Designed to carry high loads generated by a cantilevered enclosure, the Power-Core(TM)roller with integrated roller bearing is quiet enough to be designed into incubators for neonatal wards. The precision-machined roller generates low rolling resistance. The tire material doesn't absorb moisture, is dimensionally stable, absorbs shock and vibration, and resists wear. The part suits indoor and outdoor applications and has a temperature range of -40 to 120F.
