Specification Brand : QXYJLCN BulletPoint1 : 【Two sizes of screw rods provided】: This screw-rod-type leveling caster thoughtfully offers two screw sizes, namely M12 - 1.75 x 33mm and 1/2“- 13 x 1.299”. These two specifications are designed to adapt to mechanical equipment of different standards. Equipment under the metric system often adopts the M12 specification. Its specific pitch of 1.75 and length of 33mm ensure a precise fit when the caster is connected to the equipment, resulting in extremely high stability after installation. For equipment that follows the imperial tradition, the size of 1/2“ - 13 x 1.299” can achieve seamless connection, avoiding installation problems caused by differences in screw sizes BulletPoint2 : 【Superb load-bearing capacity】: Each caster can bear a load of 550 pounds, and a set of 4 casters can support a total load of 2200 pounds. Even in the case of inclination or uneven force distribution, these casters can still withstand a maximum load of 1100 pounds BulletPoint3 : 【Easy to adjust】: The casters adopt a universal wheel structure and are equipped with a smooth bearing system, enabling them to achieve 360-degree free rotation and move easily, which greatly improves the handling efficiency. These casters feature a brand-new handle design, making height adjustment very simple and convenient. Operators can easily and precisely adjust the height of the casters by turning the handle, effectively compensating for the unevenness of the ground BulletPoint4 : 【Sturdy and durable】: This caster is made of high-quality raw materials. The screw rods and brackets are made of high-strength alloy steel, possessing excellent anti-deformation ability and wear resistance. The wheel body is mostly made of high-quality rubber, which is not only wear-resistant but also can provide good shock absorption BulletPoint5 : 【Wide range of applications】: Our industrial casters can be used both indoors and outdoors and are suitable for workbenches, furniture, shelves, trolleys, laboratory equipment and so on BulletPoint6 : NOT compatible with: 0.75" diameter shelving poles/posts for model no.

It provides two screw sizes, M12 - 1.75 x 33mm and 1/2“ - 13 x 1.299”, specially designed to fit different standard equipment. For metric equipment, the commonly used M12 specification, with its 1.75 pitch and 33mm length, enables a precise and highly stable connection between the caster and the equipment. For imperial equipment, the 1/2“ - 13 x 1.299” size can achieve seamless connection, making it easy to install both new and old equipment. Secondly, super load-bearing capacity. A single caster can bear a load of 550 pounds, and a set of four can support 2200 pounds. It is effortless to move heavy-duty machine tools and fully-loaded storage racks. Even when tilted or under uneven force distribution, it can withstand a maximum load of 1100 pounds, fully ensuring the safety of equipment transportation. Thirdly, convenient and user-friendly adjustment. It adopts a universal wheel structure and smooth bearings, achieving 360-degree free rotation and making it easy to move in narrow spaces. The new handle design makes height adjustment simple and precise. Operators can finely adjust the caster height according to the ground undulations by turning the handle. Even on rugged sites such as outdoor construction sites and old factory workshops, it can ensure that the equipment remains level, preventing faults caused by tilting and material spillage, and ensuring the smooth progress of the work process. Fourthly, sturdy and reliable quality. With excellent material selection, the screw rods and brackets are made of high-strength alloy steel, which is resistant to deformation and wear. The wheel body is mostly made of high-quality rubber, which is wear-resistant and shock-absorbing. Fifthly, wide applicability. It can be used both indoors and outdoors. In factories, it facilitates the movement of workbenches; in office spaces, it enables flexible rearrangement of furniture; in logistics warehouses, it helps racks to be easily repositioned; in commercial stores, it allows trolleys to move around smoothly; in scientific research laboratories, it ensures the smooth movement of experimental equipment. It is suitable for various workbenches, furniture, racks, trolleys, laboratory equipment, etc., meeting diverse needs.
