SBT allowable shaft surface speed The sealing edge of the seal should provide constant sealing performance,maintaining contact with the shaft while accommodating shaft runout and housing bore eccentricity. When shaft rotation is extremely fast,the sealing edge eventually becomes unable to accommodate shaft runout and housing bore eccentricity,thus deteriorating sealing performance.The speed just before the sealing performance is deteriorated,is called the allowable shaft surface speed for seals. The allowable shaft surface speed for seal is mostly influenced by shaft runout.When total eccentricity is small,the allowable shaft surface speed is a constant value,depending on the rubber material and seal type.
