Product Description

Data Sheet

High-Performance Cylindrical Roller Bearings for Heavy Machinery – Customized & Ready to Ship

Engineered for extreme loads, high temperatures (up to 150°C), and rapid delivery – precision-built for metallurgical, mining, and port machinery.

Cylindrical Roller Bearings are the backbone of industrial machinery requiring unmatched radial load capacity and durability. At LUOYANG INNO BEARING CO., LTD, we specialize in manufacturing bearings that thrive under punishing conditions—whether it's a steel mill furnace operating at 150°C or a port crane enduring 10,000+ impact cycles. With 30+ years of engineering expertise, our solutions combine precision, speed, and reliability to minimize downtime and maximize productivity.

product-750-750

Technical Specifications & Customization

Core Features

✔️ Sizes: Standard (φ50mm–φ5000mm) & non-standard dimensions

✔️ Radial Load Capacity: Up to 300kN static load

✔️ Material: High-purity GCr15 steel with vacuum degassing

✔️ Precision: P4-grade tolerances for minimal vibration

✔️ Temperature Range: -30°C to +150°C (ceramic-coated rollers available)

Tailored Solutions

Bore/OD Modifications: Adjust dimensions within ±0.005mm accuracy.
Cage Materials: Choose stamped steel, brass, or polymer for noise/load needs.
Sealing: Labyrinth seals for dust-heavy environments; contact seals for wet conditions.

Built for Demanding Industries

1. Metallurgy & Steel Production

Our Cylindrical Roller Bearings withstand continuous 150°C heat in rolling mills, with slag-resistant coatings to prevent material buildup.

2. Port Machinery & Mining

Shock-absorbing double-row designs handle sudden 300-ton loads in crane slewing rings. Mining-grade bearings last 2x longer in corrosive crushers.

3. Wind Energy & Heavy Machinery

Corrosion-resistant polymer seals protect offshore turbine bearings from salt spray (1,000+ hours ASTM B117 compliance).
