To complement our line of spherical roller bearings, we offer bearing sleeves and locking devices in a wide range of metric sizes.  These accessories are manufactured to the same quality standards as our bearings, ensuring a secure fit to straight and stepped shafts.  Available in sizes up to 900 mm, bearing sleeves are offered in two distinct designs: assembled sleeves and withdrawal sleeves.

 

 

 Design Attributes

• Adapter sleeves are used with a nut and locking device to simplify mounting a tapered bore bearing on a straight shaft using a pull-type fit.
• Withdrawal sleeves feature a push-type mounting arrangement and a locking device to secure a bearing to a shaft.

 

Applications

• Accessories ease the mounting and installation of spherical roller bearings onto shafts in a variety of applications.

 

Adapter Sleeves Timken adapter sleeves are used in conjunction with a nut and locking device to mount a tapered bore bearing onto a straight shaft using a pull-type fit.  Smaller size assemblies (17mm - 200mm shaft) commonly use simple nuts, whereas larger assemblies (sized >200mm) may use HMV hydraulic nuts to assist in mounting.  The chart below outlines our part number nomenclature, which is consistent with the world standards for adapter sleeves.

Withdrawal Sleeves Withdrawal sleeves feature a push-type mounting arrangement and a locking device (i.e., locknut or lock plate) to secure a bearing to a shaft.  This design is not as widely used as the adapter sleeve assembly and it does require the use of a spcially designed dismounting nut.  Timken's part number nomenclature for withdrawal sleeves also conforms to industry-accepted standards.
