Metric Design-a-bush Calculator for Industrial Applications - Beta v05 

Step 1  Fill in your dimensions, operating conditions and temperatures.  Use the units specified to avoid errors.  Enter numbers with no thousands separators and use a decimal point if required. 
Change initial values to those of your application.
Housing diameter (D)   mm Housing diameter must be > Shaft diameter
Shaft diameter (d)   mm If d>200 mm, this is a large bush, and it is suggested that your calculations and application be checked by a consultant. 
Use Customer Service below.
Bush length (L)   mm
Total mass supported (M)   kg      
No. of bushes supporting total mass (N)  

 

    
Revolutions per min (R)   rpm      
Max operating temp (Tmax)   °C If Tmax > 70 °C then please request your application to be checked by a Vesconite consultant.  Use Customer Service below.
Min operating temp (Tmin)   °C

Step 2 Check loading P =

   MPa If P > 20MPa, this is a high bearing load application.  We would be happy to check your requirements and provide additional advice. Use the Customer Service below. 
     

Step 3  Check shaft surface speed  V =

   m/min If V > 300 m/min,  have your application checked by a Vesconite consultant.  Use Customer Service below.

Step 4 Check PV =

  
MPa.m/min		 If PV <  5 MPa.m/min, initial greasing or unlubricated
 5 - 10 MPa.m/min, initial greasing required
10 - 20  MPa.m/min, regular greasing required
20 - 40 MPa.m/min, continuous lubrication required
40 - 200 MPa.m/min, operate under water.
If PV > 20 MPa.m/min, have your application checked by a Vesconite consultant.  Use Customer Service below.
 
Step 5  Machine your bush to the dimensions below. For the nearest bushing or rod size, check our stock production sizes or click for Customer Service.
Machine bush outside diameter mm  Tolerance ± mm  Includes interference fit
Machine bush
inside diameter		 mm Tolerance ± mm Includes running clearance and allowance for bore closure when press fitted.
Wall thickness mm Tolerance +0.0- mm Check your machined wall thickness is within tolerance, otherwise stacking of tolerances could lead to loss of clearance.
Bush length mm Tolerance +0.0- mm
