FR Series Types & Specifications

Available in different sizes, sealing configurations, clearance, materials, and lubrication options to meet operating requirements.

Bearing Steel

Bearing steel (typical GCr15) is a special high-carbon chromium steel for bearing rings and balls, featuring uniform high hardness, great wear resistance and rolling contact fatigue strength.

Stainless Seel Bearing

Stainless steel bearings are made of stainless steel material and have excellent rust and corrosion resistance, suitable for low-speed to medium speed operation in humid and mildly corrosive environments.

Ceramic Bearing

Ceramic bearings are made of silicon nitride ceramic balls paired with steel or ceramic rings, which are lightweight, insulated, heat-resistant, and corrosion-resistant, suitable for high-speed, lightweight, and insulated working conditions
