SW 6308LUE Deep Groove Ball Bearing - Single Contact Seal (LU) - High Performance (E) | 40x90x23mm
The SW 6308LUE is a high-performance single-row deep groove ball bearing engineered for applications demanding superior load capacity and extended service life under challenging industrial conditions. This robust bearing features the critical 6300 Series dimensions (40mm bore, 90mm outer diameter, 23mm width), making it a standard replacement for electric motors, gearboxes, and industrial pumps. The 'LUE' designation signifies a specialized contact seal (LU) on one side, which effectively retains high-quality grease while excluding contaminants like dust and moisture. Furthermore, the 'E' suffix indicates an optimized internal geometry and ball complement, resulting in enhanced dynamic load ratings (Cr ≈ 55.3 kN) and reduced running noise compared to standard designs.
Designed by SW to deliver exceptional operational reliability, the 6308LUE reduces the total cost of ownership (TCO) by minimizing maintenance intervals and preventing premature failure caused by lubrication loss or particle ingress. Its premium-grade bearing steel construction ensures high fatigue strength, even when subjected to oscillating loads or medium-high speed operation (Grease Limit Speed: 7,500 rpm). Ideal for mission-critical machinery in manufacturing, mining, and material handling sectors, the SW 6308LUE provides the optimal balance of sealing efficiency, high-load capability, and precision running accuracy.
Key Features
