The index pages of Technical Reference Guide The page numbers shown in the index pages were incurrent as the information was for the previous version of the reference. 12.01.26 .
Helix hands of SBS products The helix angles for the following products were incorrect.
Product: SBS1.5-6015R, 1560L, SBS2-6015R and 1560L
35° --> 39°

Also, the data for the allowable torque was revised in accordance with the corrected helix angles.
For gears with 39°helix-hand, it does not allow you to calculate the gear strength on our Web Catalog. Please use the GCSW, the gear calculation software available for the calculation.
12.01.19 .
Diagram for B1-Shaped LM Miter Gears The tooth width shown in the diagram was incorrect and was revised as follows.There is no correction in the data for tooth width and the allowable torque shown in the dimension table.
NG corrected to --> NG

.
Web thickness for CG5-60R1 Web thickness (13) --> (14) 11.05.24 .
For SUSCP products, the values of Distance Traveled in One Turn are corrected. SUSCP5-20 200 --> 100
SUSCP5-25 250 --> 125

GC Products
The caution notes No.1 and No.3 described at "Caution on Product Characteristics"
(1) '"S" denotes minimum bore products. Inner hubs come with snap rings and set screws.
(Changed as below)
S-type products are of minimum bore products. For products with a snap ring and a tapped hole, a set screw is included as an accessory.

(3)Since Uni-chromate treatment is applied, there may be some changes in dimensions of bore, keyway etc., decreasing by a few μm..

KHG products
The caution note No.3 described at “Caution on Secondary Operations “
While cutting off the entire hub may cause curvature deformation by residual stress, some products are straightened and annealed after refining the material. --> stress relief annealed 11.04.07 .
Heat treatment for SR, SRF, SRFD, SRFK, SRO, SROS, SRH, SRHF, SRHDF, STRCPF, STRCPFD, SRCP, SRCPF, SRCPFD products. Straightened & annealed --> " - "
