SBFG is a selflubricating, fibre-reenforced PTFE-layer which is applied in a bushing, made of regular low carbon. As an alternative (e.g. for soft or sensitive shafts/ houses), can also be applied to a body of bronze
SBFG bushing can be produced as plain bushing, flangebushing, washer or sheet.
Areas of use
- SBFG is a bushing made for really heavy loads (also alternating load pressure) w. slow movements.
- SBFG is vibrant-resistant and insensitive to edge-pressure.
- SBFG is to be considered in those applications where Your normal PTFE, wrapped bushings don´t last or are worn out too quickly. Static friction and dynamic friction are almost identical.
- The sliding surface itself consists of a specially produced glassfibre-weave, woven together with PTFE-weave through a unique method. The weave is then seamed together with the steel/bronze-body, enabling the bushing to carry enormous loads without any of the layers getting separated. Through its unique PTFE/fibre-layer, SBFG is also able to handle corrosive environments (most chemicals etc.).
- SBFG can also be produced with a body of stainless-, acid-resistant steel or with bronze. SBFG is an excellent, priceworthy, selflubricating solution for applications exposed to heavy pressure and abrasion under low speed or oscillating movements
