BS 5755:1986 pdf free.Specification for dimensions of basic features of fluid power cylinders.
BS 5755 specifies ranges of dimensions for the following basic features of hydraulic and pneumatic fluid power cylinders:
a) bore diameter;
b) piston rod diameter;
c) piston stroke;
d) piston rod thread;
e) nominal pressure.
Ratios of the effective working areas of either side of the cylinder pistons are given in Appendix A.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
4 Piston rod diameter
The piston rod diameter shall be selected from the range of diameters MM shown in Figure 1 and listed in Table 2.
5 Piston stroke
The stroke of the piston rod shall be selected from the range of strokes S shown in Figure 2 and listed in Table 3.
6 Piston rod thread
If provided, the thread at the end of the piston rod
shall be selected from the types shown in Figure 3,
and the sizes listed in Table 4.
7 Nominal pressure
The nominal working pressures of cylinders shall be selected from the pressures listed in Table 5.
Appendix A Ratios of piston effective working areas
In any single rod fluid power cylinder the effective working areas of either side of the piston is different Por convenience in calculations these areas are expressed as a ratio. Table 6 lists piston areas A and A2 corresponding to the cylinder bore diameters AL and piston rod diameters MM (isted in Table 1 and Table 2) respectively,and groups them in order of basic approximate ratios Actual ratios for each piston and rod combination are also stated in Table 6.
