Quiets New and Used Equipment

The “Silent-Lign” solves your complex engineering problems, both in new product design and replacement on noisy, new and used equipment. Field proven, these Pillow Blocks accommodate maximum shaft misalignment, plus quiets noisy equipment by eliminating vibration.

Featuring the “Silent-Lign” sleeve bearing cartridge, these Pillow Block assemblies offer low initial cost, and minimal maintenance expense, while providing durable, reliable service. “Silent-Lign” bearings are oil impregnated. The porous bronze sleeve acts as a metallic sponge. It constantly obtains sufficient lubrication through absorption with the application of a few drops of oil as necessary. The neoprene wall is an oil resistant flexing medium. It can accommodate a high angle of torsional movement. As the amount of misalignment increases, the thickness of the neoprene is increased and its length is reduced. This permits the entire I.D. of the bearing to be utilized, with no shaft gall at the edges. The neoprene wall also acts as an isolating agent, silencing vibration, and eliminating the transmission of noise. The outer shell of both the bearing cartridge, and the pillow block is plated steel. The pillow block features a sturdy rustproof (zinc dichromate plated), stamped steel, and welded mounting bracket with slotted mounting holes.
