Stainless steel rollers Constructed from stainless steel for rust resistance and water exposure. These rollers are smooth, durable, and built to withstand demanding environments. They operate quietly and with minimal vibrations, supporting smooth and efficient conveyor movement. Spring mounting design Spring installation mechanism enables easy assembly. To install, simply push the spring in or pull it from the opposite side to securely mount the roller into the conveyor frame. This spring-based mounting reduces setup time and simplifies maintenance. Low noise operation The unpowered roller does not require electric drive. Its inherent friction and the sliding interaction of transported items produce minimal noise, contributing to a quieter, more comfortable working environment. Movement remains stable and reliable, with quiet operation. Please confirm the required roller size, frame, width, and roller center measurements before purchase. Use scenarios - Production line transfer: Move heavy components between stations without relying on powered rollers, reducing energy use and maintenance. - Packaging and sorting areas: Stage and relay goods with low noise to minimize operator disruption during operations. - Warehouse or workshop transfer zones: Create a maintenance-free section of a conveyor that handles high loads with quiet, steady performance. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
