Excellent TIMKEN machine tool bearings (2)

The advantages of Timken ^Â® Fafnir ^Â® ball screw support bearings (MMN/MMF series) are as follows:

Advantage 1 : Longer service life - the pair of low-torque integral seals resists impurities and extends bearing life in demanding operating environments. The bearings are lubricated prior to packaging and can be relubricated during use.

Advantage 2 : High load capacity - The double row design supports axial and bidirectional loads. The internal raceway space allows for more balls to accommodate load carrying capacity. Consistent preload for precise repetitive positioning - precise positioning of the bearing's double inner and outer rings and the cage by using a precision locknut on the shoulder to achieve precise preload.

Advantage 3 : Ultra-precisionâ€”ABEC 9/ISO P2 axial running tolerance reduces runout and improves positioning accuracy. Strictly controlled width tolerances and smooth running torsion improve system stability and performance.

Advantage 4 : Stronger hardnessâ€”The bearing combines a 60 degree contact angle with maximum ball holding capacity for superior axial stiffness and precision.

Advantage 5 : Higher speed - Heavy duty NLG1#2 lubricant provides excellent speed performance. Ceramic balls and specialty lubricants are available to dramatically increase speed and acceleration levels.

Advantage 6 : Simple and flexible installation â€“ whether it is a fixed nut or a rotary nut design, the integral bearing unit with built-in seal simplifies installation. The flange unit does not require external clamping.

Advantage 7 : No need to grind end caps (MMN) - strict width tolerances (5 times higher than the ABEC 9/ISO P2 standard) and markings made in the width of each bearing row eliminates the need for end cap grinding. Increased productivity while reducing assembly costs.
