SME-SB / SME-LSB

SME Series (Ball Chain Type)

SME-SB / SME-SV Type (Heavy Load)
All dimensions are same as SME-SA except the mounting hole dimensions of carriage are different and the height is lower, which do not change the basic loading rating.

SME-LSB / SME-LSV Type (Ultra Heavy Load)
All dimensions are same as SME-SB and SMESV except the length is longer, which makes it more rigid.
