FAQ What is the significance of the ‘ISOCLASS’ marking?’ISOCLASS’ refers to the tolerance class of the bearing, indicating its dimensional and running accuracy according to ISO standards. This ensures interchangeability and precise fitting. Is this bearing pre-lubricated or does it require initial greasing?Tapered roller bearings like the 31308 are typically shipped with a preservative oil coating to prevent rust. They are not pre-lubricated for operation and must be cleaned and lubricated with the appropriate grease or oil upon installation. What is the correct procedure for mounting a tapered roller bearing?Mounting involves pressing the cone (inner ring assembly) onto the shaft and the cup (outer ring) into the housing. It is critical to apply pressure only to the face of the ring being mounted and to set the correct preload or end-play to ensure optimal performance and bearing life. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
