FAQ - What is a Sleeve Bearing? - GGB

Sleeve bearings consist of a metal, plastic or fiber-reinforced composite sleeves that reduce vibrations and noise by absorbing friction between two moving parts using a sliding motion. Sleeve bearings offer several advantages, including lower cost, less maintenance, greatly reduce noise at low speeds and easier installation. Sleeve bearing

The New Hybrid Thin-Shell Precast Wall System - National …

16/7/2009· Thin-shell precast uses up to 75 percent less concrete than the 4 to 8 inches of concrete thickness in conventional precast panels. This means a thin-shell wall weighs about 35 pounds per square foot (psf) including the framing instead of 100 psf. And if a cellular concrete mix is used, the wall can weigh as little as 12 psf.
