Using sealed bearings
Using sealed bearings in housings with standard seals is a good solution for highly contaminated environments. The sealed bearing together with the housing seal and grease provide three layers ofprotection (→ SKF Three-Barrier Solution). SBD plummer block housings and THD take-up housings can, in most cases, be used together with SKF sealed self-aligning bearings. When using taconite heavy-duty seals, a sealed bearing does not enhance the sealing effect during operation, but still protects the bearing against contaminants during mounting.
