Product Description:
The K351 line of 2000kg caster is a special tow cart casters that need very flexible and accurate steering. They are capable of handling very heavy loads and include a high precision swivel raceway, thus providing very flexible, silent rotation with excellent wear resistance, hence continuous operation is allowed.
The swivel raceway uses a bearing combination of a thrust ball bearing and a tapered roller bearing, thus resulting in high precision, very smooth rotation, and noise-free operation. The legs are welded ones; by changing the thickness of the raceway and leg materials, a bracket can be made to have the designed service strength. A zinc plating/sealing of the bracket metal surface has been done, and the salt spray resistance can go up to 76 hours. The bracket's maximum load capacity goes up to 2000 kg, thus it meets the requirements that the equipment with highly flexible steering needs, and it can also support powered towing applications.
Benefits of High Capacity Caster:
Caster steering under 2 tons of pressure is no longer a problem:
Thrust ball bearings and tapered roller bearings are combined in this design. The problem with difficult caster steering has thus been completely solved. The very low starting resistance greatly reduces the instantaneous load on the traction vehicle or AGV motor, motor overheating and wear are prevented, and the power system's service life is greatly extended.
Impact-Resistant Welded Structure, Ensuring Safety Under Extreme Loads:
The bracket legs use a reinforced welding process, and the material thickness is dynamically reinforced according to the 2000kg load requirement.
76-Hour Salt Spray Resistance, Fearless of Harsh Working Conditions:
High-standard electroplated zinc sealing has been done for the metal surface, and in salt spray testing, the duration has been 76 hours. So, it is suitable for shipbuilding factories with very high humidity, mechanical workshops that are metal dust contaminated, or places where anti-rust is strictly enforced. As a powered traction tool, specifically designed for "powered chassis":
It is known that the eccentricity of the rotation has been optimized for automated powered traction. Thus, it guarantees excellent tracking and flexibility for the heavy-duty carts while moving at high speed or turning, thus preventing skidding and excessive swaying.
K351 Industrial Wheel Selection Guide:
Material Options:
PX (High-strength polyurethane with cast iron core):
[Heavy load preferred] The single wheel width is only 76mm. It can bear the pressure of 2 tons and at the same time,
protect the floor. In addition to oil resistance, it has very good shock absorbing and low noise properties
which are suitable fora precision environment like the automotive industry
NX (High-strength reinforced nylon):
Features lighter weight and lower rolling friction. Resistant to strong chemical corrosion, suitable for concrete floors or extremely smooth surfaces, ideal for achieving maximum starting efficiency.
Wheel Diameter Strategy:
150mm / 200mm:
Low installation height. Under a 2-ton load, it can ensure the stability of the center of gravity.
250mm / 300mm:
Strongest obstacle crossing capability. When there are workshop joints or debris etc., even in the worst cases, the extra-large wheel diameter ensures smooth movement and reduces the vibration of the cargo.
