Features and Benefits
No Gear Slewing Bearing
The absence of integral gears reduces your system complexity and allows you to implement alternative drive mechanisms such as friction drives, external drive wheels, or direct motor coupling—based on your torque and speed requirements.
Multi-Directional Load Handling
The raceway geometry enables simultaneous support of axial, radial, and moment loads. This eliminates the need for multiple bearing installations in your rotational assembly.
Compact Cross-Section
Optimized rolling element arrangement delivers high load ratings within minimal radial and axial space. You gain more room for other mechanical components in space-constrained designs.
Low Friction Coefficient
Precision-ground raceways and carefully selected rolling element geometry minimize rotational resistance. This reduces your drive motor requirements and energy consumption during operation.
Customizable Mounting Interface
We machine bolt hole patterns according to your flange dimensions and bolt circle requirements. Standard or metric threading options ensure compatibility with your existing equipment.
Enhanced Sealing Protection
Integrated seals prevent contaminant ingress while retaining lubrication. This extends maintenance intervals and improves reliability in dusty or humid environments.
Applications
Our No Gear Slewing Bearing serves diverse industrial and specialized equipment:
Development and Fabric Handling
Small excavators, ethereal work stages, forklift rotators, and loader rotational components advantage from the compact plan and dependable stack support.
Medical Imaging Equipment
CT scanners and X-ray gantry revolution frameworks require the smooth, vibration-free movement these heading give for exact demonstrative imaging.
Industrial Automation
Robotic arms, welding positioners, and revolving ordering tables utilize these orientation for exact precise situating and persistent revolution cycles.
Renewable Vitality Systems
Solar following clusters utilize gearless slewing orientation to alter board introduction all through the day with negligible support requirements.
Entertainment and Display
Stage apparatus, turning stages, and presentation turntables depend on smooth, calm revolution for proficient presentations.
Installation Guide
Pre-Installation Inspection
Verify bearing measurements coordinate your hardware determinations. Check mounting surfaces for levelness inside 0.1mm per meter. Evacuate all defensive coatings and clean mounting flanges.
Alignment Procedure
Position the bearing on the lower mounting surface. Guarantee the jolt gap design adjusts accurately. Utilize arrangement pins if given in your plan to avoid revolution amid assembly.
Bolt Fixing Sequence
Apply jolts in a star design, continuously expanding torque to the indicated esteem. This avoids mutilation of the bearing rings. Suggested torque values depend on jolt review and diameter—consult our building group for particular requirements.
Initial Lubrication
Fill oil areolas concurring to the bearing volume determination. Pivot the bearing a few transformations to disperse oil equally over the raceway surfaces.
Final Checks
Measure rotational torque to confirm appropriate preload. Check for smooth turn without official or over the top resistance. Review seal contact for appropriate engagement.

Maintenance and Care
Lubrication Schedule
Relubricate each 100 working hours in ordinary conditions, or more as often as possible in dusty situations. Utilize lithium-based oil with NLGI Review 2 consistency unless something else specified.
Periodic Inspection
Every 500 hours, check mounting jolts for legitimate torque maintenance. Review seals for harm or wear. Tune in for bizarre clamor demonstrating raceway harm or insufficient lubrication.
Cleaning Procedures
Remove amassed flotsam and jetsam from outside surfaces utilizing compressed discuss or delicate brushes. Dodge high-pressure washing straightforwardly on seal regions, which may drive contaminants into the bearing.
Storage Recommendations
Store unused orientation on a level plane in dry conditions underneath 60% mugginess. Keep up defensive coatings and wrapping until establishment to anticipate corrosion.
FAQ
Q: What's the distinction between adapted and gearless slewing bearings?
A: Gearless adaptations have no fundamentally teeth on the rings, giving you flexibility to actualize custom drive frameworks. Adapted heading incorporate machined teeth for coordinate pinion engagement.
Q: How do I select the adjust bearing sort for my application?
A: Consider your stack size, speed necessities, accessible mounting space, and working environment. Our designing group can survey your details and prescribe the ideal configuration.
Q: Can you make heading to non-standard dimensions?
A: Yes, we routinely create custom orientation based on client drawings or test units. We can alter measurements, jolt designs, and seal courses of action to coordinate your requirements.
Q: What's your commonplace generation lead time?
A: Standard arrangements transport inside 2-3 weeks. Custom plans require 4-6 weeks depending on estimate and complexity.
Q: Do you give establishment support?
A: We offer specialized direction, establishment strategies, and torque details with each bearing. On-site help can be organized for basic establishments.
