The HRC90 Insert is the rubber spider element used in HRC 90 series couplings to transmit torque while absorbing shock, vibration, and minor misalignment.

• Natural rubber spider insert for HRC 90 couplings.
• Operating temperature: –50 °C to +50 °C
• Designed to sit between two hubs (F, H, or B types).
• Natural rubber insert delivers good damping and misalignment tolerance (up to ±0.3 mm)
