The Alpha smart is a swivel castor with total lock, designed for demanding industrial applications and equipped with a small rectangular plate fitting for secure mounting to equipment and machinery. The housing is constructed from heavy steel sheet material and features two ball races within the swivel bearing assembly, ensuring smooth rotation and reliable directional control whilst maintaining the total lock functionality for stationary positioning. The wheel comprises a 125 mm diameter design with a solid rubber tread in black, mounted on a roller bearing to facilitate smooth operation and extended service life. The castor achieves an overall height of 155 mm, making it suitable for integration into various equipment configurations and spatial constraints. With regard to load capacity, the castor supports a static load of 200 kg, whilst the dynamic load capacity is rated at 100 kg when operating at speeds up to 4 km/h, and 100 kg at speeds up to 3 km/h, allowing for flexible deployment across different operational scenarios. The combination of heavy-duty steel sheet housing, precision ball race swivel bearing, and robust rubber-tyred wheel ensures durability, stability, and reliable performance in demanding industrial environments where both mobility and secure locking are essential requirements.

Swivel castor 125 mm
Alpha smart
3370DVR125P62

The Alpha smart swivel castor is a robust mobility solution engineered for demanding industrial applications, featuring a small rectangular plate fitting that ensures secure and straightforward installation to equipment and furniture bases. The housing is constructed from heavy steel sheet material and incorporates two ball races within the swivel bearing assembly, providing smooth rotational movement and exceptional durability under continuous operational stress. The wheel comprises a 125 mm diameter design with a sheet steel body and is fitted with a roller bearing for reliable performance, whilst the tread surface utilises solid rubber in black, delivering excellent grip, floor protection, and extended service life across various floor types. The overall height of the castor measures 155 mm, making it suitable for applications requiring compact vertical clearance whilst maintaining stability and manoeuvrability. This castor demonstrates impressive load-bearing capabilities, with a static load capacity of 200 kg, enabling it to support substantial fixed weights without deformation or performance degradation. For dynamic applications, the castor maintains a load capacity of 100 kg at speeds up to 4 km/h in one direction and 100 kg at speeds up to 3 km/h in the other direction, ensuring reliable performance during transport and repositioning tasks. The combination of precision engineering, high-quality materials, and thoughtful design makes the Alpha smart swivel castor an ideal choice for facilities requiring dependable mobility solutions with superior load handling and longevity.
