Consider a fictional example: Sarah, a budding fashion designer, started with a standard machine. Over five years, she spent an average of $100 annually on maintenance, and by the sixth year, she had to replace the machine, costing her another $400—her total expenditure over six years: $1000.

Heavy duty pattern sewing machines are built to withstand the rigors of regular use. Constructed with a robust metal frame, these machines provide stability and reduce vibrations, resulting in more precise stitching. Whether you're working with thick fabrics like denim, leather, or canvas, the heavy-duty construction ensures that the machine can handle tough materials without skipping stitches or breaking needles. This durability is particularly appealing for those who often find themselves tackling ambitious sewing projects that demand high performance.

The Dressmaker Zig Zag Sewing Machine stands out for its user-friendly features that cater to both beginners and seasoned sewists. One of its most notable features is the adjustable stitch width and length, enabling users to customize their stitches for specific projects. This feature is particularly beneficial for tasks such as sewing curves or finishing edges, where a zigzag stitch can prevent fraying and provide a professional finish.

Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.

Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

Before you start installing oil seals, you need to choose the right size and type of oil seal for your application. Oil seals come in a variety of sizes and materials, so it's important to choose the right one for your needs. Consider factors such as temperature, pressure, and fluid compatibility when choosing an oil seal.
