Definitions:

U-joint Operating Angles

U-joint Operating Angles refer to the angles at which universal joints (U-joints) operate, connecting rotating shafts in a drive system, crucial for efficient power transmission and reducing wear.

Out-of-Balance

Refers to an uneven distribution of weight causing parts of a rotating object (like a tire or drive shaft) to move unevenly, often resulting in vibration or uneven wear.

Trunnion Seals

Seals used in the trunnion area of a machine or vehicle to prevent leakage of fluids around the trunnion bearings.

Universal Joints

Mechanical connections between rotating shafts, typically in vehicle drivetrains, allowing for transmission of torque and rotary motion even at angles.
