The ERV series of linear actuators expand on the ER family and bring an external bearing design, which spreads the bearing span and increases the overall load capacity. The ERV is an extremely rugged and industrially hardened linear actuator utilizing the same roller wheel technology as the industry leading HPLA and HLE products. The bearing wheels are pre-loaded to eliminate play in the system and strategically located along the carriage to evenly distribute load across the length of the carriage.
