Timken® maintains inventory of most Carlisle® Sleeve sizes. Non-stock sizes will be indicated by an asterisk following the part number. Contact customer service for availability. Minimum order quantity and/or extended lead times may apply. Occasional production inconsistencies which may render a portion of the Sleeve unusable can be present as a normal part of the production process. Each Sleeve is inspected to ensure that it contains 90% or more usable product. A full width Sleeve with less than 10% unusable product is considered acceptable.
