Slewing Rings
Precision Slewing Ring Bearings for Heavy Industry
Large rotating equipment demands bearings that can handle serious loads from multiple directions at once. That's exactly what slewing ring bearings do. These large diameter bearings combine radial, axial, and moment load capacity into a single unit, making them the go to choice for cranes, excavators, wind turbines, and radar systems. We supply precision slewing ring bearings across the UK for defence, medical, renewable energy, and industrial automation applications.
Why Slewing Ring Bearings Work
Choosing the right slewing ring bearings makes a real difference to your equipment performance and maintenance costs.
- Single bearing handles loads from all directions, reducing assembly complexity
- Gear teeth (internal or external) integrate directly into the bearing ring
- Multi row assemblies multiply load capacity without increasing diameter
- Thin section designs fit space constrained applications
- Hybrid technology combines steel raceways with aluminium housings for weight savings
Our team works with you to select slewing bearings that fit your space constraints and exceed your load specifications.
Thin Section Bearing Configurations and Materials
We supply three configurations to meet diverse application requirements:
Radial Contact Bearings handle perpendicular loads efficiently in compact spaces.
Angular Contact Bearings manage combined radial and axial forces. Pairing increases load capacity and moment load resistance.
Four Point Contact Bearings provide bidirectional axial load capability within minimal cross sectional dimensions. We analyse loading conditions to specify optimal configurations.
How We Select the Right Bearing
Getting the right slewing ring bearings starts with understanding your actual operating conditions. Here's how we work:
- Review your load data, rotation speeds, and environmental factors
- Calculate required capacity with appropriate safety margins
- Recommend bearing type, material grade, and sealing arrangements
- Specify water resistant greases and improved sealing for marine environments
- Provide installation guidance including mounting surface preparation and fastener selection
We've seen too many projects fail from overlooked details like galvanic corrosion or improper mounting surface flatness. Our engineers get the specification right the first time.
Our Slewing Ring Bearing Range
We provide bearing services for OEMs and maintenance teams across multiple sectors.
- Standard and custom bearings from 200mm to 5000mm+ diameter
- Single row, double row, triple row, and crossed roller configurations
- Internal gear, external gear, and gearless options
- Marine grade alloys and corrosion resistant materials for offshore applications
- Non magnetic stainless steels and ceramic elements for MRI scanners
For applications running at high operating temperatures, we can specify high temperature bearings with appropriate materials and lubricants. We supply FDA compliant materials and food grade lubricants for pharmaceutical and food processing environments.
Technical Expertise You Can Count On
We're bearing specialists with decades of hands on experience solving real problems. Not distributors reading from a catalogue.
- Defence systems requiring corrosion resistance for marine and desert deployment
- Medical imaging equipment demanding micron level precision and whisper quiet operation
- Wind turbine yaw and pitch systems operating in exposed environments
- Industrial automation requiring high speed rotation with exceptional positioning accuracy
- Clean room and food processing applications with stringent hygiene requirements
When a bearing fails, we ask why. We've resolved premature failures by specifying better sealing arrangements and selecting materials that handle the actual operating environment.
Get the Right Slewing Bearing First Time
Slewing ring bearings are too important to get wrong. The bearing you choose affects equipment reliability, maintenance costs, and operational safety for years to come.
Whether you need a thin section bearing for a tight envelope or a custom engineered solution for marine, desert, or arctic environments, we have the technical knowledge to deliver.
Applications Across Industries
Slewing ring bearings support demanding applications where failure isn't an option. We work to ISO, DIN, ABMA, and AGMA standards with full traceability on materials and manufacturing. We're working toward ISO 9001:2015 and AS9100D:2016 certification.
