Function Features of R911317019 Spare Part Kit

1. Integrated All-In-One Maintenance Kit Design

   A single part number contains all commonly replaced wear components for MSK040 and MSK070 servo motors during routine maintenance and fault repair. Maintenance personnel only need to order this one part number to complete full motor sealing system overhaul, eliminating tedious separate ordering of multiple scattered small spare parts and simplifying factory spare part inventory management.

2. 100% Original Rexroth OEM Standard Components

   Every component inside the R911317019 kit is manufactured on the same production line as the original components installed on brand-new MSK series servo motors. All dimensional tolerances, material formulations, and surface processing standards fully match factory original specifications, ensuring perfect mechanical interchangeability without machining, modification, or fitting adjustment during on-site replacement installation.

3. Universal Dual Frame Size Compatibility

   The spare part kit supports both MSK040 small frame and MSK070 medium frame servo motors, covering the two most widely used mid-range IndraDyn S servo motor models in industrial automation equipment. Factories using mixed MSK040 and MSK070 motor equipment only need to stock this single spare part kit to cover all routine sealing system maintenance demands for both motor frame sizes.

4. Complete Sealing System Overhaul Support

   All critical motor environmental sealing wear components are fully included within the kit, enabling full disassembly and replacement of the entire motor sealing assembly during overhaul maintenance. After full sealing component replacement, the motor recovers factory original IP65 dust and splash protection performance, eliminating liquid leakage and dust penetration faults caused by aged, worn original sealing parts.

5. Pre-Packaged Sealing Assembly Lubrication Grease

   High-performance anti-corrosion silicone sealing grease is pre-included inside the kit. The grease is specially formulated for fluorine rubber FKM sealing components, providing long-term lubrication to reduce shaft seal friction wear during motor rotation, prevent O-ring cracking and hardening caused by high temperature aging, and improve sealing surface fitting tightness to eliminate fluid leakage.

Application Scenarios for R911317019 Spare Part Kit

• Routine scheduled overhaul maintenance of MSK040 / MSK070 Rexroth servo motors on production line automation equipment
• Fault repair of servo motors with shaft oil seal leakage, encoder housing O-ring liquid seepage, dust contamination of internal motor components
• Equipment spare part inventory stock preparation for manufacturing factories equipped with Rexroth MSK series servo motor drive axes
• After-sales maintenance service kit for Rexroth authorized industrial automation equipment repair service providers
• Long-term idle servo motor restoration maintenance before equipment restart production operation

Material & Structural Characteristics of Kit Components

1. Shaft Lip Oil Seal

   Main sealing body made of high-hardness FKM fluorine rubber with integrated stainless steel reinforcing inner metal skeleton. The lip contact surface is precision molded with micro-lubrication storage grooves to maintain continuous thin oil film between seal lip and motor output shaft during rotation, minimizing friction wear and preventing hydraulic oil, cutting fluid leakage from the motor front shaft end.

2. Encoder Housing O-Ring Seals

   Solid circular ring components molded from FKM fluorine rubber with uniform cross-sectional diameter. The material maintains stable elastic compression performance under wide temperature fluctuation ranges, resisting aging hardening caused by oil mist and high-temperature workshop environments, maintaining complete sealing between the encoder rear cover and motor stator housing to block dust and liquid contaminants.

3. Bearing Dust-Proof Gaskets

   Thin flat circular gaskets manufactured from oil-resistant nitrile rubber with integrated metal outer ring reinforcement. Installed between motor bearing end caps and stator housing inner cavities, forming a secondary dust isolation barrier to prevent fine metal cutting dust particles from penetrating into the bearing assembly and causing bearing abrasion and noise faults.

4. Encoder Plug Contact Pin Assembly

   Precision stamped copper alloy contact pins with full-surface thick gold plating anti-oxidation treatment. Gold plating eliminates contact resistance drift caused by long-term plugging abrasion and air oxidation, maintaining stable differential Hiperface encoder signal transmission without intermittent signal loss or position feedback distortion faults.

5. Cable Strain Relief Connector Sleeves

   High-flexibility reinforced PA66 glass fiber filled engineering plastic injection molded sleeves. High tensile strength and strong anti-fatigue performance prevent cable bending fatigue fracture at the motor power and encoder plug ports, absorbing cable pulling force to avoid plug internal contact pin loosening and signal interruption faults.

6. Sealing Silicone Lubrication Grease

   Transparent food-grade anti-corrosion silicone grease, chemically inert with FKM fluorine rubber materials, no swelling or chemical degradation effect on rubber sealing components. Wide temperature operating range, stable lubrication performance at low and high ambient temperatures, forming a permanent protective lubrication film on all sealing component contact surfaces after assembly.
