Accommodating misalignment

A recent survey by a global bearing manufacturer concluded that around 25% of all rolling element bearings fail prematurely due to ineffective and inefficient seals. One design consideration often overlooked by end users and OEMs which can negate a seal's effectiveness and result in early failure is shaft misalignment.

For peace of mind all of Revolvo's SRB split roller bearings are designed to accommodate shaft misalignment without reducing the effectiveness of the seal. The SRB bearing's design locates both the bearing and the seal within a separate swivelling housing, which is then located within a support pedestal. The external surface of the housing and the internal surface of the support pedestal are spherical, creating a swivelling socket joint which accepts up to ±3° of static misalignment and ensures that seals always remain concentric to the shaft.
