Engine crankshaft thrust bearings support axial loads and prevent crankshaft movement. They ensure proper alignment within the engine block. These bearings are critical for smooth engine operation and longevity.

Size: Typically ranges from 20 mm to 150 mm in diameter, depending on engine type.

Grade: Common grades include SAE 841 (for high-load applications) and SAE 15W-40 (for lubrication).

Viscosity: Recommended viscosity ranges from 5W-30 to 20W-50, depending on operating conditions.

Buoyancy: Not a critical property; primarily functions under load-bearing conditions.

Material: Usually made of steel-backed babbitt (lead-tin alloy), aluminum, or bronze for durability.

Load Capacity: Designed to handle axial loads up to 10,000 N in heavy-duty engines.

Thickness: Typically 2 mm to 5 mm, depending on engine design.

Operating Temperature: Withstands temperatures from -30°C to 150°C.

Lubrication: Requires engine oil with anti-wear additives for proper function.

Finish: Precision-ground to a surface roughness of 0.2–0.8 µm for smooth operation.

Yes, Engine Crankshaft Thrust Bearings and Engine Systems can comply with maritime standards such as ISO 15540, ISO 10438, and classification society standards from ABS, DNV, or Lloyd's Register, depending on the specific product and manufacturer.
