Product Description Long Type Large Roller Full Bore 6 Needle Bearing with Inner Ring 8 10 12 20 Needle Roller HK0306 1210 Full Pin Swelling BearingProduct DescriptionNeedle bearings are a type of roller bearing that use long, thin cylindrical rollers instead of balls to reduce friction and support radial loads. The rollers are typically slightly longer than their diameter, giving them a high length-to-diameter ratio that allows them to support high radial loads in a small space.Needle bearings are commonly used in various industrial and mechanical applications, such as automotive transmissions, engines, and steering systems, as well as in agricultural machinery, construction equipment, and other heavy-duty applications.One advantage of needle bearings is their ability to support high radial loads with relatively low friction, reducing wear and extending the path's and surrounding components' lifespan. They can also operate at high speeds and in various temperatures and operating conditions.Properly selecting and installing needle bearings is essential to ensure their efficient operation and optimal performance. Careful consideration should be given to the application's specific requirements, such as the load capacity, operating speed, and temperature range.Regular inspection and maintenance of the needle bearings is also essential to ensure their longevity and efficiency. The bearings should be regularly inspected for wear and damage, and the lubrication should be checked and replenished according to the manufacturer's recommendations to ensure smooth and reliable operation.In addition, the bearings should be properly installed and aligned with the shaft and housing to prevent excessive wear and damage, and the load distribution should be optimized to avoid overloading or uneven wear.Needle Roller Bearing ApplicationsAutomotive Industry:Transmissions: Both manual and automatic transmissions make extensive use of needle roller bearings because of their high load-carrying capacity in a small space.Connecting rods: In internal combustion engines, they support the crankshaft and piston pin.Pumps (e.g., water pumps, oil pumps, air conditioning compressors): Used where compact, efficient and durable operation is required.Drive shafts and universal joints: Provide stable support in the drive train.Rocker arm pivots: Used in engine valve trains.Steering systems: Used to achieve smooth and precise movement.Agricultural machinery:Transmissions: In various agricultural implements such as rotary tillers, mowers, balers and harvesters, compact gear arrangements transmit power under heavy loads.PTO (power take-off) drives: Used in certain joints or support areas.Conveying systems: Components used to handle crop materials.Construction and heavy equipment:Excavators, loaders, bulldozers: used in gearboxes, hydraulic pumps and rollers that are often subjected to high loads and harsh conditions.Cranes and lifts: used in various pulley systems and drive mechanisms.Power tools:Drills, saws, grinders: able to withstand high rotation speeds and shock loads due to their compact size.Chain saws: used in drive mechanisms.Industrial machinery:Pumps and compressors: used for efficient and durable rotation.Textile machinery: used for various rotating parts that require precision and compactness.Printing presses: used for smooth and accurate roller movement.Conveyor rollers: used in certain high-load conveying systems.Other professional applications:Bicycles: used in pedals and hubs for efficiency and durability.Office equipment: used for certain parts that require smooth movement in a small space.
