What is an axial misalignment?

An axial misalignment is a state where the shafts are parallel to each other. When fully extended, their ends do not meet, thus creating a floating effect.

What is the function of U-joint spiders?

The U-joint spiders have the shape of a cross (with four arms) that connect the yokes, allowing for angular misalignment and shaft separation. The spider distributes the load evenly across the joint, reducing the risk of damage.

What is the meaning of precision-honed bore?

Precision-honed bore refers to the process of honing intended to perfect bore geometry and size by removing a minimal metal layer. It also generates a smooth pattern finish for optimum lubricant retention and minimises friction and wear.
