4 Point Contact Ball Bearing

4 Point Contact Ball Bearing – Precision Engineering for Heavy-Duty Applications

When your equipment demands robust axial load capacity in both directions without compromising space, the 4 Point Contact Ball Bearing delivers the perfect solution. This specialized rolling bearing combines the load-carrying capacity of double-row angular contact bearings within a compact single-row structure. At Luoyang Hengguan Bearing Technology, we manufacture these high-performance bearings with diameters ranging from 50mm to 10,000mm, serving industries where precision and reliability are non-negotiable. Our product features an innovative raceway design where each steel ball contacts the inner and outer rings at four distinct points, enabling efficient bidirectional axial load support alongside limited radial loads.

Product Details

Our four-point contact ball bearings feature an integral construction with specially designed raceways. The unique geometry allows each rolling element to make contact at four points, distributing loads evenly across the bearing structure. This design eliminates the need for dual-row configurations in many applications.

Core Construction:

· Rings:Manufactured from high-strength 50Mn or 42CrMo alloy steel

· Rolling Elements:Precision-ground GCr15 bearing steel balls with controlled hardness

· Cage Assembly:Engineered for optimal ball spacing and lubrication distribution

· Contact Geometry:Four-point contact configuration for bidirectional axial load support

The separable design allows independent mounting of the outer ring assembly and inner ring halves, simplifying installation in confined spaces.

Technical Specifications

Features and Benefits

Even Load Distribution

The 4 Point Contact Ball Bearing spreads loads across multiple contact areas. This reduces stress concentrations and extends service life in cyclical loading conditions.

Compact Footprint

You get double-row performance in a single-row package. This saves axial space and reduces overall assembly weight—critical for mobile equipment and robotics.

Bidirectional Axial Capability

The symmetrical contact design handles thrust loads from either direction without orientation concerns. This simplifies installation and accommodates reversing applications.

Separable Construction

Independent ring components facilitate mounting in housings with limited access. You can position components sequentially rather than as a complete assembly.

High Rotational Accuracy

Precision grinding of raceways and controlled ball geometry minimize runout. This supports smooth operation in positioning systems and measuring equipment.

Material Durability

Heat-treated alloy steel rings resist deformation under load. Hardened bearing steel balls maintain geometry through millions of rotation cycles.

Applications

Construction Machinery

Excavator swing drives, crane turntables, and concrete pump turrets rely on these bearings for smooth slewing motion under heavy loads.

Port Handling Equipment

Ship-to-shore cranes and straddle carriers use large-diameter versions to support rotating booms and lifting mechanisms.

Industrial Robotics

Joint assemblies in multi-axis robots benefit from the compact design and precision rotational performance.

Wind Turbines

Yaw and pitch systems utilize these bearings to adjust blade angles and nacelle orientation in varying wind conditions.

Medical Imaging

CT scanner gantries require smooth, accurate rotation—applications where our P5 and P4 precision grades excel.

Tunnel Boring Machines

Main bearing assemblies support cutter heads while accommodating thrust forces and misalignment during excavation.

Installation Guide

Pre-Installation:

1. Clean mounting surfaces thoroughly to remove debris and old lubricant

2. Inspect raceway surfaces for damage or contamination

3. Verify Shaft and housing dimensions match bearing tolerances

Mounting Procedure:

4. Position inner ring halves on the shaft, aligning bolt holes if applicable

5. Apply specified lubricant to raceways and rolling elements

6. Install outer ring with ball and cage assembly

7. Secure retaining components per your equipment specifications

8. Check for smooth rotation by hand before applying full loads

Critical Checks:

· Ensure proper axial clearance per application requirements

· Verify alignment to prevent edge loading

· Confirm lubrication passages are unobstructed

Maintenance and Care

Oil Schedule:

Grease-lubricated orientation regularly require relubrication every 500-2000 working hours, depending on stack and speed. Oil-lubricated frameworks require intermittent oil investigation and channel replacement.

Inspection Points:

· Monitor working temperature—sustained increments demonstrate inadequately grease or overloading

· Listen for irregular commotion designs recommending defilement or wear

· Check for grease spillage at seals

Storage:

Store heading in unique bundling in a dry, temperature-controlled environment. Apply rust preventive if capacity surpasses six months.

FAQ

Q: Can these orientation handle unadulterated spiral loads?

A: Whereas outlined basically for hub loads, they bolster constrained outspread loads. For radial-dominant applications, consider profound groove or round and hollow roller bearings.

Q: What's the distinction between P5 and P6 accuracy grades?

A: P5 offers more tightly dimensional resistances and way better rotational precision. Select P5 for exactness situating gear, P6 for common mechanical applications.

Q: Do you give custom sizes past your standard range?

A: Yes. We make non-standard heading from 50mm to 10,000mm diameter with custom raceway arrangements for extraordinary applications.

Q: How do I select the fitting preload?

A: Our building group can suggest preload values based on your stack range, speed, and solidness prerequisites. Contact Us with your application details.

Q: What causes untimely bearing failure?

A: Common causes incorporate defilement, insufficient grease, misalignment, and operation past appraised loads. Appropriate establishment and upkeep avoid most issues.
