Angular Contact Ball Bearing

Matched Pair Angular Contact Ball Bearings

EPT supplies matched pair angular contact ball bearings with 2, 3, and 4 single bearing combinations. The combinations available for the fixed end of spindles are usually two rows (DB, DF, DT), three rows (DBD), and four rows (DBB) sets. Matched pair bearings are manufactured assets, so a given preload is automatically obtained when they are mounted adjacent to each other.

As one of the angular contact ball bearing manufacturers, suppliers, and exporters of mechanical products, We offer angular contact ball bearing and many other products.Please get in touch with us for details.

DB matched Pair: Back-to-back Arrangement.

Axial loads in both directions and radial loads can be carried. Since the distance between the effective load centers is large, this type is suitable if moments are applied. However, if the accuracy of housing is not enough and there is a misalignment in the spindle, internal loads of bearings could be significant enough to cause premature failure due to greater moment stiffness.

DF matched pair: Face-to-face Arrangement.

Compared with the DB type, the distance between the effective load centers is small, so the capacity to carry moments is inferior to the DB type. On the other hand, this type is suitable for use with housings that have less accuracy or more considerable shaft deflections due to the low bending stiffness of the shaft.

DT matched pair: Tandem Arrangement.

Axial loads in one direction and radial loads can be carried. Since the axial stiffness of this type is twice the value of a single row type, this arrangement is used when the axial load in one direction is heavy.

DBD matched pair: 3 rows Arrangement.

Axial loads in both directions and radial loads can be carried. However, the preload distribution to each bearing is not equal, and preload on the counter side (single side) is twice that of another side. Consequently, this type is unsuitable for high-speed operation because of the significant increase of internal load of the single side, which could lead to bearing failure.

DBB matched pair: 4 rows Arrangement.

Axial loads in both directions and radial loads can be carried. In conditions with the exact axial clearance as the DB arrangement, preload and stiffness are twice that of the DB arrangement. Also, the permissible axial load of a 4-row account is more significant than that of a DB arrangement.

Universal matched pair:

EPT supplies universal matched pair angular contact ball bearings that have the same amount of stand out on both the front and back face. This means that when bearings with the same reference numerals are combined, they have the specified amount for each standard preload.

For universal combination bearings, the “V” combination marks on the outer diameter surface of the outer ring prevent “direction1′ mistakes, ensure correct matching when mounted, and indicate the direction of the contact angle.
