LR5202

LR5202 is a double-row track roller bearing specially designed for industrial heavy-duty rolling working conditions, adopting an integrated double-row rolling element structural design with core product specifications: inner diameter 15mm, outer diameter 40mm and width 15.9mm. The overall structure is compact with outstanding rigidity, which can bear heavy radial loads in a narrow installation space and has a low rolling friction coefficient, suitable for rolling support mechanisms of various equipment. It can be directly matched with the corresponding shaft diameter and mounting surface during installation without complex tooling, greatly improving the assembly and later maintenance efficiency of the equipment.

The core components of the bearing are all processed by forging with GCr15 high carbon chromium bearing steel. After precision turning and grinding, the blank is treated by professional heat treatment processes such as quenching and low-temperature tempering, so that the surface hardness of the bearing raceways and rolling elements reaches HRC60-64, and the internal metallographic structure is uniform and stable. It has excellent wear resistance, fatigue resistance and impact resistance, can effectively resist abrasion, crushing and intermittent micro-impact damage under heavy-duty working conditions, ensure the structural stability and service life of the bearing during long-term continuous operation, and meet the continuous operation requirements of heavy-duty equipment. The bearing is equipped with a high-precision stamped steel cage with double rows of rolling elements evenly distributed, which can effectively disperse loads, avoid local stress concentration, reduce friction, collision and jamming between rolling elements, lower the noise and vibration of equipment operation, and further improve the smoothness of bearing operation.

In terms of lubrication configuration, the LR5202 track roller bearing adopts lithium-based grease lubrication as the standard configuration, equipped with special lithium-based grease for heavy-duty bearings as standard. The grease has excellent adhesion, extreme pressure resistance and high and low temperature adaptability, and can be used stably under conventional industrial working conditions of -20℃ to 120℃. After filling, it can form a high-strength, dense lubricating protective film between the raceway and rolling elements, completely isolate the direct friction of metal contact surfaces, greatly reduce the friction coefficient under heavy-duty rolling and reduce component wear. In addition, the grease has good sealing retention, is not easy to lose under heavy-duty and low-speed working conditions, and has a long maintenance cycle, which can effectively control the daily maintenance cost of equipment. If the equipment is in special working conditions such as high temperature, much dust, much water and slight corrosion, the grease can be supplemented or replaced with special high-temperature and waterproof lithium-based grease as needed, and protective accessories such as dust covers and sealing rings can be matched at the same time to further improve the environmental adaptability and use stability of the bearing.

As a professional heavy-duty track roller bearing, LR5202 features super strong radial load bearing capacity, and can bear both heavy radial load and slight bidirectional axial load at the same time, adapting to various industrial heavy-duty rolling support scenarios. Its rated static load reaches 31.5kN and rated dynamic load is 21.2kN, which can stably cope with various load forms such as continuous heavy load and intermittent impact load, fully meeting the bearing requirements of heavy-duty equipment in metallurgy, logistics, engineering machinery and other industries. Under the conventional working condition of grease lubrication, the limiting speed of the bearing is 5000r/min, and the actual service speed can be flexibly adjusted according to the installation accuracy, load size and working condition environment of the equipment, which is generally suitable for medium and low speed heavy-duty rolling operation scenarios, and is a core basic component for rolling support of various industrial heavy-duty equipment.

With the core advantages of strong heavy-duty bearing capacity, excellent structural rigidity, outstanding wear resistance and wide adaptability, the LR5202 double-row track roller bearing is widely used in heavy-duty equipment in many industries. Its core application fields include the logistics conveying equipment industry (roller support of belt conveyors, roller conveyors and automatic sorting lines, traveling mechanism of automated storage and retrieval system stackers, shelf rollers), the automation equipment industry (traveling rollers of industrial robots and precision manipulators, rolling support of tooling fixtures in automatic production lines, guide rail rolling components of CNC equipment), the engineering machinery industry (traveling mechanisms of small excavators, loaders and forklifts, lifting and translation roller support of construction machinery), the metallurgical machinery industry (rolling support components of metallurgical conveying roller tables, steel rolling auxiliary machinery and metallurgical silos), the light industrial machinery industry (rollers of paper feeding and material feeding mechanisms of large printing machinery, packaging machinery and textile machinery) and the mining machinery industry (rolling support of small mining conveying equipment and mineral processing equipment), etc. At the same time, it can also be adapted to heavy-duty rolling mechanisms of various heavy machine tools and port machinery, and is a commonly used component for heavy-duty rolling support in industrial production. According to the actual working condition requirements of the equipment, different styles such as open type, 2RS double-sided rubber seal and NPPU nylon cage seal can be flexibly selected to meet the use requirements of different scenarios.
