| 1 Dimensions Programme (dimension plan) including Rolling Dimension systems or listed . 2 Bearings (bearing series) of a specific type of rolling bearing , with increasing size , in most cases, there is a certain relationship between the contact angle of the same size and shape . 3 series or a combination of the width dimension series (dimension series) height and diameter of the series of series of tapered roller bearings include angle. For more information, please refer to the size of the program and the series >>> 2 . Bearing Dimensions 1 Dimensions (boundary dimension) defining the shape of a one-size bearings , the basic dimensions of the inside diameter , outside diameter, width ( or height ) and chamfer dimension . 2 bearing diameter (bearing bore diameter) radial bearings or thrust bearing inner ring inner diameter of the inner diameter of the shaft . 3 . Bearing outside diameter (bearing outside diameter) to the outer diameter bearings or thrust bearing seat outside diameter. 4 bearing width (bearing width) defines an axial distance between the two ring face width between the radial bearing , for single row tapered roller bearings is the axial distance between the back of the back of the outer ring and the inner ring . Size 3 . Sub-components and parts A distance ball diameter (ball diameter) and tangential to the surface of the ball between two parallel planes . 2 the diameter of the rollers (roller diameter) distance ( radial plane) tangential to the surface of the roller parallel to each other between the two tangents in the plane perpendicular to the axis of the roller . When calculating the rated load , the application roller central radial plane . 3 roller length (roller length) contains the distance , including the roller ends between two radial plane . But " roller length" in the calculation of rated load with a theoretical maximum length of contact roller and the raceway at the shortest exposure . 4 . Dimensional tolerances associated with 1 nominal diameter (OD ) (noninal bore diameter) (outside diameter) surface of the envelope theory basically cylindrical bore ( cylindrical outer surface ) of the cylinder diameter. Specified in a radial plane , the envelope diameter of the cone surface of the conical hole theory . Theoretical diameter of the spherical envelope surface of the substantially spherical surface. 2 rings nominal distance between the two theories face width (nominal ring width) between the bearing rings . The actual width deviation is usually a reference value ( basic dimensions ) . 3 . Bearing nominal width ( bearing height ) (nominal bearing width) (bearing height) distance between the two theories ferrule end face ( gasket on the back ) between radial bearings for limited width ( thrust bearing height ) . Usually bearing the actual width or height deviation of the actual bearing the reference value ( basic dimensions ) . |
