- Absence of key grooves on the hub and shaft helps improve more strength
- on its parts.
- This can save energy and space for high torque transmission.
- Much more transmission can be obtained regardless of how large the
- product is.
- Easy adjustment of axial direction can improve operator's work efficiency.
- DR300& DR300C have common types compatible with other products.
- DR300F can be used without any flange designed.
- If DR300(C) is combined on a multi row, DR300EF type (adjustable) can be
- recommended. |

- Surface roughness : Rt max16㎛
- Processing tolerance(Max) :
- d : 40mm Below : Shaft : h6, Hub : H7
- d : 42mm More than : Shaft : h8, Hub : H8 |

- Adjustments can be made such as interlocking with the hub (for example, h7 on the shaft / H7 on the hub side).
- There are 2 types in terms of axial direction when assembled, whose features must be fully understood.
- If the hub moves with the product assembled, there must be enough space in front or back of the hub.
- If there is no or insufficient space, the product can be difficult to disassemble or it can have low transmission torque.
- It is recommended that the hub and the axis be treated with heat.
- Lack of axial strength can result in low transmission torque and the ring being fixed on the shaft.
- Be sure than larger screw holes must be placed on the flange than the bolts used to assemble the product.
- The bolts can be selected, small in size and many in number, but less than the standard torque.
- DR300F can be applied on the flange as follows.
- Though DR300F can be used on a multi row, check the strength of a hub, clamped torques and bearing pressure more closely.
- Also, transmission torques will not be multiplied in proportion to what the sheets are used. Take care. |
