INA SL045014‑PP‑C3 - Cylindrical Roller Bearing 70x110x54 mm

Applications

This double-row cylindrical roller bearing is designed for applications requiring very high radial load capacity, particularly in heavy industrial machinery, such as gearboxes, rolling mills or large drive shafts. The full-complement design (no cage) provides maximum number of rollers, making it suitable for industrial use where minimal maintenance and long service life are critical.

Key Advantages

• High radial load capacity: Thanks to the full-complement design and double-row rollers, the bearing handles significant radial forces with stability and durability.

• Sealed on both sides (“PP” suffix): Equipped with lip seals on both sides to protect the bearing from dust and contaminants — ideal for harsh industrial environments.

• Increased internal clearance (“C3” suffix): Allows for thermal expansion of shafts or housings and improves reliability in variable temperature conditions.
  

• Compact size with heavy-duty performance: With dimensions 70 mm (inner diameter) x 110 mm (outer diameter) x 54 mm (width), this unit fits in constrained spaces while delivering industrial-grade durability.

Technical Data

• Inner diameter (d): 70 mm

• Outer diameter (D): 110 mm

• Width (B): 54 mm

• Design: Double-row cylindrical roller bearing, full complement (no cage)

• Seal: Lip seals both sides (“PP”)

• Internal clearance: C3 (greater than standard)

• Typical dynamic radial load rating: ~175 000 N

• Typical static radial load rating: ~275 000 N

This bearing is optimally applied in industrial applications, such as gearboxes, shafts, conveyor drives, heavy-duty plant equipment — in short: any unit requiring a robust, high-radial-capacity bearing with minimal axial movement and high reliability.

FAQ

1. What does the suffix “PP” indicate?
“PP” means the bearing is equipped with lip seals on both sides. These seals protect the bearing interior from dust and contaminants and help retain lubricant, enhancing service life.

2. What is the significance of “C3” clearance?
“C3” means the radial internal clearance is greater than standard. This additional freedom allows for thermal growth of the shaft or housing and is beneficial in applications with fluctuating temperatures or heavy loads.

3. Is this bearing designed for axial loads?
No. This model is optimized for radial loads. The double-row cylindrical design is not primarily meant for significant axial forces. For axial loads, you should use bearings designed specifically with axial load capacity.

4. How to choose this bearing as a replacement?
Ensure the dimensions (70x110x54 mm) match your shaft and housing. Confirm you require sealed design (PP) and C3 clearance. If your application involves heavy radial loads and standard speeds, this model is an appropriate choice.

5. What maintenance considerations apply?
Although the bearing has sealed design and high durability, regular monitoring of lubrication condition, operating temperature and shaft alignment is still recommended for long service life.
