Sealing and securing elements

Seals and securing elements prevent the leakage of lubricant, the penetration of dirt and spontaneous loosening of components. The correct selection has a direct effect on the service life of bearings, shafts and entire mechanical units.

Soft sealing parts and precise metal locking elements meet in this group. Each type requires different data: for seals, size and material, for fuses, groove, diameter and method of assembly.

The most common mistake is to confuse a similar diameter or use an unsuitable material for the oil, temperature or pressure. For securing elements, the correct standard and thickness are also critical.

• for gufers, measure shaft, body and width
• for O-rings, determine the inner diameter and cross-section
• for Seger fuses, verify type for shaft or hole
• for nuts and washers, check thread, bearing surface and load
