Concrete Mixer Bearings

For Heavy-Duty, Shock Load, and Contamination Conditions

Concrete Mixer Bearings are special bearings designed for high load capacity, shock resistance, contamination resistance, and long service life. Most of them are customized designs such as 40779 and 800730.
They are designed to support both radial and axial loads, often with double-row structures. Equipped with oil seals to prevent water, cement slurry, and dust contamination, they support continuous rotation of the mixing drum, reduce friction and energy consumption, ensure stable and smooth operation, extend equipment service life, and reduce maintenance.
BKZ Industry, as a concrete mixer bearing manufacturer and factory, can provide various types of bearings for concrete mixers, such as Double Row Angular Contact Ball Bearings, Spherical Roller Bearings, and Cylindrical Roller Bearings, etc., with ISO 9001 certification and 15 years of manufacturing experience.

Bearing Challenges in Concrete Mixer Trucks

Concrete mixer truck bearing​s operate under heavy loads, contamination, and continuous rotation, leading to increased wear, lubrication challenges, and reduced service life if not properly designed and maintained.

Abrasive Particles Entering Concrete Mixer Bearings

Abrasive particles entering the bearing cause surface damage, reducing performance and shortening service life.

Frequent Start Stop For Concrete Mixer Bearings

Frequent start-stop operations accelerate wear, causing surface fatigue and reduced bearing durability.

Uneven Loads And Continuous Vibration For Concrete Mixer Bearings

Uneven loads and continuous vibration cause fatigue damage, leading to premature bearing failure.

Water Cement Slurry And Dust Contamination Concrete Mixer Bearings

Water, cement slurry, and dust contamination accelerate wear, resulting in lubrication failure and corrosion.

High Combined Radial And Axial Loads Concrete Mixer Bearings

High combined radial and axial loads create stress concentration, leading to deformation and early damage.

Misalignment And Improper Installation For Concrete Mixer Bearings

Misalignment and improper installation cause uneven load distribution, resulting in vibration and premature failure.

Continuous Rotation Of The Mixing Drum Concrete Mixer Bearings

Continuous rotation of the mixing drum generates heat, reducing lubrication performance and service life.

Lubrication Difficulties In Harsh Environments

Lubrication difficulties in harsh environments lead to insufficient lubrication, increasing wear and overheating.

Why Choose BKZ Industry Concrete Mixer Bearings?

To withstand harsh operating conditions in concrete mixer trucks, BKZ Industry develops high-performance bearings with advanced sealing, optimized internal geometry, and specialized heat treatment to ensure durability and long service life.

High Performance Sealing Solutions For Forklift Bearings

High-performance Seals and Oil Seals

High-performance multi-lip seals with NBR or FKM materials, combined with labyrinth structures, effectively prevent ingress of water, cement slurry, and dust. Designed to resist abrasion, chemicals, and temperature variations while minimizing grease leakage under vibration.

Reinforced Raceway And Rolling Element Design

Reinforced Raceway and Rolling Element Design

Optimized raceway geometry with crowned profiles and logarithmic modifications improves load distribution. Through-hardened or case-hardened raceways, combined with high-strength bearing steel (GCr15), enhance load capacity, reduce wear, and extend service life under heavy-duty conditions.

Long Life Lubrication System New

Long-life Lubrication System

High-performance grease such as lithium complex or calcium sulfonate, with extreme pressure (EP) additives, ensures stable lubrication under heavy loads. Optimized grease quantity and internal space design reduce metal-to-metal contact, prevent overheating, and extend relubrication intervals.

Self Aligning Bearing Structures

Self-aligning Bearing Structures

Self-aligning designs, such as spherical roller structures or optimized internal geometry, compensate for shaft misalignment and installation errors, reducing stress concentration and ensuring stable performance under dynamic operating conditions.

Optimized Clearance And Heat Treatment

Optimized Clearance and Heat Treatment

Precisely controlled internal clearance, combined with advanced heat treatment processes such as carburizing, induction hardening, or bainitic treatment, improves fatigue resistance, reduces heat buildup, and ensures dimensional stability under continuous operation.
