Sleeve bearings are highly resistant to wear, dirt, and dust. Sleeve bearings are also easier to install than other types of bearings. A sleeve bearing can be made of bronze or even plastic. Like sleeve bearings, a plain bearing uses a sliding, rather than a rolling motion to carry heavy loads. A spherical bearing performs a similar function as well. Zoro also has a super selection of plain bearings, sleeve bearings, metric sleeve bearings, and spherical plain bearings.
