High Load SL04 5010 PP NR 50x80x40mm Double Row Cylindrical Roller Bearing Full Complement

Product Overview：

When your heavy-duty machinery demands exceptional radial load capacity, reliable sealing, and easy installation, the SL04 5010 PP NR double row cylindrical roller bearing delivers uncompromising performance. Its robust full complement, double-row design eliminates the need for a cage, maximizing the number of rolling elements and delivering exceptional load-carrying capability in a compact envelope.

Key Features

• High Radial and Impact  Load Capacity
  The full complement, double-row design delivers a dynamic load rating of 102 kN and a static load rating of 151 kN. The cylindrical roller geometry provides line contact with the raceways, distributing loads over a larger area than ball bearings, making it exceptionally resistant to impact and shock loads.
• Sealed for Contamination Protection
  The double contact seals on both sides keep lubricant in and contaminants out. This sealing extends bearing life in dirty, dusty, or outdoor environments, reducing maintenance frequency and downtime.
• Locating Bearing Capability
  The rib configuration (central rib on outer ring, three ribs on inner ring) provides reliable axial guidance of the rollers. This design ensures stable operation even under heavy loads, vibration, and misalignment conditions.
• Long Service Life in Demanding Environments
  The combination of full complement rollers, robust sealing, and high-quality bearing steel ensures long service life even in the most demanding applications. The bearing is engineered for harsh operating conditions and heavy loads.
• Globally Standardized and Interchangeable
  The SL04 5010 PP NR conforms to international standards and is directly interchangeable with bearings from INA (SL045010-PP-2NR), NTN (SL04-5010LLNR), FBJ, and other leading manufacturers. This standardization simplifies sourcing and replacement.
• Moderate Speed Capability
  With a grease lubrication limiting speed of 2,600 RPM, this bearing is ideal for medium to low-speed, heavy-load applications. It is specifically designed for applications where load capacity is the priority over high rotational speeds.

Application Scenarios

The SL04 5010 PP NR double row cylindrical roller bearing is a versatile component trusted across numerous heavy-duty industries:

• Crane Sheaves and Pulley Systems
  The bearing’s full complement design and high load capacity make it the preferred choice for crane sheaves, hoist pulleys, and wire rope sheaves. The snap ring feature simplifies installation in sheave assemblies.
• Construction and Earthmoving Equipment
  Excavators, loaders, bulldozers, and backhoe loaders use SL04 series bearings in track rollers, idlers, and pivot points.
• Hoisting and Lifting Equipment
  Overhead cranes, hoists, winches, and elevator sheaves benefit from the bearing’s high radial load capacity and impact resistance.
• Steel Mills and Metallurgical Equipment
  Rolling mill guide rollers, conveyor rollers, and heavy material handling equipment rely on the SL04’s robust construction and sealing.
• Heavy Machinery and Industrial Equipment
  Presses, forming equipment, and heavy-duty conveyors use SL04 bearings for reliable, long-lasting performance.
• Port and Marine Equipment
  Presses, forming equipment, and heavy-duty conveyors use SL04 bearings for reliable, long-lasting performance.
• Mining and Aggregate Equipment
  Crushers, screens, and heavy conveyors require bearings capable of withstanding extreme loads and abrasive environments.
• Agricultural Machinery
  Heavy-duty harvesters, balers, and tillage equipment use SL04 bearings in high-load pivot points and roller assemblies.
