C10 = Standard Preload Symbol for Metric Series
PN7B = Tighter Bore and O.D. Accuracy for SU Bearing
P4 = ABEC 7 Precision
Note: Pricing is for 1 Bearing Single, Duplex Pair = 2, Triplex = 3 Bearing Singles
This is highly rigid and accurate ball screw support bearing often used for the machine tool driving mechanism.
1 High axial rigidity
Uses many balls, and set high contact angle at 60 degrees.
2 Small friction torque
Friction torque is smaller than that of tapered or cylindrical roller bearing. This contributes to
accurate rotation by a small driving power.
3 Axial play is pre-adjusted
Combination bearings are already adjusted to a suitable preload. Universal combination bearing
(SU) furnishes certain preload for all combinations
(DB, DF, and other).
4 Simple mounting structure
A duplex combination of bearings can receive axial
and radial loads. Therefore, the installation
structure is simpler than when both a thrust bearing
and a radial bearing are used.
5 Easy handling
Inner and outer rings are inseparable, and are easy to handle.
6 Superb polyamide resin retainer
Uses polyamide resin retainer which is superb to
friction and furnishes high precision rotations.
