials and sealing principles must suit the low temperatures and surrounding media.

For contact seals, their contribution to friction is also included in the design assessment.

More about sealing ↗

Corrosion protection and food environments

Corrosion-resistant materials, stainless steel options or suitable coatings are selected according to moisture, cleaning conditions and component loads.

Where incidental food contact may occur, NSF H1 lubricant options can be considered. Selection is specific to the configuration and its temperature requirements.

FOR YOUR TECHNICAL SPECIFICATION

What must your bearing arrangement deliver?

What installation space and connection dimensions are specified?
What loads and operating cycles are involved?
How cold is the bearing arrangement at start-up?
What drive or conveying force is available?
What cleaning conditions and food contact requirements apply?
What sample and series production quantities are planned?

FROM DESIGN TO SERIES PRODUCTION

Your drawing. Our starting point.

Include the bearing arrangement early in your system planning. Together, we review design, interfaces and operating conditions for rolling bearings, track rollers, guide rollers and support rollers.

Installation space, running surfaces and connection dimensions determine the geometry. For plastic-coated track rollers, the suitability of the coating material for the intended low temperature also forms part of the design assessment.

Together with engineering and technical purchasing, we also discuss sample requirements, quantities per system, planned call-offs and requested delivery dates. This allows technical requirements and procurement planning to be developed together.
