Available options include roller diameter 38 mm (1.5 in) with shaft 12 mm (1/2 in) and roller diameter 50 mm (1.5 in) with shaft 12 mm (1/2 in). - Durable Stainless Steel Unpowered Rollers (Heavy-Duty): Made from stainless steel for waterproof, rustproof, and warp-resistant performance. Supports goods up to 41 kg (90 lbs). These powerless rollers move by the weight of the carried object, reducing mechanical failures and maintenance costs. - Spring Press-in Mounting: Spring installation makes assembly easy. Push the spring in or pull it out from the opposite side to securely install the roller into the conveyor frame. - Versatile Uses and Compatibility: Suitable as replacement rollers or as conveyor rollers for roller stands in woodworking, saw stands, material stands, boat rollers, and dock rollers. When used with suitable brackets, they can support a range of heavy-duty applications and may even be used in other DIY setups, including cat/dog fence solutions. - Use Scenarios: - Replacing worn rollers on a woodworking saw stand or roller stand in a home workshop. - Creating a gravity-driven conveyor section to move crates or materials up to 90 lbs. - Using as boat dock rollers or trailer rollers for smooth movement in marine or heavy-duty outdoor settings.
