Information about grease buttons

Kép
A grease gun, also known as a grease fitting, is a metal assembly used in mechanical systems to feed lubricants, usually greases, into the bearing under medium or high pressure using a grease gun. The grease knob consists of standard knob head grease fittings and metric knob head grease fittings. Grease nipples are designed for high flow of lubricant to provide a smooth working surface for easy connection and removal. Grease buttons can be permanently installed with a threaded or straight push-on ("hammer") arrangement, leaving a pipe connection to which the grease gun connects. The pressure provided by the grease gun forces the small bearing ball in the assembly to move back against the force of the retaining spring. The arrangement is therefore essentially a valve that opens under pressure and allows the lubricant to pass through a channel, thus entering the bearing cavities. When the pressure is released, the bearing returns to its closed position. The bearing ball exclude

Dimensions and applications of the O-ring

Kép
 An O-ring , also known as a seal or toric joint, is a torus-shaped mechanical seal, which is a loop of round cross-section designed to fit into a groove and compress during assembly between two or more parts, forming a seal on the surface. The O-ring can be used in static or dynamic applications where there is relative movement between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Static applications of O-rings may include liquid or gas sealing applications where: (1) the O-ring is compressed resulting in zero clearance, (2) the O-ring material is solid vulcanized so that it is impermeable to liquid or gas, and (3) O-ring material resists degradation by liquid or gas. The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide variety of materials. O-rings are one of the most commonly used types of seals in machinery design because they are inexpensive, easy to manufacture, re

What is a seal, what are its advantages?

 What is a seal ? Rubber gaskets are flexible components used to mechanically seal a microscopic gap between two mating surfaces or joints. Examples of such surfaces are the flange surfaces of pipes and fittings, the mating surfaces of the car cylinder head and engine block, the tank and its lid, door edges, frames and so on. Rubber gaskets seal surfaces by flowing into and filling surface irregularities in rigid parts. The sealing ability of rubbers is attributed to their elastomeric nature. Natural or synthetic rubbers belong to a family of materials called elastomers. Elastomers are a class of polymers that are highly flexible in nature and are created by cross-linking long polymer chains into amorphous structures. The intermolecular forces between polymer chains are relatively weak; this allows them to be reconfigured under stress. Thanks to this property, elastomer seals easily adapt to the profile of the surfaces, thus creating a tight seal. What are the advantages of seals? Com

What are plain bearings and what is their purpose?

Kép
 Plain bearings (e.g. bushings, ball joints) facilitate linear movement between two parts. Plain bearings consist of metal, plastic, or fiber-reinforced composite sleeves that reduce vibration and noise by absorbing friction between two moving parts in a sliding motion. Plain bearings have many advantages, including lower cost, less maintenance, and a large reduction in low-speed operation. The performance of sliding bearings is also characterized by a higher load capacity, especially due to their larger contact zone. Plain bearings with conformal liners compensate for misalignment problems and vibration damping. Plain bearings can be made of bronze, steel or stainless steel. Brass bearings and plastic sleeve bearings are also manufactured for certain applications. A common type of plain bearing that works well in applications that require constant lubrication are bronze bearings, which sometimes include grease plugs (PTFE or graphite) to solve lubrication problems.

Roller bearing types and areas of application

Kép
 Roller bearings – also known as roller bearings – are similar to ball bearings in that they are designed to carry loads while minimizing friction. However, roller bearings transfer the load using cylindrical rolling elements instead of balls to maintain the distance between the moving parts of the bearing. These versatile bearings can contain one or more rows of rolling elements. Those roller bearings that contain several rows of rolling elements can significantly improve the radial load capacity. In addition, the use of different roller shapes can further reduce friction and support both radial and axial loads. Roller bearing types and their application Thousands of different types of roller bearings are available to meet specific application requirements. There is a wide variety of roller bearings, including the following popular types: Spherical roller bearings These can carry heavy loads even if they struggle with displacement and shaft deflection. They can be designed with cylin
