Frequent bearing failures in abrasive environments often start with dirt reaching the sealing zone. Heavy-duty COMBI oil seals help keep lubricant inside while limiting the entry of mud, dust and grit. They are a practical choice for operators dealing with recurring contamination, short maintenance intervals and costly equipment stoppages in construction, agricultural and industrial machinery.
Recurring seal changes are often a contamination problem, not just a seal problem. Heavy-duty COMBI oil seals help isolate bearings from abrasive mud, dust and grit while supporting lubricant retention. This reduces the conditions that lead to scoring, grease loss, overheating and repeated maintenance.
