Chemical-resistant polymerovermolded wheels withstand harsh environments, carry loads up to 311 N, and travel up to 1.5 m/sec. Eccentric and concentric studs let users vary preload. Large thread diameters accommodate high installation torques, ensuring the wheels keep their adjusted preload value, despite vibration. Track is sold V-style for polymer DualVee and U-style for MadeWell crowned rollers. Sturdy, anodized-aluminum track comes in lengths up to 12 ft, which can be joined for longer applications. Wheel plates come in three, four, and five-wheel configurations, and in Sizes 0, 1, and 2 for both DualVee polymer wheels and MadeWell polymer crowned rollers. Wheel plates contain built-in lubricator wiper caps at both ends to clear debris and lubricate the track surface.
