The Alpha is a fixed caster designed for reliable stationary wheel support in industrial and commercial 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 incorporates a 6.3 inch diameter design with an elastic tire featuring non-marking, vulcanized tread material that protects floors while providing excellent traction and wear resistance. The wheel is mounted on a precision ball bearing that enables smooth rotation and reduces friction during movement. The overall height of the caster measures 7.87 inches, making it suitable for applications requiring specific clearance specifications. The Alpha caster demonstrates impressive load-bearing capabilities with a static load capacity of 1322.77 pounds, allowing it to support substantial weight without deformation or failure. For dynamic applications, the caster maintains a dynamic load capacity of 661.39 pounds when operating at speeds up to 2.49 miles per hour, ensuring safe and reliable performance during transport and repositioning tasks. The polyamide wheel body provides lightweight construction while maintaining structural strength and chemical resistance. This combination of heavy steel housing, precision ball bearing, and durable polyamide wheel body makes the Alpha fixed caster an excellent choice for applications demanding stability, load capacity, and floor protection.
