Product Description

 Double-row Full Complement Cylindrical Roller Bearing

SL045010 (common suffix - PP) is a double-row full complement cylindrical roller bearing, characterized by high radial load capacity, high rigidity, and the ability to withstand moderate axial forces in both directions. It is specifically designed for Low-speed, Heavy-load, and dusty/humid environments, and is primarily used in lifting pulleys, speed reducers, construction machinery, and metallurgical and mining applications.

Specification

I. Bearing Introduction (SL045010-PP)
1. Basic Parameters (I.N.A Standard)
Type: Double-row Full Complement Cylindrical Roller Bearing (positioning type)
Dimensions: Inner diameter 50mm, outer diameter 80mm, width 40mm
Load: Radial dynamic load 102kN, static load 151kN
Speed: Grease lubrication limit approximately 2600r/min
Seal: PP = double-sided contact seal (class 3 dustproof and waterproof)
Structure: Outer ring with retaining groove (with snap ring), inner ring with three retaining edges, full complement design (no cage)
2. Core Features
Ultra-High Radial load Capacity: Full complement + double row, significantly higher load capacity than ordinary cylindrical roller bearings of the same size
High rigidity: Suitable for impact, heavy load, and low deformation conditions
Bidirectional axial positioning: Can withstand moderate bidirectional axial forces, providing both radial and axial positioning
Reliable sealing: PP Suitable for dusty, humid, and impurity-rich environments.
Easy installation: The outer ring retaining groove facilitates axial fixing; the inner ring can be split (some models).
