Reinforced steel body for durable performance - Original reinforced steel construction using SGCC galvanized steel plate and SPCC cold-rolled plate surface finished with powder material for high load bearing capability. Long-life pulley bearing and spring - Pulley bearing with stainless steel components and a very strong elastic spring. - Consists of 20% steel clamp, enabling repeated high-strength work and long service life. Three-stage locking design with roller bearings - Three-stage locking construction combined with roller bearings for secure positioning and smooth operation. Enhanced safety and high temperature resistance - Powder-coated surface on SGCC galvanized steel plate and SPCC cold-rolled plate for improved safety. - Explosion-proof and high-temperature resistant performance. Use scenarios - In industrial conveyors and belt drives in metal processing or manufacturing environments requiring high load capacity and frequent cycling. - In equipment where reliable locking and durability are needed in high-temperature or safety-critical settings. - In maintenance-heavy automation lines that demand long service life and robust protection against heat and impact.
