FAFNIR SUPER PRECISION BEARINGS FOR MACHINE TOOL APPLICATIONS CATALOG

SETTING THE STANDARD

Our products and services set the standard in high-speed spindles, ball screws, rotary tables and other demanding applications. Our portfolio includes specialized tapered roller and ball bearings produced to precision classes that deliver operating characteristics necessary for the highest performance. Timken bearings meet or exceed application needs for rotational accuracy, consistency and rigidity. Longer bearing service life translates to more machine uptime and production.

PRODUCT BREADTH

Brands like Timken and Fafnir reflect an extensive line of tapered, spherical, cylindrical, ball bearings and mounted units for virtually every machine tool and industrial application. We can offer the right bearing for almost any machine position.

TAPERED ROLLER BEARINGS

Timken tapered roller bearings have been used for many years in machine tool applications due to their widely recognized advantages in stiffness, load-carrying capacity, precision and reliability over other bearing designs. As applications have achieved much higher cutting speeds, Timken has maintained the same global accuracy level by developing optimum spindle designs through special internal bearing geometry and innovative bearing designs.

BALL BEARINGS

Ultra-precision equipment requires more than standard bearings can deliver. Timken super precision ball bearings meet the highest industry standards in tolerance levels (including ABEC 9). Designed for machine tool applications, our precision ball bearings offer superior tolerance and performance.

ANGULAR CONTACT BEARINGS

Timken Fafnir angular contact ball bearings are manufactured to provide a high degree of rigidity in both axial and radial directions while operating at minimum temperatures for a wide range of speeds and operating loads, leading to more accurate work at a higher production rate. Our angular contact ball bearings give the machine builder the flexibility required to meet speed and load variations in machine tool applications.

BALL SCREW SUPPORT BEARINGS

Ball screw support bearings with steep contact angles, available in single row, or in housed units, provide high levels of stiffness and simplified installation for the demands of servo-controlled machinery.

ASSEMBLE-TO-ORDER PROGRAM

Our premium customer service is leveraged by our global sales and distribution network. The Assemble-To-Order Program can perform cost-effective quick delivery of a variety of machine tool ball bearings for product not easily found at local distribution centers.

HOW TO USE THIS CATALOG

We designed this catalog to help you find the Timken bearings best suited to your equipment needs and specifications. This publication contains dimensions, tolerances and load ratings, as well as engineering sections describing fitting practices for shafts and housings, internal clearances and other bearing features. For more information, please use the Timken Engineering Manual (order no. 10424). It provides valuable assistance in the initial consideration of the type and characteristics of the bearings that may best suit your particular needs.
