LD-M6F-3N1D-00 Heavy-Duty Piston Motor | 57209637 Mining Domestic Replacement & Russia Export Hydraulic Motor

1. Product Overview

HYDSUNRIDA is a professional manufacturer specialized in the R&D and mass production of mining hydraulic motors, providing high-quality domestic replacement solutions and standardized overseas export hydraulic parts. The LD-M6F-3N1D-00 heavy-duty axial piston motor (OEM Part No. 57209637) is our star model for heavy mining equipment renewal and Russian market export.This motor achieves 1:1 non-destructive interchangeability with original imported units, with fully consistent installation size, shaft diameter, oil port layout and working parameters. No equipment refitting or pipeline adjustment is required, enabling direct plug-and-play replacement for Epiroc and Atlas Copco mining machinery maintenance and localized upgrading. Certified by ISO9001 quality system and SGS performance verification, every motor undergoes multiple strict factory tests. It features stable rotation, large torque output, ultra-low internal leakage, excellent low-temperature resistance and long service life. Optimized for extreme cold and harsh mining working conditions, this in-stock model has been steadily exported to more than 30 countries worldwide with reliable market reputation.

2. Full Product Model Range

To meet the differentiated demands of domestic engineering supporting and overseas foreign trade projects, we have launched two complete series with unified specifications, ensuring zero interchange error and high matching accuracy:Domestic General Models: LD-M6F-3N1D-00 (Core replacement model for 57209637), LD-M6F-2N1D-00, LD-M6F-4N1D-00Overseas Export Models (Russia & Europe Exclusive): LD-M6F-3N1D-EX, LD-M6F-2N1D-EX, LD-M6F-4N1D-EX

3. Core Technical Parameters

Standardized structural and performance parameters ensure stable operation and perfect interchangeability:

4. Product Core Advantages

4.1 Fully Self-developed & Self-produced, Stable Consistent Quality

All core friction components are independently processed and produced in our own factory. Adopting automated dust-free assembly and professional laboratory testing procedures without outsourcing or OEM labeling, this motor fundamentally eliminates common faults such as oil leakage, overheating, abnormal noise and premature wear, ensuring excellent consistency and long-term stable heavy-load operation.

4.2 1:1 Non-destructive Replacement, Cost & Efficiency Optimization

Fully matched with imported motors in installation dimensions and power parameters, it is widely compatible with full-range Epiroc and Atlas Copco mining equipment. Zero-modification replacement effectively shortens equipment downtime and greatly reduces daily maintenance and equipment upgrading costs.

4.3 Strict Quality Control, Wide Working Condition Adaptability

Supported by dual ISO and SGS certifications, every unit completes full inspection including high-pressure impact test, long-duration endurance test, sealing performance test and parameter calibration. It reliably copes with harsh mining environments featuring heavy dust, frequent impact and overload continuous operation, achieving low failure rate and prolonged service life.

4.4 In-stock Direct Delivery, High Comprehensive Cost Performance

As a direct manufacturer, we supply products to end customers without intermediate markup. Full series are sufficiently in stock for 48-hour rapid shipment. Bulk purchasers can enjoy tiered discounts and long-term price protection agreements. Compared with imported hydraulic parts, our motors feature lower procurement cost, faster delivery and more responsive after-sales service.

4.5 Customized Solutions for Special Working Scenarios

We support OEM branding and ODM customized hydraulic system development. Structural configurations can be optimized for extreme cold, heavy-load and high-dust working conditions. One-stop supporting services including hydraulic pumps, valve blocks and power units are available to meet customized demands for domestic renovation and overseas non-standard projects.

4.6 Russia-targeted Optimization & Mature Global Export System

Specially optimized for Russia’s ultra-low temperature and round-the-clock field heavy-duty operation, this motor delivers outstanding cold resistance, wear resistance and reliable low-temperature startup performance. It has achieved long-term stable bulk supply for Russian mining and infrastructure projects with high repurchase rates. Complete export qualification documents support compliant sales to more than 30 countries worldwide.

5. Compatible Mainstream Mining Equipment

As a high-cost-performance domestic alternative to imported hydraulic parts, this piston motor is perfectly applicable to the following mainstream mining equipment:

5.1 Epiroc Tunnel Drilling Jumbos

Compatible with BOOMER 281, 353, S1D, L1D models. It can replace rotary motors, auxiliary drive motors and cooling fan motors, adapting to high-frequency and heavy-load tunneling working conditions.

5.2 Epiroc Open-pit Drilling Rigs

Compatible with ROC D60, D65, FlexiROC T40 R, PowerROC T35/T40 open-pit top hammer drilling rigs. It realizes non-destructive replacement of original hydraulic units and withstands 24-hour uninterrupted continuous operation.

5.3 Epiroc Geological Exploration Drilling Rigs

Compatible with Boyles C6C core drilling rigs, geological sampling and pile foundation drilling equipment. With sufficient torque, strong impact resistance and excellent wear resistance, it adapts to complex and changeable field geological operation scenarios.
