Slewing bearings
Supply for OEM Builds and Bearing Replacements
Ningguo Swbtec Industry Co., Ltd. supplies complete slewing bearing assemblies for rotating equipment. For a new design, the bearing specification starts with loads, installation space, gear drive, and the surfaces that support each ring.
For a replacement, the existing bearing and machine are the starting points. A matching review compares the bore and outside diameter, ring height, bolt circles, hole count, gear geometry, and running clearance. Machine model and part number help identify candidates; the drawing confirms the interface before manufacture.
Match the Bearing Structure to the Load
A slewing bearing carries axial and radial forces while resisting overturning moment. Select the rolling-element arrangement from the combined load case, required stiffness, space, and operating duty.
| Design | Useful first screen | Where to look in this range |
|---|---|---|
| Single-row ball | Compact general-purpose rotation with combined loading | Single Row Ball Slewing Bearing |
| Double-row ball | More ball capacity when a single row is insufficient within the available envelope | Double Row Ball Slewing Bearing |
| Crossed roller | Higher stiffness and moment support for a given layout | Cross Roller or High Precision Cross Roller designs |
| Three-row roller | Heavy axial, radial, and moment loads in large equipment | Three Row Roller Slewing Bearing |
The gear and mounting arrangement are separate decisions. Choose internal or external teeth to match the pinion position, or a gearless ring when the drive is supplied elsewhere. SWBTEC lists QN for internal teeth, QW for external teeth, and QU for gearless rings; its model tables provide dimensions and mounting-hole data, plus gear data for toothed rings. Confirm the final load rating against the selected model's data and actual duty cycle.

Information Needed for Fit and Pricing
The same model name can cover different gear, mounting, and clearance configurations. A drawing or the dimensions below let SWBTEC check the interface and quote the specified build.
- Loads and motion: axial and radial loads, overturning moment, speed, duty cycle, and shock conditions.
- Mounting envelope: bore and outside diameter, ring height, bolt circles, hole size and count, and which ring rotates.
- Drive and environment: gear location, module and tooth count if applicable, pinion layout, temperature, contamination, and lubrication conditions.
- Replacement references: equipment make, model and serial number, existing part number, controlled drawing, and clear photos of the old ring and gear.
- Order details: quantity, delivery destination, and any inspection documents required with the shipment.
When comparing supplier quotes, confirm that each offer identifies the same bearing configuration, inspection scope, documents, packaging, and delivery basis.
Send Your Bearing RequirementsManufacturing and Inspection at SWBTEC
SWBTEC's production materials describe incoming forged-ring checks, rough machining, ultrasonic testing, raceway induction hardening, gear and hole machining, finish work, and assembly. The process links material condition to the ring, raceway, mounting, and gear geometry required by the installed machine.
The company's inspection materials cover dimensions, axial and radial clearance, runout, raceway hardness, and gear checks where teeth are present. For an OEM order, identify the drawing revision and specify which measured results and material or heat-treatment records should accompany the finished bearing. Request records tied to the ordered model and serial or batch number.
