Designed to axially locate spindles in both directions and typically used in conjunction with cylindrical roller bearings (N and NN series) particularly suitable for heavy axial load applications. Manufactured to SP, UP and P4C precision class with Brass and Polyamide cages.

BTM series are manufactured in a back-to-back arrangement with 30° or 40° contact angles. With a 25% lower bearing height than the corresponding 2344 series they are particularly suitable for compact designs. With lower axial stiffness and load carrying capacity butmuch higher speed capabilities. This range is also available with ceramic balls for ultra high speed applications. Also with annular groove and oil lubrication holes.

Available with 60° contact angle and large number of balls provides high axial stiffness for reasonably high speed applications.
