PU screw iron brake casters
Bearing selection for industrial casters: Bearings are also called rolling bearings, including: roller bearings, needle bearings and ball bearings. The main difference is that the roller bearing is used for occasions with large radial pressure; the needle bearing is suitable for occasions with large radial pressure and small rotating speed; the ball bearing is suitable for occasions with small radial pressure and high rotational speed.

Product Detail
Bearing selection for industrial casters: Bearings are also called rolling bearings, including: roller bearings, needle bearings and ball bearings. The main difference is that the roller bearing is used for occasions with large radial pressure; the needle bearing is suitable for occasions with large radial pressure and small rotating speed; the ball bearing is suitable for occasions with small radial pressure and high rotational speed.
In the case of the same size and almost the same speed, the radial load cylinder is larger than the axial load of the ball shaft; the cylinder generally bears the axial load in the opposite direction or does not bear the axial load (the individual models can withstand the biaxial axial load), generally Used in the free end of the shaft; the ball bearing can withstand the bidirectional load used at the fixed end. It can also be said that the same brand, the same lubrication, the same bearing capacity, the life of the cylindrical bearing is greater than the ball bearing.
Tip 3: Injection wheel and casting wheel
Injection molding wheels and casting wheels are the most common and commonly used ones. The difference in molding is still very large. The main differences are as follows:
1) Injection molding is injection molding into physical molding, and casting molding is chemical reaction molding.
2) Injection molding has a large pressure on the mold, and the casting molding has a small pressure on the mold and a low requirement on the mold.
3) Casting can flexibly change the formula to produce different products.
Tip 4: Industrial caster material
There are mainly nylon casters, cast iron casters, high temperature resistant casters, rubber casters, super artificial rubber casters, polyurethane casters and other common materials. In these materials, we focus on the characteristics of thermoplastic polyurethane elastomers (TPU) in polyurethane materials.
Characteristics of TPU polyurethane:
TPU polyurethane material has the hardness and high mechanical strength similar to ordinary thermoplastic plastics. It can be produced by plastic processing method. At the same time, it has the elongation, resilience and compression deformation recovery properties of general elastomers. With TPUR's high tensile strength and elongation at break, especially excellent tear resistance, flexibility and wear resistance, it can be used to prepare various resistances used in many fields such as automobiles, footwear, electrical appliances, and sports. Grinding and shock absorbing parts.
