ZF S542 Input Shaft Seal

Ok got trans out and old seal out. However(BIG HOWEVER) new seal from Ford or Autozone is 50mm x 35 mm. The hole size around the shaft is 42mm, so I'm assuming a special(non-stock seal will have to be found. You can't push a 50mm seal in though a 42mm hole. I've thought about die grinding lip out of the way so stock seal will …

Radial shaft seals | SKF

The lip has a sealing edge that is formed by moulding, cutting or grinding. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring. The edge of the sealing lip and the shaft counterface surface form the most important functional area of a radial shaft seal.

Optimize shaft surface finish for maximum seal performance

Figure 3. In addition to shaft lead, these characteristics influenced sealability. They incorporated a variety of methods used to finish the shaft at the seal contact area, including plunge grinding, paper polishing, "as drawn," roller / diamond burnishing and ceramic turned with high-speed tool.

Rotary Seal lip Design and Geometry

grinding. Shaft finish is important because as the shaft rotates it will wear away a little rubber from the seal tip. If the shaft is to smooth, then not enough lip abrasion will occur. If the shaft is too rough, then excessive wear will occur. As optimal wear occurs, mircoaspreties will form on the seal lip.

Technical Specification | SKF

Radial shaft seals designed with a metal case and a secondary reinforcement in the side face ... Depending on the direction of rotation, directionality on the seal counterface may cause a seal to leak. Plunge grinding is the preferred machining method to minimize directionality (0±0,05°) on the seal counterface. When plunge grinding, whole ...

Beyond Ra: Why Surface Finish Matters in Seal …

There is a direct relationship between quality of a seal's mating surface finish and a seal's performance, the better the finish, the longer seal will last. ... including plunge and centerless grinding, …

Surface Preparation for Radial Lip Seals | ESP International

Plunge Grinding: The Grinding wheel is normal to the shaft axis at contact and does not traverse back and forth. The result is short to medium grinding marks that have little to no lead. This process can be relatively expensive but only needs to be performed in the seal contact region.Grade: A: Paper Polishing

Directions for crankshaft grinding and polishing

The surface lay generated by grinding would cause abrasion to the bearing surfaces if left unpolished. By polishing in the direction shown in either the figure 3 or 4, the surface lay is reversed by the polishing operation removing fuzz created by grinding and leaving a surface lay which will not abrade the bearing surface.

General | Shaft Prep for Oil Seal

Its not a nasty outdoor environment (machine tool input shaft) and not submerged, just "splash" and the oil seal I ordered has an additional wiper lip in addition to the actual sealing surface, so I'm not worried so much about grit grinding a …

Counter-surface finish properties | SKF

The counter-surfaces of static seals exposed to pressure, including the static side of dynamic rod and piston seals, should have a roughness Ra ≤ 0,8 μm (30 μin.). Seat diameters of guide rings and wiper seals should have a roughness of . Ra ≤ 1,6 μm (63 μin.). Axial faces of all grooves should have a roughness of . Ra ≤ 3,2 μm (125 ...

Technical Data (Factors Affect Sealing)｜WLK Oil Seal

Since the sealing lip contact directly to the shaft, the shaft finish is important for proper seal performance. The shaft finish should be 10-25 micro-inches AA with no machine lead. This shaft finish can be obtained by plunge grinding. Machine lead (helical scores) causes abrasion to sealing lip and possibly act as a pump that give rise to ...
