One of the primary reasons for taking PQQ before bed is its potential impact on sleep quality. A good night’s sleep is essential for recovery and rejuvenation, allowing the body and mind to heal from daily stressors. Research suggests that PQQ may positively affect sleep patterns by promoting relaxation and reducing stress levels. This could be attributed to its ability to enhance brain function and neuroprotection, benefits that are particularly critical for those struggling with sleep issues. By supporting cognitive function and reducing anxiety, PQQ may help create an environment conducive to restful sleep.

In situations where the shaft has splines or an integral gear on the end, you’ll want to take precautions. These gears and splines often have very sharp edges that are quite detrimental to the seal’s integrity. You may use an installation sleeve that will allow the seal to slide past these hazards undamaged.



An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.
