Choose a bearing configuration
Start with the load path and drive layout. The bearing must carry the axial load, radial load and overturning moment that occur together; mounting stiffness and the duty cycle also affect the final size.
| Configuration | Best starting point | Check before selecting |
|---|---|---|
| Rouleau à trois rangées | Heavy combined loads in large rotating equipment | Available installation space and support structure stiffness |
| Internal gear | A drive pinion inside the ring diameter | Pinion position, gear geometry and service access |
| Without gear | A separate drive arrangement or a rotation point without an integral ring gear | How the equipment will rotate and transmit torque |
| Cross roller | Combined loads where roller layout and rotational accuracy matter | Mounting accuracy, load spectrum and any required gear arrangement |
Use the product drawings and load data to confirm a specific bearing. A configuration label alone does not establish its capacity.
What to send for an accurate quote
Send a drawing or existing part number when available. For a new design, include the following project data so SWBTEC can identify a suitable model and quote the same configuration you intend to install.
- Loads: axial force, radial force and overturning moment for the operating cases that occur together, including shock or start and stop conditions.
- Interface: outside and inside diameter limits, overall height, bolt circle, hole pattern, rotating ring and available support structure.
- Drive: internal, external or no gear; for geared rings, share pinion data and the required gear mesh.
- Operation: rotation speed or oscillation angle, duty cycle, temperature, contamination and lubrication access.
- Purchase: quantity, delivery destination and any inspection or documentation requirement.

Compare the four configurations, then open the matching product page for its model table and drawing dimensions.

Couronne à trois rangées de rouleaux
Three roller rows distribute combined loads in large rotating machinery, including heavy equipment and port equipment. Review the listed model and gear configuration against your support structure.
- StructureRouleau à trois rangées
- Listed series130 / 131 / 132 / 133 / 134
- Gear optionsWithout, external or internal

Couronne d'orientation avec engrenage interne
Internal teeth place the ring gear inside the bearing envelope. Match the pinion layout, gear data and mounting pattern to the machine drawing.
- EngrenagesInternal
- Example listed modelSW-414N.20
- Table includesDimensions, mounting and gear data

Couronne d'orientation sans engrenage
A gearless ring provides the bearing interface when the equipment uses a separate way to create rotation. Confirm loads, flange geometry and how torque reaches the rotating structure.
- EngrenagesNone
- Example listed modelSW-414.20
- Table includesDimensions, mounting and weight

Couronne d'orientation à rouleaux croisés
Crossed rollers support axial, radial and moment loads in one ring assembly. Confirm the bearing type, mounting accuracy and gear option required by your application.
- StructureSingle-row cross roller
- Listed type codes110 / 111 / 112 / 113 / 114
- Gear optionsWithout, external or internal
Replacing an existing slew bearing
A matching outside diameter does not make two rings interchangeable. Compare the bolt circles, hole counts, mounting height, rotating ring, gear module and tooth count, clearance and sealing arrangement. Share the old drawing or part number along with photographs of both mounting faces.
For a change from ball to roller construction, or from one row arrangement to another, recalculate the simultaneous loads and check the connected structure and bolts. Confirm the replacement against the new product drawing before ordering.
What changes the quoted price
Price depends on the model and the work required to make it: ring size, load capacity, gear machining, accuracy, material and heat treatment, seals, quantity and required delivery schedule. A replacement that needs a changed bolt pattern or tooth geometry also changes the manufacturing scope.
Ask the sales team to identify the selected model and drawing revision, included inspection records, packaging and delivery terms on the quotation. This makes offers with different configurations easier to compare.
Manufacturing and inspection points
SWBTEC's product materials describe incoming forging checks, ultrasonic inspection after rough turning, raceway heat treatment, gear and hole machining, final assembly and recorded inspection. The relevant checks depend on the ordered design.
For a drawing-specific order, agree on the inspection record before production. Typical recorded items include overall height, mounting dimensions, axial and radial clearance, ring runout, raceway hardness and smooth rotation. A geared ring can also require gear measurements; the accepted limits should match the approved drawing.
