Roll2Seal® – Without Lubrication
The recommended lead-in chamfers of 15 to 20 degrees do not yet guarantee trouble-free installation by causing the seal to slip into the bore. Elastomers may exhibit considerable friction on dry, non-lubricated surfaces. While this is a desirable characteristic for instance on vehicle tires, it proves to be a major obstacle when installing seals. Consequently, a sufficient reduction of the friction coefficient between the seal and the chamfer by means of lubrication or an anti-friction coating is a prerequisite for seal installation.
The Roll2Seal® principle may be helpful here as well whenever the required friction factor cannot be achieved due to lack of lubrication, for instance on account of chemical incompatibility with lubricants, dispensing with paint-wetting impairment substances or simply for cost reasons, because high friction forces have no adverse effect on the assembly process of Roll2Seals®.
