Self-Aligning Bearing Units
Chain & Drives supply ISB's Self Aligning Bearing Units.
ISB housings are constructed in multiple executions, with external parts in cast iron, bound with aluminium, in moulded steel sheets and in plastic.
The bearings used in ISB housings provide a sealing system on both sides. They are constructed with a seal which has synthetic rubber fixed to the external ring and is reinforced with the relative steel lip; while fixed on the inner ring there is a shield which turns together. This protective system prevents grease from exiting and pollutants from entering.
