Just acceptable quality: steel bracket is thin and average wheel quality. The caster is not too durable as it has only one ball bearing raceway in swivel head so if overload or by foreign force the bearing ball may fall out.

These casters are designed for heavy industrial applications where operational dependability is a must. Swivel caster models are machined from drop forged steel. With cast-iron wheel, the casters can be used in high temperature working condition.
