The CAT 584-5764 YM sleeve bearing is a genuine Caterpillar bimetallic radial plain bearing (bearing type), suitable for low-speed, heavy-duty rotating parts in engines/transmissions. It is used to withstand radial loads and reduce journal friction. The following is raw data and does not include replacement parts information (Cat® Parts).
Core Technical Parameters (Raw Data)
Item Details
Basic Attributes
Model 584-5764 YM, Type: Bimetallic Radial Sleeve Bearing (Steel Back + Babbitt Metal), Material: Low Carbon Steel (Q235/SPCC) for the steel back, Tin-based Babbitt Metal liner (SnSb11Cu6, containing 90% tin, 11% antimony, and 6% copper), Single Weight 1.2 kg, Operating Temperature -30℃ to +150℃, Rated Radial Dynamic Load 220 kN, Rated Radial Static Load 450 kN, Limiting Speed 800 rpm, Coefficient of Friction ≤0.08 (Oil Film Condition), Corrosion Resistance Grade IP65, Service Life ≥10000 hours, Applicable Pressure ≤15 MPa, Oil Film Thickness ≥0.02 mm, Static Compression Deformation ≤10% (70℃×22 hours)
Key Dimensions
Inner Diameter 65 mm (2.559 in, H7 tolerance + 0.030/0 mm), outer diameter 85 mm (3.346 in, g6 tolerance 0/-0.022 mm), total length 120 mm (4.724 in), wall thickness 10 mm (steel back 3 mm + alloy layer 7 mm), chamfered ends 1×45°, steel back surface roughness Ra 1.6 μm, alloy layer surface roughness Ra 0.8 μm, cylindricity ≤0.015 mm, coaxiality ≤0.02 mm, compatible journal diameter 65 mm (h6 tolerance), mounting hole diameter 85 mm (H8 tolerance)
Compatible Models and Parts: Compatible with Cat C15/C18 engines, D9R/D10T bulldozers, and 793F mining truck crankshaft connecting rod journals, camshaft supports, and drive gear shaft ends. Installed in bearing housing holes to support rotating journals. 1 unit per part. This component is suitable for low-speed, heavy-load, and impact-load conditions, and is compatible with Cat DEO oil lubrication systems.
Performance Parameters: Babbitt alloy hardness HB 25-35, steel backing tensile strength ≥370 MPa, alloy layer bonding strength ≥150 MPa, wear resistance (wear rate ≤0.005 mm/1000 hours), thermal conductivity ≥50 W/(m・K), linear expansion coefficient 18×10⁻⁶/℃, oil resistance (compatible with Cat DEO engine oil and hydraulic oil, volume change ≤5%, 70℃×168 hours), fatigue strength ≥±180 MPa (10⁷ cycles).
Structural and Performance Advantages: Bimetallic composite structure: The steel backing provides rigid support, while the Babbitt alloy liner has excellent embedding, conformability, and anti-galling properties, compensating for installation errors between the journal and bearing housing, absorbing impact vibration, and protecting the journal from wear.
Precision Dimensioning and Tolerance Control: Inner diameter H7, outer diameter g6 tolerance, cylindricity ≤0.015 mm, ensuring proper fit with journals/bearing housings, forming a stable oil film, reducing friction loss and heat generation.
Long-lasting Wear-resistant Design: Babbitt alloy formula suitable for harsh working conditions in engineering machinery, oil-resistant and aging-resistant, with a service life of over 10,000 hours, reducing equipment maintenance frequency and costs.
Installation and Maintenance Points (Original Data)
Installation: Clean the bearing housing bore and journal (free from oil, burrs, and scratches), cold press installation (pressure ≤100 kN, avoid local deformation), after installation, cylindricity ≤0.015 mm, radial runout ≤0.03 mm, welding or heat installation is prohibited (temperature >100℃ will damage the alloy layer bonding strength), after installation check the oil hole alignment (deviation ≤0.5 mm) to ensure smooth lubrication.
Maintenance: Check bearing temperature every 800 hours (≤80℃), oil film pressure every 1500 hours (≥0.2 MPa), and inner diameter wear every 2000 hours (replace if wear >0.15 mm). Avoid overload (≤120% of rated load) to prevent alloy layer peeling or cracking.
Troubleshooting: Abnormal bearing noise is often due to insufficient lubrication or oil film rupture; check the lubrication system and add oil. Journal wear is often due to excessive bearing clearance; replace the bearing and repair the journal. Alloy layer peeling is often due to improper installation or overload; investigate the installation process and operating conditions.
