Bearing sleeves offer several advantages, including lower cost, less maintenance, greatly reduce noise at low speeds and easier fixing. Bearing sleeves‘ performance is also marked by a higher load bulk, especially shock load conflict due to their greater contact zone.
Bearing sleeves with a conformal liner compensate for misalignment matters and vibration damping, these one-piece strategy low-friction bearings decrease housing dimensions and weight by having a thin wall section.
Bearing sleeves can be made from bronze, steel or stainless steel. Brass bearings and plastic sleeve bearings are also manufactured for definite applications. A mutual type of bearing sleeves that work well in applications requiring constant lubrication is bronze bearing sleeves, which sometimes contain lubricant plugs (PTFE or graphite) to help with lubrication issues.
Another sleeve material used for light to medium applications, called oil impregnated bronze sleeve bearings, contains pores that absorb oil, which is released under applied force and then reabsorbed back into the bearing once the force subsides.
Advantages and Disadvantages of Sleeve Bearings
More exclusive than ball bearings, sleeve bearings have practically unlimited radial thrust capacity. However, they are suitable for use in moderate to high-speed applications alone. Sleeve bearings offer better stiffness than ball bearings do, and as they have split halves, they are easier to inspect or replace. Worn-out bearing sleeves can be recycled after being rebaited.
