Blickle FTH 70 x 20mm Polyurethane Guide Roller - 25mm Bore

The Blickle FTH 70 x 20mm is a premium German made polyurethane roller designed for applications that need low rolling resistance, high wear resistance and reliable guidance with better cushioning than a hard nylon roller.

The Blickle Extrathane® polyurethane tread has a hardness of 92 Shore A, providing low rolling resistance with very good abrasion resistance and high resistance to cuts and tear propagation. The non-marking tread also provides better noise reduction and surface protection than harder roller materials while remaining highly resistant to many aggressive substances.

The Extrathane® tread is cast directly around a sealed 6205 2RS ball bearing, creating a compact construction with a strong chemical bond between the polyurethane and bearing assembly. This variant has a 25 mm axle bore and 15 mm clamping length.

FTH guide rollers are particularly well suited to gates, lifts, sliding and guidance systems, swimming pool covers, machinery and other equipment where a component needs to follow or control a defined path. The polyurethane tread makes them particularly useful where some vibration damping, reduced operating noise or additional surface protection is desirable without sacrificing precise guidance.

Blickle engineers, manufactures, and tests its products in Germany under exceptionally tight production tolerances. The FTH series combines Blickle Extrathane® polyurethane with quality sealed ball bearings to provide consistent running characteristics across repeated cycles. Blickle's manufacturing systems are certified to DIN EN ISO 9001, ISO 14001, ISO 45001 and ISO 50001.

The FTH 70x20/25-15K has a load capacity of 150 kg for obstacle-free applications. The Extrathane® tread is suitable for operating temperatures from -20°C to +70°C, temporarily up to +90°C, with reduced load capacity above +40°C.

The FTH 70x20/25-15K is best suited to applications where low rolling resistance, excellent wear resistance, quieter operation and improved surface protection are required from a compact guide roller. Compared with the harder FPO nylon series, FTH provides a more compliant running surface while retaining the durability required for industrial guidance systems.
