High-precision tapered roller bearings consist of carefully matched components that offer an added degree of fine-tuning in the bearing setting and adjustment procedure to maximize customer machine productivity. Timken manufactures high-speed designs with a variable preload capability for optimum performance. Timken also manufactures Precision Plus bearings – having an overall radial runout less than a single micron.

Our precision cylindrical roller bearings for screw drives feature a combination of axial cylindrical rollers and radial needle rollers. This unique configuration helps manage loads from multiple directions during highspeed operation. Several designs are available to accommodate varying screw drive designs.

For applications where rotational accuracy, consistency and rigidity are critical, Timken has the solution – Timken^® precision cylindrical roller bearings for rotary tables, indexing and vertical mill heads.

Precision crossed roller bearings (TXR) are designed to offer the highest levels of rotational accuracy and rigidity while conserving space and saving material costs. The bearing features two sets of races and rollers brought together at right angles with alternate rollers facing in opposite directions. This allows two half-rows of rollers to fit into the space of one. The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.

Able to withstand high overturning moments, the crossed roller bearing is ideal for the table bearing of machine tools, including vertical boring and grinding machines. It is uniquely suited to many other pivot and pedestal applications where space is limited or the lowest possible center of gravity of a rotating mass is required.

Our broad line of Timken^® Fafnir^® ball screw support bearings includes single- and double-row designs with a variety of mounting configurations. We offer flanged and non-flanged series for both standard and rotating nut mountings. Housed cartridge and pillow block units facilitate bolting to machine tool surfaces.

Angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions.

Our deep groove ball bearings deliver reliable performance in a wide range of applications and conditions. With super-finished raceways and controlled geometries, our premium design helps ensure consistent quality. Our portfolio includes standard, thin section, narrow, wide and miniature and extra-small deep groove ball bearings that span 3 mm to 400 mm bore sizes. The extended product line includes a complete offering of open, shields, seals and snap ring combinations.

Deep groove ball bearings are frequently used in electric motor applications to minimize vibration and noise. To meet our long-standing electric motor quality guidelines we designed in:

• Super finishing on raceways to reduce friction
• Preferred clearance designation (C3)
• Premium grease for high performance, low torque and less noise
