Heavy and light equipment hard to match with the same casters? PU wheels offer multiple hardness options for greater flexibility!
PU casters can be customized across a range of hardness levels (Shore A 60–95), allowing you to match softness or firmness to different load requirements: lower hardness is ideal for light-duty equipment (e.g., office chairs), while higher hardness suits medium-duty applications (e.g., industrial trolleys). No need to source separate casters for different equipment—PU wheels seamlessly adapt to diverse usage scenarios.
