The sound-absorbing characteristics of mineral fiber ceiling boards are among their most significant benefits. These boards are designed to reduce noise levels in a space by absorbing sound waves, which limits echoes and reverberation. This makes them an ideal choice for areas such as classrooms, conference rooms, and healthcare facilities, where clear communication is essential. The Noise Reduction Coefficient (NRC) rating of these boards often falls between 0.5 to 0.9, indicating excellent sound absorption capabilities.

○ NBR - The maintenance of oil seals is also crucial to ensure their longevity and effectiveness. Regular inspections should be performed to check for signs of wear, damage, or contamination. If any issues are detected, the seal should be replaced immediately to prevent further damage to the machinery.
When the total eccentricity is excessive, the sealing edge of the seal lip cannot accommodate shaft motions and leakage may occur.
Total eccentricity is the sum of shaft runout and the housing-bore eccentricity.
Total eccentricity, shaft runout and housing-bore eccentricity are generally expressed in TIR (Total Indicator Reading).
