Engineering calculators (Beta)
Resolve one applied load on a two-support shaft into radial bearing reactions and product-coefficient equivalent loads.
Click the grid to add ordered vertices. Edit coordinates in mm; separate holes with a blank line. The last vertex closes to the first automatically.
Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.
Reference calculation only. Results do not certify suitability for an actual design or its safety.
Inputs: select a blue symbol to edit Results: red-orange values and lines
3D shows an illustrative extrusion. Its display length does not enter the section calculations. Edit dimensions in 2D.
Ay=Fy(1−x/L); By=Fy x/L; Az=Fz(1−x/L); Bz=Fz x/L; Fr=√(Ry²+Rz²); FaA=qFa; FaB=(1−q)Fa; P=XFr+YFa.
Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.
ReferenceEquations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.
Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.
Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

2支持の軸に1か所で作用する荷重から、各軸受のラジアル反力と等価荷重を求めます。
Ay=Fy(1−x/L); By=Fy x/L; Az=Fz(1−x/L); Bz=Fz x/L; Fr=√(Ry²+Rz²); FaA=qFa; FaB=(1−q)Fa; P=XFr+YFa.
単純支持2点・1か所の集中荷重で、軸の自重は別途加えるモデルです。張出しでは一方の支持反力が反転します。軸方向の分担qは軸受配置・固定側と自由側に合わせて指定し、自動で等分しません。X・Yは軸受の種類、Fa/Fr、e、回転輪等の適用条件を製品資料で確認した値です。既定値1は操作例で、どの軸受にも使える係数ではありません。特に純アキシアル荷重や複列・組合せ軸受ではこの一般式をそのまま適用できない場合があります。寿命は得たPを既存の軸受寿命計算へ入力して別途確認します。
Resolve one applied load on a two-support shaft into radial bearing reactions and product-coefficient equivalent loads.
Ay=Fy(1−x/L); By=Fy x/L; Az=Fz(1−x/L); Bz=Fz x/L; Fr=√(Ry²+Rz²); FaA=qFa; FaB=(1−q)Fa; P=XFr+YFa.
Two simple supports and one concentrated load; add shaft self-weight separately. Overhung loading can reverse one reaction. Specify axial share q from the locating/floating arrangement, not an assumed equal split. X and Y must match bearing type, Fa/Fr, threshold e, rotating ring and the product-specific equation regime. Defaults of 1 are operating examples, not universal factors. Pure axial loading and paired/multi-row bearings may require other equations. Enter the resulting P into the separate bearing-life tool.
