• Sleeve bearings are a kind of plain bearing--that is, bearings with few moving parts. Many spherical ball bearings have an internal ring, which is lined with smaller balls inside. In contrast to regular ball bearings, a sleeve bearing only has two moving parts; the outer sleeve and the inner rotating cylinder. They are also known as journal bearings, after the technical term for the outer sleeve. The outer journey of a sleeve bearing may be whole, split, or clenched between the two halves
• Sleeve bearings can be made of compressed powdered metal, such as bronze or copper. Because of the material from which they are made, the metal is microscopically porous. When they are oiled on the outside, the oil will be drawn up through the pores to lubricate the inner cylinder. A sleeve bearing can be lubricated in a number of ways besides oiling. Sometimes, molten metal or graphite is used. Some man-made polymers can lubricate moving parts without seizing up in extremely cold temperatures. Other sleeve bearings are surfaced with porous, oiled hardwood so that the oil will be drawn up into them more readily

Additional information:

• Though they are self-lubricating, sleeve bearings often fail through lack of lubrication. The inner bearing might wear away at the sleeve until the space is no longer perfectly cylindrical. This may cause the bearing to shake when it moves, adversely affecting the movement of the mechanism. Other times, there may not be enough lubricant, or the lubricant may become viscous through adverse temperature conditions. When there is not enough lubrication, the bearing will cease to move. Due to these issues, sleeve bearings are often elaborately shielded from dust and dirt by seals. A designer or mechanic needs to carefully consider where a sleeve bearing will be located in a machine before using it. They are criticized for being more finicky than ball bearings in that inadequate lubricant will cause them to come to a complete stop rather than wear down gradually over time

Split adapter sleeves are used to convert different shaft sizes to ensure compatibility between components. For instance, brass pot adapter sleeves are designed to install knobs that are meant for 1/4" solid shaft pots on split shaft pots, both fine and coarse splined, and metric 6mm solid shaft pots, increasing the diameter of the pot's shaft so the knob will sit centered on the shaft.

Hydraulic adapter sleeves are designed to facilitate the mounting of large bearings using pressurized oil injection systems. These sleeves have oil passages on the threaded side and grooves on the outer surface for oil injection, which is convenient for installation and disassembly of components.

These sleeves are manufactured with high-quality materials to ensure durability and prolong the life of the bearing, protecting it in various industrial applications such as steel construction, cement mining, and textile industries.

Mechanical adapter sleeves are designed to facilitate the mounting of bearings onto shafts using physical force and mechanical principles. These sleeves typically feature a tapered design that allows them to be easily slid onto a cylindrical shaft and secured in place using nuts, bolts, or specialized tools. Key features of mechanical adapter sleeves include simplicity, cost-effectiveness, versatility, and reliable performance.

Tapered adapter sleeves are components used to facilitate the mounting of bearings with a tapered bore onto cylindrical shafts or stepped shafts. They enable easy mounting and dismounting of bearings without requiring additional fixing on the shaft, making them easy to install. These sleeves are commonly used for positioning bearings such as Taper Roller Bearings, Self-Aligning Ball Bearings, Spherical Roller Bearings, and Cylindrical Roller Bearings.

Flanged sleeve bearings are designed for applications where a thrust load or axial constraint is needed, in addition to supporting a radial load. These bearings, also known as sleeve bearings, plastic flanged bushings, or flanged plain bearings, provide high performance and mechanical stability in various applications. They help reduce vibration and noise by using a sliding motion that absorbs friction between moving part.

Wear sleeves are protective covers designed to either protect or cover imperfections on a shaft. They are commonly used in industrial and mechanical applications to extend the life of seals and prevent wear on rotating shafts. Wear sleeves can repair worn surfaces on rotating shafts where oil seals are mounted, restoring the seal's effectiveness without needing to replace the entire shaft.
