Needle Bearings: Its Designs and Applications by Rich M.

This article will help you learn about the basic used and designs as well as the different industrial applications of needle bearings.

Needle bearings are also known as needle roller bearings. They are bearings that contain small cylindrical rollers. They are important in order to lessen friction while a certain surface is being rotated. When compared to ball bearings, they cover larger surface areas. The structure has a shaft or an inner race, a needle cage, needle rollers and the outer race. The needle cage is where the needle rollers are contained and oriented.

There are actually different designs and applications for needle bearings. The design actually depends upon the industry where the tool will be needed. Below, you will see what these designs are and where the industrial product is being applied.

Basic designs for needle roller bearings

There are two basic designs for needle roller bearings: one is the full complement or loose-needle; and the other is the caged-needle bearing designs. The loose needles are those that contain full complement needles with no retainers. They are often found in between components of two hardened machines. These are inexpensive but only have moderate speeds and can often lead to misalignment sensitivities.

Caged needles on the other hand contain cages with specific roller spacing and guidance. When compared with loose-needles, they are three times faster. The needle cage allows for prevention of high-velocity rubbing in between needles that are adjacent to each other plus it also provides better roller guidance. They also produce better lubricant capabilities. With the smaller needles complementing each other, load capacity is reduced.

Other designs for needle roller bearings

Alongside the two basic designs are different subcategories. With loose needles, drawn cups are also produced. Drawn cups may also be applicable in caged assemblies. For heavy-duty needle roller bearings, aircraft bearings and cam or track followers are also designed.

Drawn cups for loose needles have spherical-ended rollers with an outer race. This adds up slightly on load capacity for the machine. The caged-needle version differs in the sense that retainers are being used. These provide higher speed with a reduced load capacity. It promises greater tolerance in cases of misalignment.

As the name implies, heavy-duty needle bearings are made out of heavy-duty materials. Heavy outer rings work well with high-precision ground and hardened materials. The load capacity for this design is extremely high.

Needle roller bearing applications

Needle bearings are often used in farm equipment, construction tools and machinery, small gasoline engines and gear pumps. It is also especially helpful in automotive transmissions, aircraft controls, small appliance and tool motors. Hydraulic pumps, sheave blocks, hoist drum shaft, material handling equipment are also included on the list of needle roller bearing applications.
