Shaft Support Assembly Opposite Side for SICOMA MAO 3000/2000

This kit contains larger dimension parts specific to the MAO 3000/2000 series as follows:

• 1x CRO52 – Main Shaft Bearing (Spherical Roller Type, e.g., 23122 CC)
• 1x MOSA13: – Non-Drive Side Front Flange Cover
• 1x 0529G0006B1: – Vulkandisk (Yellow Elastic Wiper/Damper)
• 1x SCAB-600-230: Blue Intermediate Seal (Dust Ring)
• 1x MOB08: Intermediate Bushing (Shaft Sleeve)
• 1x MOSA14: Protective Bearing Block (Grease Ported)
• 1x MOSAP10: Main Bearing Housing (Support)
• 1x 0228G0008L1: Bearing Outer Cover (Flanged)
• Set: Complete Static O-Ring Set (SCAB-400-239, PA124, PA125, PA126)

• CRO52 – Main Shaft Bearing: This durable spherical roller bearing, often labeled as 23122 CC, handles the intense radial and axial loads on the non-drive side of the MAO 3000/2000 shaft.
• MOSA13 – Non-Drive Side Front Flange Cover: The primary mounting interface that bolts the entire bearing and sealing assembly to the main mixer tank, providing structural rigidity.
• 0529G0006B1 – Vulkandisk (Elastic Disc): This yellow polyurethane ring serves as a dual-purpose component. It acts as a sacrificial wiper, taking the brunt of concrete aggregates before they can reach the main seals.
• SCAB-600-230 – Blue Intermediate Seal: Functioning as the second barrier, this blue polyurethane ring stops fine dust, mud, and slurry from infiltrating the inner primary oil seals.
• MOB08 – Intermediate Bushing (Shaft Sleeve): A hardened, replaceable wear surface fitted over the main shaft. It provides a smooth-running ground for the blue seal, ensuring the expensive main shaft is protected from friction wear.
• MOSA14 – Protective Bearing Block (Grease Ported): A massive structural component that supports the main housing. It contains the critical passages for grease and air purge systems via the pipe inlets, acting as the lubrication hub.
• MOSAP10 – Main Bearing Housing (Support): The primary enclosure that rigidly holds the main bearing and the entire sealing group, mounting directly to the front flange.
• 0228G0008L1 – Bearing Outer Cover (Flanged): The cover that closes the assembly from the outside, axially retaining the bearing and providing the sealing face for a static O-ring.
• Static O-Rings (Set): Various static seals (green and black rings) that seal the fixed, metal-to-metal joints between the bearing housing, covers, and bushings to prevent static leakage.

• Mixer Model: SICOMA MAO 3000/2000 (Heavy-Duty Series)
• Position: Non-Drive Side (Opposite Motor Side)
• Operation: Complete Bearing & Housing Group Overhaul
• Compatibility: Strictly for Non-Drive side (Not for Motor Side)

This kit is a critical item in our Sicoma Twin Shaft Concrete Mixer Spare Parts inventory.

• Exclusive Fitment: It is designed exclusively for the Non-Drive Side of the MAO 3000/2000. It is not compatible with the Drive-Side or smaller mixer models (e.g., MAO 1500).
• Recommendation: Cross-checking against the mixer serial number in the Sicoma spare parts catalogue is mandatory for correct part identification.

• Procedure: This is a complete rebuild. All old components—every seal, ring, bearing, and housing—must be removed and surfaces cleaned.
• Bearing Fit: The CRO52 is a precision component; it must be installed with a press or induction heater. Direct hammer impacts will destroy it.
• Lubrication: Apply a light film of clean grease on all new rubber/elastic seals (Vulkandisk, Blue Seal) before assembly to prevent dry-start damage.
• For critical maintenance, installation should be performed by a qualified technician.

• If the product is not in stock, it is delivered to order, usually within 4-6 weeks after making an advance payment.
• Some items may be in transit, so checking the delivery time before ordering is recommended.
