CAT 360-2319 BEARING-SLV-GD

CAT 360-2319 is a Caterpillar genuine YM straight heavy-duty sleeve bearing (suitable for low-speed, heavy-load, oscillating conditions such as excavator boom/stick pins and loader bucket hinge points, used to withstand radial loads and ensure smooth operation of the hinged parts). The following is pure original data and does not include replacement parts information.

Core Technical Parameters (Raw Data)

Compatible Models and Parts: Compatible with the lower hinge point of the boom of the Cat 320D2 excavator and the bucket pin of the 950M loader. One piece per part. Suitable for low-speed swing and heavy radial load conditions, ensuring wear resistance and stability of the hinged joint.

Performance Parameters: Impact load capacity ≥250 kN, wear resistance ≥6500 hours (normal lubrication), pin fit accuracy H7/h6, grease filling amount 12 cm³, compatible pin diameter 50 mm, surface hardening layer depth 0.8-1.2 mm

Structural and Performance Advantages: Straight sleeve structure: flangeless design, compatible with standard pin installation, compact structure, convenient installation, suitable for space constraints in the hinged parts of construction machinery.

Surface hardening treatment: Improves surface hardness and wear resistance, suitable for low-speed, heavy-load, and impact conditions, extends the service life of bearings and pins, and reduces maintenance frequency.

Precise clearance control: Radial clearance adapts to the thermal expansion and contraction of the pin, preventing jamming, ensuring smooth movement of the hinge, and reducing frictional loss.

Installation and maintenance points (raw data)

Installation: Clean the bearing and pin/mounting seat. Install using the cold pressing method (pressure ≤80 kN), ensuring the end faces are flush. After installation, radial runout ≤0.020 mm, pin surface roughness Ra ≤0.1 μm. Welding or heat fitting is prohibited to prevent bearing deformation.

Maintenance: Replenish grease every 400 hours, with the grease volume being 1/3-1/2 of the bearing volume. Check wear every 1800 hours. Normal use is possible when the inner diameter wear is ≤0.10 mm; replace the bearing and pin if the wear exceeds this limit.

Troubleshooting: For swinging or jamming, check lubrication and cleanliness; for abnormal noise, check radial clearance and fit accuracy; for abnormal wear, repair seals and lubrication, and replace relevant parts in a timely manner.
