Conveyor Components Size Checking before Shipping

As an important component of the conveyor system, the daily inspection of the idler support directly affects the operational stability and service life of the equipment. The inspection work needs to be approached from multiple perspectives, and specific standards should be formulated in combination with actual usage scenarios. It is necessary to take into account not only the performance parameters of the bracket itself but also its matching situation in the entire machine. The following are common testing items and operation norms.

Visual inspection is the first step. The surface of the bracket must be free of cracks, burrs, sharp edges, and all welding points must be evenly filled. There should be no false welding or missed welding. The bolt holes at the connection parts of the brackets need to be inspected for deformation. If the deviation of the hole positions exceeds 0.5 millimeters, they need to be repaired, as well as the thickness of the paint film.

Dimensional accuracy directly affects the installation effect. Use a vernier caliper or tape measure to measure the center distance between the installation holes at both ends of the bracket. The allowable error range is within +/-1.2 millimeters. The overall flatness of the bracket needs to be checked with a level. The straightness deviation should not exceed 2 millimeters per meter. Special attention should be paid to the height difference of the bracket's bottom feet. If the height difference of the four support feet of the same group of brackets exceeds 3 millimeters, it will lead to uneven force distribution.

Material quality inspection requires checking the steel material certificate to confirm the use of Q235 or higher grade carbon structural steel.
