CAT 584-9023 BEARING-SLV-GD

CAT 584-9023 YM is a Caterpillar genuine heavy-duty machinery sleeve bearing used for shaft support and positioning in gearboxes, final drives, and other components. The following is the original data and does not include replacement parts information.

Core Technical Parameters (Raw Data)

Item Details
Basic Attributes
Model 584-9023 YM, Type: Straight-tube sleeve bearing, Material: Tin bronze (CuSn8P), Single weight: 0.92 kg, Applicable operating conditions: Low speed, heavy load, radial positioning of shaft, Operating temperature: -30℃ to +120℃, Rated dynamic load ≥180 kN, Rated static load ≥320 kN, Applicable shaft diameter: φ85 mm, Used for gearbox input shaft and final drive support shaft

Key Dimensions (Metric/Imperial)
Inner diameter: 85.0 mm (3.346 in, tolerance 0/-0.02 mm), Outer diameter: 110.0 mm (4.331 in, tolerance 0/-0.03 mm), Overall length: 95.0 mm (3.740 in, tolerance ±0.15 mm), Wall thickness: 12.5 mm, Inner bore surface roughness: Ra≤0.4 μm, Interference with shaft 0.015-0.025 mm, clearance to mounting hole 0.01-0.02 mm

Performance Parameters: Material hardness HB 90-110, coefficient of friction ≤0.12 (oil lubrication), limiting speed 1200 rpm (oil lubrication), permissible radial load ≤150 kN, compatible with Cat DEO-ULS 15W-40 engine oil, oil-resistant, corrosion-resistant, with no significant angular misalignment.

Structure and Compatibility Characteristics:

Tin Bronze Material Advantages: CuSn8P bronze possesses excellent friction reduction and wear resistance, allowing for short-term operation without additional lubrication under low-speed, heavy-load conditions. Suitable for impact load conditions in engineering machinery, and less prone to seizing, wear, and other failures in Cat® Parts.

Straight Cylindrical Structure Positioning: Flangeless design, fixed in the mounting hole via interference fit, ensuring radial positioning accuracy of the shaft, reducing operating vibration, and suitable for parts requiring high coaxiality, such as gearbox input shafts and final drive support shafts.

Operating Condition Adaptability: Suitable for low-speed, heavy-load, and frequent start-stop conditions in heavy machinery. It has a wide operating temperature range and can operate stably in dusty and humid environments. Long-term deformation is ≤0.03 mm.

Installation and Maintenance Points (Original Data)

Installation: Clean the journal and mounting hole (free of oil and burrs). Use cold-press installation (pressure ≤150 kN). After installation, the bearing end face should be flush with the mounting surface. The shaft should rotate freely without jamming. The interference fit between the bearing and the journal should be 0.015-0.025 mm, and the clearance between the bearing and the mounting hole should be 0.01-0.02 mm.

Maintenance: Check lubrication and wear every 1000 hours. Replace when the radial clearance exceeds 0.2 mm. For long-term storage, apply anti-rust oil and seal to prevent bronze oxidation.
