Welcome to our newly redesigned website!
The Alpha smart is a swivel castor designed for industrial applications. The unit features a small rectangular plate fitting for secure mounting to equipment bases. The housing is constructed from heavy steel sheet and incorporates a precision swivel bearing system utilising two ball races to ensure smooth directional movement under load. The wheel assembly comprises a polypropylene body fitted with a thermoplastic rubber tread for optimal grip and floor protection, supported by a roller bearing for reduced rolling resistance. The wheel diameter measures 125 mm. The castor has an overall height of 155 mm from mounting surface to floor contact. Load specifications include a dynamic capacity of 100 kg at speeds up to 4 km/h and a static load rating of 200 kg, making it suitable for medium-duty mobile equipment applications.
