Rotary shaft seals, also known as radial shaft seals, are increasingly finding their way into various industries. Through innovative mechanisms, they are becoming a standard component of food processors and electric vehicles. Rotary Shaft seals are also used to replace or upgrade the equipment of cement manufacturers.
The purpose of rotary seals is to avoid contamination or the spilling of the product. They protect the shaft from dust and dirt and keep water and lubricants inside the machine.
Rotary Shaft seals create a seal around a rotating shaft such as those used in screw conveyors, bulk handling equipment, or ribbon blenders.
Rotary seals such as those manufactured by Cinchseal are cost-effective and high-performing alternatives to mechanical elements such as O-rings, braided packing, lip seals, and mechanical face seals.
Rotary Shaft Seals Improve on Their Alternatives
Previously, rotary seal alternatives like lip seals consisted of small surfaces that grabbed the rotating shaft. This was more likely to allow contamination to leak. These other types often struggle to hold high pressure and don’t perform well in more challenging environments. Due to their stationary position, they cause friction and damage the rotating shaft rather than following along with its movement.
Design Innovation that makes the Rotary Shaft Seal stand out
Cinchseal’s rotary seals have innovated upon these flawed designs to improve the components’ lifespan and better protect the rotating shaft. The more resilient Cinsheal rotary seal is designed to withhold harsh environments that cause other seals to wear out quickly. The FDA-approved silicone elastomer moves with the shaft for lower friction and better-ensured coverage.
These seals, therefore, cause less maintenance and replacement costs.
Additionally, the seals come with a larger shaft/seal surface that interfaces between the two components, creating a super seal against contamination. They are available with polished stainless-steel plates and PTFE rotor cups to further improve leak prevention.
These add to the useful silicone elastomer by pressing against stationary faces with an optimal load. The rotary shaft seal rotor cups are boot-mounted, allowing the rotary assembly to float with the shaft. This avoids the standard ¼” misalignment typical for bulk handling equipment.
Cinchseal’s high-pressure rotary shaft seals push the rotors against the strator with nitrogen or air purging to close the sliding interface. The thereby created air barrier keeps the product out of the seal and performs excellently under high pressure.
Easy Installation of Rotary Shaft Seals
Rotary Shaft Seals designed by Cinchseal don’t require professional assistance for assembly or disassembly. \this is achieved through the split design that can quickly be taken apart for batch or weekly cleaning.
Rotary Shaft seals are also available for custom design, with dimensions specifically designed for a given application to reduce risks created by a mismatch of products.
Cost-Effectiveness of Rotary Shaft Seals
Rotary Shaft Seals can prevent many unnecessary costs and protect a manufacturer’s bottom line. Due to their high performance and price-value, they are highly cost-effective. Rotary Seals can stop material loss and reduce the need for maintenance and attendants. They function exceptionally well in challenging environments, limiting the need for repair and replacement.
Rotary Shaft Seals maintain a work environment free of contamination and therefore limits the associated costs of illness in employees.
The Bottom Line
Rotary seals are a simple concept, but their execution is a tough challenge to overcome. Cinchseal’s rotary shaft series deals with these technical difficulties and provides an innovative all-metal design that eliminates shaft damage and provides reliable sealing.
