Plain bearings (sleeve bearings) and the shafts they ride

As mentioned earlier — in the FAQ Plain bearings: What are they? — plain bearings are made of many graphite, bronze, and plastics that include PTFE, nylon, and polyacetal. Material improvements have made plastic plain bearings increasingly common, even in demanding motion applications. Shaft material and wear of plain bearings The shafts on which plain bearings […]

More efficient bearing lubrication

The time spent on greasing bushings can be substantial. Although some greasing globally is automated, much re-lubrication is performed by hand using a grease gun. This means that the time spent greasing one grease point totals between three and five minutes for the staff member involved, be they a lube technician, a maintenance engineer or […]

The value of integrating partners early in the design process

Edited by Mike Santora In the traditional product design model, bearing selection isn’t usually a large factor. Not much differentiates one bearing from another, the thinking goes, so why spend time considering the type of bearing to be used when they’re all basically the same? Jonathan Checketts and Kim Evans are on a mission to […]
