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.

What Our Clients Say About Us

Testimonial Image
"I want to take this opportunity to thank the Bushings Incorporated team that recently helped us get our automated assembly line up and running.  For years our line required our rubber insulated overmolds be manually inserted due to several failed attempts to get an automated press to properly insert the bushings.  The Bushings Incorporated team was able to help by working with our manufacturing engineers to develop fixtures, and procedures that were able to get the automated press up and running.

With the new press up and running, the consistency has been great, and the operator is very happy with the new process.  The operator says that the new press and fixturing is doing a good job at installing the bushings straight and consistent.  He has experienced no “mushrooming” or tearing of the bushings with the automated press (this was the reason for manually inserting them for so many years).  The operator also says that the job is much easier on him, and the production level is up due to the new process.

The help that was received to improve our process was above and beyond.  That kind of support is needed and appreciated, and while most vendors lack in their support, it is my feeling that Bushings Incorporated and their team have gone one step above.

Thanks again for the support!"
