Weight: 94-4000kg
For External Gear Type
Inner Diameter: 470-4272mm ,Outer Diameter: 694-4726mm
Weight: 93.1-4000kg
3. Feature: Four-point contact ball slewing bearings contact angle is usually 35°. If there is only a radial load, each steel ball contacts the raceway at four points. If there is only a unidirectional axial load, each steel ball contacts the raceway at two points. It can bear axial loads in two directions as well as a certain eccentric load, i.e. torque. Such kind of bearing has features and properties of both single-row and double-row angular contact ball bearings. If it is used in a high-speed scenario, two-point contact must be ensured for its normal working.
4. Material:50Mn/42CrMo/S48C/42CrMo4/16Mn
Product Description

Four Point Contact Ball Slewing Bearing - Precision Engineered for Heavy-Duty Applications

When you need reliable rotation solutions for heavy machinery, four point contact ball slewing bearing innovation conveys uncommon execution. These specialized heading give smooth rotational development whereas supporting tall hub, outspread, and tilting loads at the same time. The imaginative plan highlights four contact focuses where balls touch the raceways, guaranteeing indeed stack dissemination and predominant soundness. This progressed building makes them basic components in requesting mechanical applications where accuracy and toughness matter most. You'll discover these heading controlling everything from development hardware to wind turbines with surprising efficiency.

What Makes Our Slewing Bearings Different?

MEHI Supply Chain Company brings over a decade of mastery in fabricating exactness bearing arrangements. Our state-of-the-art office houses more than 150 generation hardware sets and 70+ testing rebellious. This incorporates CMM machines, metallographic magnifying instruments, roundness meters, and grinding torque testers.

You advantage from our noteworthy yearly generation capacity:

  • 30,000 sets of long-life mill bearings
  • 40,000 sets of high-precision thin section bearings
  • 10 million pieces of high-end rolling elements

Every bearing experiences thorough quality testing utilizing progressed gear like UT, MT, and ET frameworks. This guarantees you get items that meet the most elevated industry standards.

Technical Specifications

Our bearing comes in three distinct configurations to match your specific needs:

Type Inner Diameter Outer Diameter Weight Range
No Gear 260-4272mm 480-4726mm 55-4000kg
Internal Gear 458-4272mm 662-4726mm 94-4000kg
External Gear 470-4272mm 694-4726mm 93.1-4000kg

Key Features:

  • Contact Angle: 35° for optimal load distribution
  • Material Options: 50Mn, 42CrMo, S48C, 42CrMo4, 16Mn
  • Load Capacity: Handles axial loads in both directions
  • Design: Separable construction for easier installation

How These Bearings Work

The one of a kind four-point contact plan makes numerous stack ways. When you apply as it were spiral loads, each steel ball contacts the raceway at four focuses. Beneath unidirectional pivotal loads, contact happens at two focuses per ball.

This adaptability permits the bearing to handle:

  • Bidirectional axial forces
  • Radial loads
  • Eccentric loads (torque)
  • Combined loading conditions

For high-speed applications, we guarantee two-point contact operation keeps up ideal execution and expands benefit life.

Applications Across Industries

Your equipment benefits from versatile four point contact ball slewing bearing solutions in numerous sectors:

Construction & Heavy Machinery

  • Excavators and bulldozers
  • Tower cranes and mobile cranes
  • Loaders and graders

Energy Generation

  • Wind turbine nacelles
  • Solar tracking systems
  • Oil drilling rigs

Specialized Equipment

  • Military vehicles and tanks
  • Port handling equipment
  • Agricultural machinery
  • Medical devices (MRI machines)
  • Aerospace applications

Why Choose MEHI Bearings?

Superior Load Distribution

The four-point contact plan spreads loads equitably over the bearing surface. This decreases localized push and essentially expands operational life.

Precision Manufacturing

Our progressed generation offices keep up tight resiliences on dimensional exactness, hub runout, and spiral runout. You get heading that perform reliably beneath requesting conditions.

Material Excellence

High-quality steel amalgams give great quality and erosion resistance. Your orientation keep up execution indeed in cruel natural conditions.

Separable Design

The part internal ring plan disentangles establishment and upkeep. You spare time amid gear get together and decrease downtime for bearing replacement.

Quality Assurance

Every product undergoes comprehensive testing protocols. Our quality control process includes:

  • Dimensional confirmation utilizing CMM systems
  • Material composition analysis
  • Load testing beneath reenacted working conditions
  • Vibration and clamor level assessment
  • Surface wrap up inspection

This thorough approach guarantees you get heading that meet or surpass industry specifications.

Custom Solutions Available

We get it that standard arrangements do not continuously meet special application prerequisites. Our building group works with you to create custom bearing arrangements. Whether you require extraordinary materials, altered measurements, or special equip arrangements, we convey custom fitted products.
