The Alpha is a fixed caster designed for stationary load support and directional stability in material handling applications. The caster features a rectangular plate fitting that provides secure mounting to equipment and furniture bases. The housing is constructed from heavy steel sheet, ensuring robust structural integrity and durability under demanding operational conditions. The wheel assembly comprises a 3.94 inch diameter wheel body manufactured from plastic thermoset material with heat-resistant properties, offering reliable performance in temperature-sensitive environments. The wheel tread is identical to the wheel body material, providing consistent rolling characteristics and wear patterns throughout the wheel's operational life. The wheel is equipped with a dry bearing bush that facilitates smooth rotation while minimizing maintenance requirements. The overall height of the caster assembly measures 5.04 inches, accommodating standard equipment clearance specifications. The caster demonstrates a static load capacity of 661.39 pounds, supporting substantial stationary loads without deformation or failure. The dynamic load capacity is rated at 330.69 pounds when the caster is in motion at speeds up to 2.49 miles per hour, ensuring safe operation during equipment repositioning and transport. This combination of materials, bearing technology, and load specifications makes the Alpha fixed caster suitable for industrial, commercial, and institutional applications requiring reliable mobility and load support.
