Needle Bearings 1)Competive price 2)Prompt delivery 3)Small orders accept 4Good service Needle Bearings Needle bearings are roller bearings with rollers that have high length-to diameter ratios. Needle bearings are used in farm and construction equipment, automotive transmissions, small gasoline engines, gear pumps, small appliance and tool motors, alternators, and aircraft controls. Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty needle bearings never require relubrication, but high loads or speeds demand it. Compared with other roller bearings, needle bearings have much smaller rollers for a given bore size. Needle bearings have the highest load capacity for a given radial space of all rolling-element bearings, but their use is limited to bore diameters less than 10 in. All needle bearings are variations of two basic designs. The first needle bearing design, full complement, has a full complement of needles and contains no retainer. The second needle bearing design, caged needle, contains a retainer or cage for roller guidance and spacing. Caged needle bearings have smaller roller complements and lower load capacities than full-complement bearings. Needle bearings have the advantage of a higher speed capacity; retainers prevent high-velocity rubbing between adjacent needles and provide more effective roller guidance. Needle bearings also have greater lubricant capacity. Needle Bearings Cross-section is small, but very high load capacity, so it is suitable for radial bearing configuration space is limited. Needle roller bearings have a low sectional height and high load capacity. General purpose needle type bearings to maintain a high speed bearing performance under its outstanding, needle roller shape by a special high rigidity and precision of the cage proper guidance, size error is very low. Particularly suitable for use in a small space also because they have very high lubricant capacity, light weight and high stiffness characteristics, can in severe cases, use: such as high speed, shock load and other circumstances, the use of a wide range History Our company was emerged in last century, we have more than 10 years of experience in this line.
