33 – wiper suitable for a grooved housing

Product catalog summary

Design Specifications:
The Hallite 33 wiper is designed with a lip to remove lightly adhered dirt such as mud, dust, or moisture from the rod. It is made from hard nitrile rubber and is suitable for installation in a grooved housing. For rod diameters of 20mm and below, a two-piece housing is required. The wiper's outside diameter is an interference fit with the housing to prevent dirt passage and reduce pumping action. Some sizes conform to ISO 6195 Housing Type A, and the inch profile differs from the metric profile.

Operating Conditions:
Maximum speed is 4.0 m/sec (12.0 ft/sec), and the temperature range is -30°C to +100°C (-22°F to +212°F). Surface roughness for the dynamic sealing face is 0.1 to 0.4 µmRa, with a maximum of 4 µmRt. Static sealing faces have a maximum roughness of 2.5 µmRa and 16 µmRt.

Radii and Tolerances:
For rod diameters up to 200mm, the maximum fillet radius r1 is 0.4mm, increasing to 0.8mm for diameters over 200mm. Tolerances for Ød1, ØD1, ØD2, and L1 are specified in both metric and inch units.

Features:
The wiper is a general-purpose component available in a wide range of sizes, providing an effective seal on both the housing and the rod.

Technical Details:
Detailed dimensions and tolerances are provided for both metric and inch sizes, including part numbers and specific measurements for ØD1, ØD2, L1, and L2.

33 – wiper suitable for a grooved housing-1

The Hallite 33 wiper has a lip designed to remove lightly adhered dirt from the rod i.e. mud, dust or moisture. The wiper is manufactured from a hard nitrile rubber suitable for installing in a grooved housing. Rod diameters (Ød1) of 20mm and below require a two piece housing . To prevent dirt passing the outside of the wiper and to reduce the pumping action, the outside diameter is an interference fit with the housing. Certain sizes of the standard Hallite 33 metric range are suitable for ISO 6195 Housing Type A. It should also be noted that the Hallite 33 inch profile differs from the metric profile. NB: Part numbers suffixed by “‡” indicate housing sizes to meet ISO6195A. Many of the metric sizes are also available as polyester wipers – see Hallite 38.
