Rod Seal 620 Inch Size 'Hallite'

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.

OptiSeal JBR corrosion-resistant spring-loaded PTFE seal

OptiSeal JBR corrosion-resistant spring-loaded PTFE seal

A rod/piston seal compatible with the P-number grooves of JIS B2401, suitable for use in harsh environments. It features low friction and excellent heat and chemical resistance.

The Hallite OptiSeal JBR is a spring-loaded type seal for single pressure applications, compatible with the JIS B2401 P-type groove. It features a U-shaped seal jacket with a V-shaped corrosion-resistant metal spring integrated into its structure. When there is no load or at low pressure, the spring provides the necessary load to the seal lip, creating the appropriate contact surface pressure. As the operating pressure increases, the system pressure acts on the U-shaped area, influencing the sealing performance at high pressure. The standard material is a high-performance seal jacket made from PTFE (fluoropolymer). It demonstrates low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Excellent chemical resistance, adaptable to various applications - Low friction eliminates stick-slip phenomena - Compatible with JIS B2401 P-type grooves - Excellent wear resistance and long service life - Suitable for a wide temperature range - Superior dynamic and static sealing characteristics of tandem lips Hallite is a group company of Michelin.

V Ring Seal "SES"

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.
