In many applications, bearings and supports must work also in presence of filth, dust and chips. For this reason, they need continuous lubrication and maintenance interventions. Polymer bearings by igus are lubrication- and maintenance-free, even if the support is made of metal. Precisely for these systems with metal supports, igus has developed new iglidur J high-performance plastic bearings.
The new self-lubricating bearings with sheet metal housing allow notably decreasing maintenance costs. Moreover, this new material prevents the deposition of dirtiness and dust and this represents a considerable advantage in terms of wear and allows avoiding unforeseen machine downtimes. Igubal bearings are made through injection moulding and they are economically advantageous.
They can be mounted in few seconds to replace ball bearings in already existing standard metal housings or they can be bought with a low-cost sheet metal support. The joint is composed by the sheet metal housing and by igubal ball bearing and is directly available in stock. The plastic bearing has high resistance to wear and features a very low friction coefficient in dry operation.
Currently, igubal bearings are available in three sizes for low-cost sheet metal housings (Ø20, 25 and 30 mm) and for injection moulded housings (UC204-210).
