51101

51101 is a commonly used single-direction flat thrust ball bearing in the industrial field, belonging to the basic axial load-bearing bearing of the 51100 series. It adopts a standardized structural design with core product specifications of inner diameter 12mm, outer diameter 26mm and thickness 9mm. The overall structure is compact and small in size, suitable for the lightweight axial installation requirements of various equipment. The core material of the bearing is GCr15 high carbon chromium bearing steel. After precision heat treatment processes such as quenching and tempering, it has excellent hardness, wear resistance, fatigue resistance and dimensional stability, which can effectively resist abrasion and impact during operation and ensure the service life and operation accuracy of the bearing. The bearing is equipped with a steel stamped cage, which is made by an integrated forming process, with high structural strength and accurate positioning. It can stably fix the rolling elements, reduce friction and collision during operation, lower the operating noise and vibration of the equipment, and improve the overall operation smoothness.

In terms of lubrication configuration, the main lubrication method of the 51101 flat thrust ball bearing is lithium-based grease lubrication. Lithium-based grease lubrication has strong adaptability, convenient filling and low maintenance cost. It can form a stable lubricating protective film between the bearing raceway and rolling elements, isolate direct metal contact, effectively reduce the friction coefficient, and has good water and dust resistance, suitable for various conventional industrial working conditions. If the equipment is in special working conditions such as high speed and high temperature, the oil lubrication method can also be replaced according to actual needs to further improve the high-speed adaptability of the bearing. As a pure axial load-bearing bearing, it can only bear single-direction axial load and cannot bear any radial load. In practical application, it can be used with radial bearings such as deep groove ball bearings and cylindrical roller bearings to realize the comprehensive bearing of composite loads. Its rated static load reaches 15.4kN and rated dynamic load is 10.4kN, which can stably meet the requirements of various light and medium axial loads. The limiting speed under grease lubrication condition is 6700r/min. In actual use, the speed can be appropriately adjusted according to installation accuracy, working condition environment and load size, suitable for axial operation scenarios from low-medium speed to medium-high speed.

As a core basic component for lightweight axial support, the 51101 flat thrust ball bearing is widely used in various equipment in many industries by virtue of the advantages of convenient installation and disassembly, high load-bearing efficiency and excellent cost performance. Its core application fields include machine tool equipment (axial support of machine tool spindles, tool rest positioning, feed mechanisms and index plates), general machinery (axial positioning components of small reducers, gear boxes, water pumps and fans), textile machinery (light-load axial operation mechanisms of spinning machines, looms and winders), light industrial machinery (axial transmission components of food packaging machinery, printing machinery and plastic processing equipment), automobile industry (auxiliary axial load-bearing of automobile gearboxes, steering systems and wiper motors), electric tools (motor axial positioning of small electric drills and grinders) and precision instruments (axial support of measuring instruments, small testing equipment and office automation equipment), etc. This bearing is suitable for all transmission mechanisms that require axial positioning, axial load-bearing and zero or negligible radial load. According to the service environment (such as normal temperature, dust, slight humidity), operation speed and load requirements of the equipment, it can be matched with corresponding seals, dust covers and lubrication schemes to further optimize the use stability and environmental adaptability of the bearing and meet the personalized use needs of equipment in different industries.
