Standard design

Taper roller bearings for general use , including XRB bearings to Q specifications, have been optimized with regard to

• sliding contact surfaces of the guide flange of the inner ring

• roller end faces

• raceway contact profile.

In addition, highly accurate manufacturing processes make adjustment of the bearings against each other more reliable , which dramatically improves performance especially during the very first hours of operation.

Inch bearings

Inch taper roller bearings are designated according to the ANSI/ABMA standard.

Metric bearings that belong to the same series maintain the same relative cross section

regardless of their size. This is not the case with inch bearings. All inch bearings within a series use the same cage and roller assembly but the inner and outer rings can have different sizes and designs.

Any cone (the inner ring with cage and roller assembly) can be assembled with any cup (the outer ring) belonging to the same bearing series. For this reason the cone and cup have individual designations and can be supplied separately or as complete bearings .

The designations of the cones and cups as well as the series consist of a three to six-figure number which may be prefixed by one of the following letters or combination of letters: EL, LL,L, LM, M, HM, H, HH and EH. The prefixes characterize a bearing series from extra light to extra heavy.
