4.2.9 Allowable Load of Roller and Standard A Attachment
There are two kinds of allowable roller load: one is caused by load weight (Figure 4.21); the other by corner rail (Figure 4.22).
Figure 4.21 Allowable Load Caused by Load Weight
Figure 4.22 Allowable Load Caused by Corner Rail
Each manufacturer's catalog shows the allowable roller load, according to each roller type and design. Check the appropriate catalogs.
Note: The values listed for bearing roller chain and plastic roller chain are for unlubricated operation; the values for other types of chain are for lubricated conditions.
On the standard A attachment, bending load occurs from the carried load. Twisting forces may also occur, depending on the direction of the load. The manufacturer's catalog shows the allowable load for bending load.
