Jiangsu Manqi Machinery Co., Ltd., a professional manufacturer based in Suzhou, Jiangsu, China, is proud to introduce the Oil Leak Proof DCY355 Bevel Cylindrical Gear Reducer, specifically engineered for stone powder production lines. Our gear reducer combines robust construction with advanced sealing technology to effectively prevent oil leakage, ensuring reliable operation even in harsh industrial environments. With over 5 years of manufacturing excellence since 2017, we deliver high-quality solutions that enhance your production efficiency and reduce maintenance downtime.
The DCY355 model features a bevel-cylindrical gear train designed to handle heavy loads and high torque demands typical in stone powder processing. Its oil-leak-proof design utilizes multi-lip seals and precision machined housings, making it ideal for continuous operation where cleanliness and sustainability matter. This gear reducer is a cost-effective alternative to imported brands, offering equivalent performance at a competitive price.
Key Features & Technical Specifications
Oil Leak Proof Design: Patented seal system with double oil seals and labyrinth grooves, tested for zero leakage under continuous operation.
High Torque Capacity: Bevel gear stage followed by cylindrical gears provide smooth power transmission with efficiency up to 96%.
Durable Materials: Gears made of 20CrMnTi alloy steel with carburizing and quenching treatment (surface hardness HRC 58-62), ensuring long service life.
Compact Structure: Integrated housing design reduces footprint, suitable for limited installation spaces in stone powder plants.
Easy Maintenance: The oil drain plug and oil level indicator allow quick oil changes without disassembling the reducer.
Customizable Options: Available with different input/output shaft configurations, flange mounting, and backstop device upon request.

Benefits for Stone Powder Production
Minimized Production Interruptions: The oil-leak-proof feature prevents contamination of stone powder material and reduces the need for frequent cleaning.
Reduced Operating Costs: Lower maintenance frequency and longer gear life mean fewer spare parts replacements.
Energy Efficiency: High transmission efficiency reduces electricity consumption, which is crucial for large-scale production lines.
Quiet Operation: Precision-ground gears and optimized tooth profile result in noise levels below 75 dB under normal load.

Frequently Asked Questions (FAQ)
-
Q: What makes the DCY355 oil leak proof compared to ordinary gear reducers?
A: The DCY355 features a dual-seal system with high-quality nitrile rubber oil seals and a labyrinth seal in the housing, which effectively prevents oil leakage even at high speeds or in tilted installation positions. Additional seal grooves and precision-machined surfaces ensure zero leakage for extended periods.
-
Q: Can this reducer be used for other applications besides stone powder production?
A: While it is optimized for stone powder lines due to its robust sealing and dust resistance, the DCY355 can also be used in cement, mining, fertilizer, and other heavy industries where high torque and reliable sealing are required. Please consult our sales team for specific application needs.
-
Q: What is the expected service life of the DCY355 gear reducer?
A: Under proper lubrication and maintenance, the DCY355 typically operates for over 20,000 hours before major overhaul. The gears are designed with a safety factor of 1.5, and bearings are selected for high radial and axial loads.
-
Q: Do you provide customized input/output shaft sizes or mounting flanges?
A: Yes, we offer customization options including shaft diameter, keyway dimensions, flange orientation, and backstop devices. Please provide your equipment drawings or specifications for a tailored solution. Lead time for custom orders is 15–20 working days.
-
Q: What type of oil should be used in this reducer?
A: We recommend using mineral-based gear oil ISO VG 320 or synthetic oil VG 460 for extreme temperature conditions. Initially, fill to the oil level indicator mark. Oil should be changed after the first 500 hours of operation, and then every 3,000–4,000 hours thereafter.
-
Q: How is the product packaged for shipment?
A: Each reducer is packed in a wooden crate lined with foam to prevent movement. All openings are sealed with plastic caps, and rust inhibitor oil is applied to exposed shafts. We can also provide export-worthy fumigated wooden crates upon request.
-
Q: What is the warranty period and after-sales service?
A: We offer a 12-month warranty from the date of shipment, covering manufacturing defects. Technical support is available via email or phone during business hours. For complex issues, we can arrange video inspection or send a representative if within Southeast Asia.
-
Q: Can I visit your factory in Suzhou?
A: Absolutely. We welcome customers from all over the world to tour our plant. Please contact us in advance to schedule an appointment. We are located near Suzhou Industrial Park, about 1 hour from Shanghai.
