perma CLASSIC

perma CLASSIC can be used for all applications with ambient temperatures of 0 to +40 °C. The reliable operating principle is based on an electrochemical reaction. The lubrication period is determined by color coded activator screws. Depending on your application's requirement, you may choose to discharge 120 cm³ in a period of 1, 3, 6 or 12 months. The activator screw generates pressure (max. 4 bar) which moves the piston forward and continuously injects small lubricant amounts into the lubrication point. perma CLASSIC is fully dust and water proof and can withstand impacts and accidental knocks.

Applications

perma CLASSIC is a single-point lubrication system for roller- and sliding bearings, sliding guides, open gears, gear racks, spindles, shaft seals, chains, etc. operated at ambient temperatures that reach from 0 up to +40 °C. Typical applications can be found in mining, steel, automotive and mechanical engineering.

There are several ways to seal a hydraulic cylinder, and using different types of seals can help prevent leaks and ensure proper operation of the cylinder. Here are a few ideas:

Use a piston seal to create a barrier between the moving piston and the cylinder wall. This can help prevent fluid leakage and reduce friction. Synonyms for piston seal include:

O-ring
Gasket
Packing

Use a rod seal to seal the gap between the rod and the cylinder head. This can help prevent fluid from escaping and can also help reduce friction. Synonyms for rod seal include:

Lip seal
U-cup seal
Scraper seal

Use a wiper to remove contaminants and debris from the rod as it moves in and out of the cylinder. This can help prevent damage to the seals and improve the overall performance of the cylinder. Synonyms for wiper include:

Scraper
Cleaner
Brush

Use a guide band to help position the rod and prevent it from tilting or misaligning as it moves within the cylinder. Synonyms for guide band include:

Guide ring
Guide bushing
Guide sleeve

It's important to use the appropriate seals and other components for your specific hydraulic cylinder to ensure proper sealing and operation.

There are several ways to seal a hydraulic cylinder:

1. Piston seal: This is a sealing element that prevents fluid from leaking past the piston as it moves within the cylinder. Some synonyms for this component include: O-ring, packing, seal ring.

2. Rod seal: This is a sealing element that prevents fluid from leaking past the rod as it extends and retracts within the cylinder. Some synonyms for this component include: lip seal, scraper seal, dynamic seal.

3. Wiper: This is a component that removes contaminants and debris from the rod as it extends and retracts within the cylinder. Some synonyms for this component include: dust seal, dirt scraper, rod protector.

4. Guide band: This is a component that helps guide the rod as it extends and retracts within the cylinder. Some synonyms for this component include: guide ring, guide bushing, rod guide.

It's important to properly seal a hydraulic cylinder to ensure the system operates efficiently and effectively. Using high-quality sealing elements and regularly maintaining and replacing them as needed can help prolong the life of the cylinder and prevent costly repairs.

A slydring is a type of hydraulic seal specifically designed for use in high-pressure, high-temperature environments. It is made of a special material called PTFE (polytetrafluoroethylene) that is resistant to wear and abrasion, and it is used to seal the gap between a piston rod and a cylinder bore in a hydraulic cylinder.

A glydring is a type of hydraulic seal that is similar to a slydring in that it is made of PTFE and is used in high-pressure, high-temperature environments. However, a glydring is designed to seal the gap between two moving parts in a hydraulic system, such as between a pump and a motor or between two rotating shafts.

A slydring is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system. It is typically made of a flexible material such as rubber or polyurethane and is designed to provide a low-friction seal that prevents leakage of fluid or contaminants from the system.

A glydring is a type of seal that is similar to a slydring but is made of a material that is resistant to high temperatures and is specifically designed for use in high-temperature applications. It is often used to seal gaps between moving and stationary components in high-temperature hydraulic systems or in other high-temperature environments.

A single acting piston seal is a type of seal that is used in a hydraulic cylinder that only applies pressure in one direction. This type of seal is typically used in applications where the cylinder only needs to extend or retract, such as in a dump truck hoist or a car jack.

A double acting piston seal, on the other hand, is a type of seal that is used in a hydraulic cylinder that applies pressure in both directions. This type of seal is typically used in applications where the cylinder needs to extend and retract, such as in a hydraulic press or a hydraulic lift.

An example of a single acting piston seal might be a rubber o-ring that is used to seal the gap between the cylinder and the piston in a single acting hydraulic cylinder. An example of a double acting piston seal might be a pair of u-shaped seals that are used to seal the gap between the cylinder and the piston in a double acting hydraulic cylinder.

A single acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to only one side of the piston. This type of seal is typically used in applications where the piston only needs to move in one direction. An example of a single acting piston seal is a seal used in a hydraulic jack or a hydraulic press.

A double acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to both sides of the piston. This type of seal is typically used in applications where the piston needs to move in both directions. An example of a double acting piston seal is a seal used in a hydraulic cylinder on a bulldozer or a hydraulic cylinder on a forklift.
