Casters play an essential role in modern material handling and industrial mobility. When selecting medium-sized casters for your equipment, understanding the key features and benefits of quality casters ensures you make the right purchasing decision. Zhuoye manganese steel casters manufacturers present the 18A series polyurethane (TPU) medium manganese steel casters, a premium solution for medium-duty applications.
18A Polyurethane (TPU) Medium Manganese Steel Casters Overview
The 18A successful polyurethane (TPU) medium-sized manganese steel wheel series features a single wheel core using Taiwan-imported polypropylene (PP), with polyurethane (TPU) outer tread. This construction combines the structural strength of PP core with the performance advantages of TPU tread, including tear resistance, wear resistance, rebound elasticity, shock absorption cushioning, and exceptional durability.
Bracket Construction and Design
Medium-sized casters bracket uses high-quality iron plate, with bead plate upper and lower track using 65 manganese steel heat treatment. This makes the bracket rotation more wear-resistant, more flexible, and provides longer service life. The manganese steel construction offers superior strength and resistance to deformation compared to standard carbon steel brackets.
Bearing and Lubrication System
The grease of caster disc and bearing of 18A medium manganese steel wheel adopts molybdenum disulfide lithium grease, which possesses contact extreme pressure anti-wear performance, low coefficient of friction, and strong bearing capacity. It also provides excellent metal surface adsorption and rust resistance, wide range of working temperature, outstanding water washout resistance and corrosion resistance, good antioxidant performance, and extremely long service life.
Surface Treatment Quality
After third-party testing agency testing, 18A heavy-duty manganese steel wheel series caster surface of the spray treatment appearance grade up to 8, which is 2-4 times that of traditional caster surface electrophoresis and galvanized treatment. This superior surface treatment provides enhanced corrosion resistance and a more durable, professional finish.
Load Capacity and Available Sizes
18A successful polyurethane (TPU) medium-sized manganese steel wheels have a single wheel load range between 100-180 kilograms. There are four specifications to choose from: 2.5 inches, 3 inches, 4 inches, and 5 inches. This range of sizes makes the series versatile for various equipment types and load requirements.
Recommended Applications
In supermarkets, household, office buildings, hotels, and other medium-duty environments, choosing the 18A series of medium-sized manganese steel wheels provides more energy-saving pushing performance. These casters serve as reliable helpers in work and daily life, combining durability, quiet operation, and floor protection for a wide range of applications.
