using a double needleOne of the biggest differences is in the motor. Heavy duty machines need to power through thick, layered, or dense fabrics without straining, so they have more powerful motors. Motors in heavy duty machines often range from 1 to 5 amps, while standard motors are usually around 1 amp or less. With the stronger motor, heavy duty machines can sew for longer periods without overheating or losing power. This makes them ideal for sewing operations like upholstery where seams need to go through multiple fabric layers.

The machine's robust build, typically made from high-quality cast iron, ensures longevity and resilience against the demands of regular use. Its intricate mechanism, with its precisely engineered needles and feed dogs, guarantees consistent stitches and seamless seams, making it ideal for creating everything from wallets, belts, and bags to saddles, boots, and automotive upholstery.
In addition to the type of needle point, the size of the needle is also important when sewing leather
industrial sewing machine needles for leather. The size of the needle refers to the diameter of the needle shaft, with larger numbers indicating thicker needles. For sewing leather, it is recommended to use needles with sizes ranging from 14 to 18, as these sizes are strong enough to penetrate through the material without causing damage.
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
For more severe oil-seal service at temperatures of 160°C (320°F) or higher for extended periods, more resistant fluoroelastomer compositions are required for long service life. High-fluorine VDF/PMVE/TFE elastomers, along with TFE/olefin FEPM elastomers, are much less susceptible to attack by oil additives. TFE/P fluoroelastomers have the requisite chemical resistance, but have low fluorine content, leading to relatively high swell and to soft vulcanizates with lower wear resistance than desired.
The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.
Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.

The Ultimate Guide to Oil Seals
Because synthetic motor oil can cost two to four times more than regular oil, talk to your technician about whether it’s the right oil for your car. If you live in a climate with super cold winters or very hot summers, or use your vehicle for towing or hauling, synthetic oil may be the best type of oil for your vehicle. Older engines could also benefit from synthetic oil, as it can help prevent harmful sludge build-up that some older engines seem to be prone to.

The skeleton oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension.
Similar to the housing surface stop technique, this method uses a stop at the machined housing face to set the seal depth. It is typically used in housings with flat outer surfaces. Verifying the placement through visual inspection or with a feeler gauge ensures placement accuracy.

Oil seals are installed beside the bearing while the flexible lip is pressed against the rotating shaft. The casing pressing into the housing holds the seal in place. The sealing lip is essentially lubricated to minimize the risk of overheating due to the generated friction.
