This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

The advantages of handheld bag closers are numerous. First and foremost, they significantly increase productivity. Traditional sealing methods, such as tying or manually stitching, can be time-consuming and labor-intensive. In contrast, a handheld bag closer allows operators to seal bags quickly, resulting in faster packaging times and increased output.

In addition to their durability, stitch machine embroidery designs also offer precision and accuracy. With the ability to program intricate patterns and designs into the embroidery machine, you can create flawless and detailed designs that would be difficult to achieve with hand embroidery. This precision is particularly useful when working on large-scale projects or intricate designs that require a high level of detail.

One of the most critical features to look for in a sewing machine for both fabric and leather is stitch control. The ability to adjust the stitch length and type is vital when switching between materials. For instance, when sewing leather, a longer stitch length (usually between 3-5mm) helps reduce the chances of puncturing the material too many times, which can lead to tearing. In contrast, for lightweight fabrics, a shorter stitch length provides greater control and a more refined finish.
