Description
Overview:
This Knott-style trailer brake drum (MPN 211 064) is built to the 200 x 50 mm brake size used on many braked trailer axles. It provides the friction surface for 200 x 50 brake shoes and is drilled for a 5-stud wheel fixing pattern. The drum accepts five M14 x 1.5 bolts arranged on a 6.5 in (165.1 mm) pitch circle diameter, matching common Knott-pattern running gear. Supplied complete with the 42490 bearing (Maypole reference MP1815B) already fitted, it is ready for installation during axle or brake service. This pattern is widely used as a replacement on Ifor Williams trailer applications that use Knott 200 x 50 brake assemblies. Intended for competent technicians, it supports reliable braking performance on general duty, plant, and transport trailers where this specification is required.
