When selecting rock drill tools for tunnel drilling, it is important to consider several factors, including the type of rock formations to be drilled, the size and depth of the tunnel, and the available drilling equipment
In this blog, we attempt to highlight what are Oil Seals and the various Rotary Shaft Seals including Mechanical Face Seals, Water Pump Seals, Gland Packings, and V-Seals that are readily available.

Polyacrylate (ACM) Oil Seals

There are a wide variety of industrial applications and therefore there are a wide variety of oil seals to meet the specific application needs. By choosing the right oil seal you will have a better fit, improved stability, and enhanced reliability. Rubber tends to be one of the most commonly used oil seal materials. an oil seal manufacturer, explains how oil seals for and the importance of proper installation, “To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. The shaft counterface surface and housing bore should meet the demands specified in the sections Shaft requirements and Housing bore requirements. To facilitate seal installation and to achieve initial lubrication, prior to installation, recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.

The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.

Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.

High mileage oil is specifically designed for cars with more than 75,000 miles. This type of oil can help reduce oil consumption, minimize leaks and oil seepage, and can also help reduce smoke and emissions in older engines.
