1. Leak Prevention One of the primary functions of a hub oil seal is to prevent oil leaks. If the oil seal fails, the lubricant can escape, leading to insufficient lubrication of the bearings and other critical components. This can result in increased wear and tear, decreased performance, and eventually, catastrophic failure.
The sealing lip is designed to conform to the shaft, creating a tight barrier that minimizes fluid escape
. Depending on the application, rotary shaft seals can be designed for various shaft diameters and operating conditions, including temperature extremes and high pressures.

As the artisan operates the manual machine, the rhythmic motion of turning the hand crank offers a unique connection to the craft. This hands-on approach allows for greater control and precision, facilitating intricate designs and tighter stitching. The manual machine's ability to sew with various thicknesses of leather enables craftsmen to create a wide range of products, from sturdy belts and wallets to intricate bags and holsters.
