FFPJ

Features

・The very best Oldham's coupling (large size).
・Combines a S45C hub and cast slider : all-metal Oldham's coupling.
・Minimally-sized slider gap covered with a high viscosity resin grease to prevent seizure and eliminate backlash.

・Features a high-speed rotation greese resupply mechanism.

1. Due to grease limitations, standard thermal resistance is 150℃ or below.

2. This coupling is a high-precision, high-rigidity coupling, so the parallelism of the shaft is especially important. If there is declination then every 90° there will be rotation resistance,

    producing rotational vibration and noise.

3. The amount if eccentricity must also be kept at a minimum for high-speed rotation.
