Mountings / Load and Deflection P1Y Series

Figure 13 shows the maximum allowable moments for Figure 14
each of the three types of loading: Bending, Radial, and
Cross moments. Max. Allowable Max. Unsupported
Load [L] N (Lbs)
The sum total of each of these types of moments, divided by Bore Length mm (in)
each of the maximum values, determines a Load-Moment Single Double at Max. Load
Factor (LMF) should be equal to or less than 1.0. On Carriage Carriage
horizontal mountings, the total load (L) should also be 25 289 (65) 578 (130) 1015 (40)
divided by the maximum load allowable (Figure 14) and 32 534 (120) 1068 (240) 1140 (45)
factored into the equation. 40 800 (180) 1600 (360) 915 (36)
Horizontal Mountings:
Acceptable length and load combinations for the various
bore sizes can be determined from the charts in Figure 15.
Vertical Mountings:

mid-support, see the graphs on the next page.
