SIMEM MSO Mixer – Shaft End Bearing & Seal Kit

This comprehensive OEM-compatible service kit is designed for the SIMEM MSO series twin-shaft concrete mixers, supporting scheduled maintenance or complete shaft-end overhauls. Each component is precision-manufactured to meet SIMEM performance standards, ensuring reliability, longevity, and ease of installation.

🔧 KIT CONTENTS

🧱 Bearing & Shaft Support Components

• Spherical Roller Bearings (x2):
  Self-aligning, high-load capacity bearings for radial and axial loads — engineered for the demanding operating environment of the mixer shaft ends.

• Adapter Sleeves with Locking Assemblies (x2):
  Tapered adapter sleeves with integrated locking nuts and tab washers for secure positioning of the bearings on the shaft.

• Bearing Housing Units (Split Type, x2):
  Cast-iron pedestal housings, precision-machined and split for ease of maintenance. Includes cap bolts and lubrication points.

• Shaft Protection Sleeves (x2):
  Hardened steel sleeves to reduce wear on the main shaft journal areas, optimizing bearing interface.

🔒 Sealing & Contamination Control

• Split Shaft Seals – Rubber (x4):
  Flexible sealing elements designed for easy retrofit without shaft disassembly, resistant to abrasion and concrete ingress.

• Labyrinth Seal Assemblies (x2):
  Multi-stage metal labyrinths for non-contact sealing of the bearing chamber, extending lubrication life and minimizing contamination.

• Polyurethane Rotary Seals (x2):
  High-performance dynamic seals with excellent chemical and wear resistance, designed to complement the labyrinth arrangement.

• Seal Carriers & Retaining Rings (x2 sets):
  Machined carriers and internal support rings for precise alignment and stable seal positioning during high-speed operation.

🔩 Hardware & Fasteners

• Complete Fastener Set:
  High-tensile hex bolts, lock nuts, and spring washers for housing assembly and seal retention — zinc-plated for corrosion resistance.

• Bearing End Flanges (x2):
  Precision flanges for sealing integration and axial load distribution at the housing interfaces.

🔄 Applications

This kit is intended for use during:

• Planned maintenance intervals (e.g. every 3,000–5,000 operating hours)

• Shaft-end overhauls

• Emergency bearing replacements
