Rod Seal 620 Inch Size 'Hallite'

A twin lip rod seal with precisely trimmed sealing lips, providing dry sealing solutions for light and medium load applications!

Hallite 620 is made of polyurethane and operates with a high-quality O-ring built in. The sealing lip is trimmed at an angle to optimize the sealing performance of the rod. Hallite 620 is designed to interfere with the groove of the seal housing and the secondary lip. The secondary sealing lip, positioned behind the primary sealing lip, enhances the stability of the seal within the gland. At zero or low pressure, the O-ring increases sealing force and prevents leakage. Under most conditions, as pressure rises, the sealing force increases, ensuring the full operation of the lip by the O-ring. Combining these features improves both lifespan and sealing capability. 【Features】 ■ Excellent low-temperature properties ■ Improved shock load resistance ■ Low friction ■ Enhanced sealing stability ■ Protection of the primary sealing lip ■ Easy installation Hallite is a group company of Michelin.

V Ring Seal "SES"

The V-ring seal is stretched and installed on the shaft, sealing axially against a stationary counterpart surface that is perpendicular to the rotating shaft.

V-ring seals are very easy to install as they are made of rubber materials such as NBR and FKM. The counterface can be the side wall of a bearing, a washer, stamping, a bearing housing, or the metal ring of an oil seal. The seal lip is flexible and makes contact with the counterface with relatively light contact pressure, accommodating relatively large axial and radial misalignments, and sealing out dirt, dust, debris, and splashed water. They are ideal for protecting main seals like oil seals and serve as secondary seals.

Air Pressure Cushion Seal 661 'Hallite'

Polyurethane cushion seal with a check valve function designed for pneumatic applications.

Near the stroke end of the cylinder, the protrusion of the cushion seal contacts the taper or R of the piston rod and is pressed against the cushion seal groove. This traps air between the seal and the piston, absorbing shocks by slowing down the movement of the piston. When pressure is applied to the extension side of the system, the compressed pressure is released to the piston side through the special vent groove on the side of the cushion seal. Hallite 661 is made from Hallite's high-performance polyurethane, Hythane 181, and is easy to install, has excellent low-temperature performance, and offers a long service life. 【Features】 ■ Check valve function ■ Excellent durability ■ Wide temperature range ■ Easy to install Hallite is a group company of Michelin.

[Success Case] Improvement System for Air Swivel Joints

Solving the issues of durability of rubber seals and unstable torque! Here we present a case where the lifespan was extended with a specially designed seal for low pressure.

We would like to introduce a case study on the system improvement of air swivel joints. The existing X-ring (NBR) had issues such as significant permanent compression deformation at high temperatures, and a decrease in wear resistance, leading to a negative spiral state where it lost its sealing function relatively early. Therefore, we specially designed a low-pressure version compatible with pneumatic systems based on Hallite's swivel seal SSR. This resulted in stable torque and extended lifespan. 【Case Overview】 ■ Equipment: Measurement device ■ Application: Air rotary joint ■ Challenge: Short durability ■ Result: Stable torque and extended lifespan *For more details, please download the PDF or feel free to contact us.

【Pump Trivia】About Seals

We will introduce representative seals (shaft sealing devices) used in the rotating parts of pumps!

There are two typical seals used in the rotating parts of pumps: "mechanical seals" and "packing seals." Packing seals seal the fluid inside the pump through contact pressure. In the shaft sealing area of the pump, a slight leakage that travels along the shaft surface is necessary for cooling and lubrication of the packing. On the other hand, mechanical seals are devices that minimize fluid leakage, offering the advantages of low leakage amounts and infrequent replacement. 【Features of Mechanical Seals】 ■ Shaft movement: Rotation ■ Leakage amount: Extremely low ■ Lifespan: Long ■ Power loss: Small friction area and friction coefficient result in low power loss ■ Replacement work: Requires disassembly of the pump *For more details, please refer to the PDF materials or feel free to contact us.
