Four Row Cylindrical Roller Bearing

High-Capacity Four Row Cylindrical Roller Bearings for Extreme Industrial Environments (150°C/Heavy Loads)

Customized solutions for metallurgical, mining, and port machinery with 48-hour standard delivery and ISO-certified durability.

Engineered for Extreme Performance

When your equipment faces relentless heavy loads, high temperatures, or shock impacts, our Four Row Cylindrical Roller Bearings deliver unmatched stability. Designed with four rows of precision-ground rollers and reinforced spacer rings, these bearings distribute stress evenly, achieving 3.5x higher radial load capacity than single-row designs. Whether you're operating rolling mills at 150°C or port cranes lifting 1,000+ tons, our solutions ensure minimal downtime and maximum productivity.

Core Specifications

• Dimensions: Inner Diameter 100mm–5000mm (custom sizes available)
• Load Capacity: Radial up to 12,000kN | Axial up to 3,500kN
• Temperature Range: -50°C to +150°C (high-purity steel + advanced heat treatment)
• Precision: P4/P5 grades for smooth operation under heavy loads
• Lubrication: Pre-lubricated with high-temperature grease or IoT-enabled oil systems

  

Where They Excel?

Metallurgy

Withstand scorching 150°C environments in rolling mills, backed by carburized steel that resists thermal deformation.

Mining

Absorb shock loads ≥2.5x nominal capacity in crushers, thanks to double-crowned rollers and brass cages.

Ports

Operate at ≤35dB noise levels in crane trolleys, using corrosion-resistant coatings for saltwater environments.

FAQ

1. How do your bearings handle 150°C temperatures?

We use carburizing heat treatment on ultra-clean steel, enhancing thermal stability without compromising load capacity.

2. Can you make bearings over φ5000mm?

Yes. Our modular production system allows custom outer diameters up to φ5000mm with a 20-day lead time.

3. How is the 99.9% quality rate achieved?

Raw materials are tested via UT/MT, followed by in-process checks on roller alignment, hardness, and clearance consistency.

4. Do you support legacy machinery upgrades?

Our retrofit kits include pre-machined spacer rings and installation guides tailored to your equipment’s specs.

5. What lubrication options exist for mining?

Choose graphite-based grease for high temperatures or automated oil systems with IoT viscosity sensors.
