1. O-Rings Are Simple, but Not Forgiving An O-ring is a circular-section elastomeric seal installed in a groove and compressed to seal oil, water, air, gases and other media. It can be used in static or dynamic service. If material, size or groove conditions do not match the application, typical failures include cuts, swelling, compression…
1. A Hydraulic Cylinder Needs a Seal System A hydraulic sealing system is the combination of seals used on moving parts of hydraulic equipment. A typical cylinder uses a piston seal, rod seal, wiper, guide or wear ring, and in some designs buffer or support components. Each item has a different job, so selection must…
1. What a Radial Shaft Seal Does A radial shaft seal is a contact-type dynamic seal used between a rotating shaft and a stationary housing. It retains lubricant, limits leakage, and helps prevent dust, water and other contaminants from entering the machine. Engines, gearboxes and geared motors are common applications. Note: Key point: A shaft…
For construction equipment, mining machinery and harsh-duty drivetrain systems. Metal face seals are selected where mud, abrasive particles, corrosive media and high loads make conventional radial lip sealing unreliable. This guide explains the selection and installation logic for Cat Duo-Cone and Heavy Duty Dual Face Seals. 1. Why metal face seals suit harsh-duty equipment A…
Learn how to use a decimal-inch vernier caliper and calculate a 0.001-inch reading for outside, inside, depth and step measurements.
Learn how to use a metric vernier caliper for outside, inside, depth and step measurements, and how to calculate an accurate metric reading.
O-rings, also known as O-ring seals, are rubber rings with a circular cross-section. They are one of the most widely used sealing solutions in hydraulic, pneumatic, and mechanical systems. Thanks to their excellent sealing performance, simple design, and versatility, O-rings can be used for both static and dynamic applications. When the right material is selected, they can handle pressures from vacuum (1.333 × 10⁻⁵ Pa) up to 400 MPa and temperatures ranging from -60°C to 200°C.
