LR5200

LR5200 is a professional-grade double-row track roller bearing specially designed for heavy-duty rolling working conditions. It adopts an integrated formed double-row rolling element structure with core product specifications: inner diameter 10mm, outer diameter 32mm and width 14mm. The overall structure is compact with excellent rigidity, which can bear heavy loads in a limited installation space, and has a low rolling friction coefficient, suitable for rolling support mechanisms of various equipment. It is easy to install and disassemble, and can be directly matched with the shaft diameter and mounting surface, greatly improving the assembly efficiency of equipment.

The core components of the bearing are all forged and processed with GCr15 high carbon chromium bearing steel. After professional heat treatment processes such as quenching and low-temperature tempering, the surface hardness of the raceways and rolling elements reaches HRC60-64, with excellent wear resistance, fatigue resistance and impact resistance. It can effectively resist abrasion, crushing and micro-impact damage under heavy-duty working conditions, ensuring the structural stability and service life of the bearing during long-term continuous operation. The bearing is equipped with a high-precision stamped steel cage, with rolling elements evenly distributed in double rows, which can effectively disperse loads, avoid local stress concentration, reduce friction and collision between rolling elements at the same time, lower operating noise and improve the smoothness of bearing operation.

In terms of lubrication configuration, the LR5200 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 working conditions of -20℃ to 120℃. After filling, it can form a high-strength lubricating protective film between the raceway and rolling elements, isolate direct metal contact, 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 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 and much water, the grease can be supplemented or replaced with special high-temperature/waterproof lithium-based grease as needed to further improve the environmental adaptability of the bearing.

As a heavy-duty track roller bearing, LR5200 focuses on heavy radial load bearing capacity, and can bear both heavy radial load and slight bidirectional axial load at the same time, adapting to various heavy-duty rolling support scenarios. Its rated static load reaches 22.4kN and rated dynamic load is 15.2kN, which can stably cope with various load forms such as continuous heavy load and intermittent impact load, meeting the bearing requirements of heavy-duty equipment. The limiting speed of the bearing under grease lubrication condition is 6000r/min, and the actual service speed can be flexibly adjusted according to the equipment installation accuracy, load size and working condition environment, suitable for medium and low speed heavy-duty rolling operation scenarios, and is a core supporting component of rolling support for various heavy-duty equipment.

With the core advantages of heavy load bearing, excellent structural rigidity, strong wear resistance and wide adaptability, the LR5200 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), the automation equipment industry (traveling rollers of industrial robots and precision manipulators, rolling support of tooling fixtures in automatic production lines), the engineering machinery industry (traveling mechanisms of small excavators and loaders, lifting/translation rollers of construction machinery), the metallurgical machinery industry (rolling support components of metallurgical conveying roller tables and steel rolling auxiliary machinery), the light industrial machinery industry (rollers of paper feeding/material feeding mechanisms of large printing machinery and packaging 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 textile machinery, and is a commonly used basic component for heavy-duty rolling support in industrial production. According to the actual working condition requirements of the equipment, it can be matched with protective accessories such as dust covers and sealing rings to further optimize the sealing and protective performance of the bearing and improve the use stability.
