Finishing, trimming, rollover, grease filling, and visual inspection are all essential steps in manufacturing radial shaft seals.

Finishing is the process of removing any excess material from the seal, such as flash or burrs.

  • Improved appearance: The finishing process can enhance the seal's appearance, making it more aesthetically pleasing.
  • Improved durability: The finishing process can enhance the seal's durability, making it more resistant to wear and tear.
  • Reduced maintenance costs: The finishing process can reduce maintenance costs by extending the seal's life.

Trimming is the process of cutting the seal to its final dimensions.

  • Improved accuracy: The trimming process ensures accurate dimensions, which are essential for the seal to function correctly.

Rollover is the process to combine the 2 or 3 different sealing parts to create a unitized seal in a multipart (Cassette) seal type / combi seal. This helps in creating complex profiles with multiple lips and predominantly used in muddy / puddling applications where the external contamination is relatively high.

Grease filling is the process of filling the seal with grease.

  • Improved lubrication: The grease-filling process helps to lubricate the seal and prevent it from sticking.
  • Reduced wear and tear: The grease filling process can minimize wear and tear on the seal, extending its life.
  • Improved performance: The grease-filling process can enhance the seal's performance by reducing friction and heat generation.

Visual inspection is the process of visually inspecting the seal for any defects. Our expert inspectors look for defects such as cracks, tears, or voids.

  • Improved quality: The visual inspection process ensures that the seal is free of defects, which can improve its quality and performance.
