Product Description
Product Overview
This product is a large-specification Q430 hole elastic retaining ring compliant with GB/T 893.1 standard, with an applicable hole diameter of 430mm. Manufactured from high-quality 65Mn spring steel, its surface is treated with an environmentally friendly Dacromet process. The product has extremely high elastic limit and fatigue strength, specially designed for the positioning of large bearing holes in heavy-duty equipment, providing reliable axial fixation and long-term corrosion protection.
Core Advantages
-
Large-Specification Load-Bearing: The 430mm large-diameter design provides reliable axial positioning for large bearings of heavy-duty equipment.
-
Excellent Elastic Performance: 65Mn spring steel ensures the retaining ring has long-lasting elasticity and fatigue resistance, making it durable.
-
Top-Level Corrosion Protection: The Dacromet coating has excellent corrosion resistance, and its salt spray resistance time is far longer than that of ordinary electroplating processes.
-
Precise Dimensional Control: Strictly manufactured in accordance with national standards to ensure perfect fit with the base hole groove.
Applicable Industries
-
Heavy-Duty and Mining Machinery: Axial positioning and fixation of slewing bearings and transmission shafts of heavy-duty equipment such as large mining crushers, ball mills, and port cranes.
-
Wind Power and New Energy Equipment: Precision bearing positioning of large slewing components such as wind turbine main shafts, gearboxes, yaw and pitch systems.
-
Rail Transit and Vehicle Engineering: Axial fixation of bearings in axle bearing boxes and traction transmission system gearboxes of railway locomotives, freight cars and urban rail vehicles.
-
Metallurgical and Chemical Equipment: Axial limiting of rotating components in high-temperature and high-load environments such as large steel rolling equipment, rotary kilns, heavy compressors and pumps/valves.
-
Construction Machinery and Heavy-Duty Vehicles: Bearing positioning of large assemblies such as large excavators, crawler crane slewing bearings, heavy-duty truck hubs and gearboxes.
-
Large-Scale Conveying and Material Handling: Bearing fixation of key parts such as stackers and reclaimers, large belt conveyor drum shafts, and heavy-duty reducers.
-
Hydropower and Heavy-Duty Power Equipment: Axial positioning and protection of bearings in large precision transmission systems such as hydropower generating units and large industrial gearboxes.
Warm Tips
-
Please use special hole circlip pliers during installation to ensure the retaining ring is fully inserted into the installation groove.
-
Do not over-expand the retaining ring to avoid exceeding its elastic limit and causing permanent deformation.
