Roller Bearing press roller type, is divided into: cylindrical roller bearings rolling body is cylindrical roller bearings, cylindrical roller ratio of length to diameter of less than agricultural bearings or equal to 3; needle roller bearings rolling body is needle bearings, needle length to diameter ratio greater than 3, but a diameter less than or equal to 5mm; tapered roller bearings rolling body is tapered roller bearings; spherical Roller bearings eleven rolling body is spherical roller bearings. (3) whether the bearing aligning their work is divided into: 1) aligning bearings raceway is spherical shape, able to adapt to angular deviation and angular movement between the two raceways of Full complement cylindrical roller bearings the bearing axis ; 2) non-aligning bearing (rigid bearing) able impedance path between roller bearing axis angular offset. (4) according to the number of rows of rolling elements bearings, divided into: 1) single row bearings has a list of rolling element bearings; 2) double row bearings have two rows of rolling element bearings; 3) multi-row bearings with more than two rolling element bearings, such as three, four bearings. (5) whether the separation bearing their part, are divided into: 1) separable bearings bearings with separable components; 2) can not be separated Thin section bearings after the final bearing bearing supporting rings are freedom can not be arbitrarily separated bearings. (6) bearing their structure and shape (if no filling slots, without inner and outer rings and structural shapes, ribs, and even whether the cage, etc.) can also be divided into a variety of structural types.
