864

Penjual : Rumah Seal

The Hallite 864 is a double-lipped, metal-cased wiper is designed to press fit into open groove housings of popular Asian housing sizes for a wide range of applications and for use with venting U-rings, such as the Hallite 663 or Hallite 673 rod seal.

The polyurethane wiping element is bonded to a nitrided metal case eliminating the potential for rust. The polyurethane wiping element has a precision trimmed sealing lip to collect the fluid passing the rod seal and a specially wiping lip is textured to provide improved dry rod performance, particularly for long stroking cylinder applications.

The proportions of the polyurethane wiping lip follow the side movement of the rod to clear away heavily deposited dirt and make this wiper an excellent choice for dirty conditions.

847

Penjual : Rumah Seal

The Hallite 847 wiper has been specifically developed for cylinders used in demanding, heavy-duty off-highway applications in dirty environments, such as earth-moving excavators. This double-lipped wiper incorporates a special venting feature to permanently relieve pressure build-up between the rod seal and wiper. This prevents pressure from ejecting the wiper without the need for an expensive vent hole in the gland.

The flap on the wiping lip is another special feature that covers the gland housing and prevents the water/slurry trap that is common with conventional wipers. The design minimises oil transfer out of the ram on the rod and prevents dirt, contamination, and moisture from entering the cylinder through the gland.

The standard range is made from high-performance Hythane® 371 polyurethane. The wiper is also available in other polyurethane grades, if required, potentially extending the operating conditions.

846

Penjual : Rumah Seal

The Hallite 846 double-lipped, snap-in rod wiper is developed specifically for cylinders applications on mechanical handling equipment, particularly those with long stroke, and designed for use with venting U-rings, such as the Hallite 663 or Hallite 673 rod seal. The design minimises the oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing the rod seal.

The unique feature of the Hallite 846 is the Umbrella Wiper Technology, which is a protective debris guard flap on the wiping lip that entirely covers the gland housing and prevents the water/slurry trap that is common with conventional wipers. This feature offers added protection to the integrity of the hydraulic system by reducing corrosion and preventing the ingress of contamination into the wiper housing groove and hydraulic cylinder gland which will result in increased system life.

Another special feature of the Hallite 846 wiper design is the thin membranes which burst when excessive fluid pressure is trapped between the wiper and the rod seal. This prevents pressure from ejecting the wiper out of its housing. After release of this pressure, the membranes close to protect against contamination from the outside without the need for an expensive vent hole in the gland.

The Hallite 846 is moulded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance and has a textured wiping lip to provide improved dry rod performance, particularly for long stroking cylinder applications.

The Hallite 839N double-lipped, snap-in wiper is designed to fit popular Asian housing sizes, and to exclude dirt and moisture from entering the cylinder. The design minimises the oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing the rod seal.

The wiping lip on the Hallite 839N is textured to provide improved dry rod performance, particularly for long stroking cylinder applications. Opposite the wiper lip are two sealing lips that are precision trimmed at an angle to give optimal rod sealing performance. The Hallite 839N is designed to have an interference in the seal housing groove to improve the stability of the wiper in the gland and to reduce the possibility of ingress around the outside of the wiper.

Hallite recommends a vent is provided between the seal and the wiper to avoid a pressure trap.
