For 40HP Yamaha Outboard Top Bearing Crank


The outboard engine is an essential component of a boat or watercraft, providing power and propulsion. The crankshaft is a key component of the outboard engine, responsible for converting the reciprocating motion of the pistons into rotational motion. The crankshaft bearing plays a crucial role in supporting the crankshaft and ensuring smooth and efficient operation. In this article, we will explore the different types of crankshaft bearings and recommend HIMARINE brand bearings for their high-quality and durability.
Types of Crankshaft Bearings
There are two main types of crankshaft bearings - journal bearings and ball bearings. Journal bearings are commonly used in outboard engines and consist of a shaft and two bushings that are inserted into the connecting rod. The connecting rod then connects to the crankshaft through the bearing. Journal bearings are designed to support high loads and provide good resistance to wear.
Ball bearings, on the other hand, consist of a series of balls that are held in place by two rings. Ball bearings are typically used in high-speed applications as they provide excellent support, reduce friction, and require less maintenance. However, they are not suitable for applications with high loads as they tend to wear out quickly.
