The SIMPLEX nylon insert (series 3208) with its hardness of approx. 73 Shore D is an extra hard insert. This white polyamide insert offers outstanding impact qualities and is guaranteed to combine maximum strength with unique durability. It is composed of extruded and extremely homogeneous material. Compared to injection moulded plastic inserts, it is therefore considerably more wear-resistant and durable and will never chip even in sub-zero temperatures. Moreover, it is also oil and grease resistant. This insert is available in sizes ranging from D30mm to D80mm.
