Mixer Truck Bearing Cover with ≤0.019mm Tolerance and Ra ≤1.6μm Surface Finish for Drive Shafts

A precision-engineered protective component for mixer truck transmission systems, designed to secure and shield bearings on rotating parts including mixing tank drive shafts, support wheel axles, and reducer output shafts. Ensures operational reliability, extends bearing life, and reduces maintenance costs through superior sealing and mechanical fixation.

• Precision Machining: Dimensional tolerance ≤0.019mm for perfect fit
• Ultra-Smooth Surface: Surface roughness Ra ≤1.6μm to minimize friction
• Robust Material: 45 steel construction for high strength and durability
• Multi-Function Design: Integrates mechanical fixation, sealing, load transmission, and maintenance access

• Mechanical Fixation: Locks bearings in position securely
• Sealing Protection: Prevents contaminant ingress and extends bearing life
• Load Transmission: Distributes operational stresses evenly
• Maintenance Friendly: Enables quick service access for reduced downtime

• Ensures precise rotation of mixing tank components
• Extends bearing service life by ≥30%
• Reduces operational downtime and maintenance costs
