HRB crossed roller bearing series (outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. The type is well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.Identifi -cation numberMain dimensionsShoulder heightBasic load rating（radial）weightinner ring d (mm)outer ring D(mm)Roller pitch circle diameter dp(mm)width B B1 (mm)Chamfer r(min)dsDhC kNC0 kNKgHRB3010305541.5100.637477.358.360.12HRB3510356046.5100.64151.57.649.120.13HRB4010406551.5100.647.557.58.3310.60.16HRB4510457056.5100.65161.58.6211.30.17HRB.657.47216.720.90.27HRB.668821824.30.3HRB.6789219.427.70.35HRB.69111130.142.10.7HRB.445.30.75HRB..748.60.83HRB.150.91.45HRB.8120.611712712.524.10.4HRB.5150.612213623.741.50.75HRB.56HRB.2161.612714124.243.20.72HRB.7251.513316466.91002.62HRB.5150..70.72HRB.514317469.51072.82HRB..950.11HRB.515418574.81212.96HRB..50.68HRB.516419476.81283.16HRB..3HRB.6251.517320481.71353.14HRB..12.21HRB..44HRB..782.92.99HRB.21574HRB.7HRB200352247..6HRB..31714.1HRB.525628168.31454.5HRB.5252.526529069.31505HRB.5302..1HRB.7402..8HRB.531534076.31785.9HRB..4HRB.6402..2HRB.4202.536338354.11433.9HRB.3352..5HRB.4402..5HRB.71826.6HRB..52017.3HRB.8402.HRB.6502..7HRBHRB.HRB.HRBHRBHRB.
