• Adopt high-strength cast steel raw material, equipped with integrated reinforcing ribs, strong bearing capacity, not easy to bend or crack under long-term vibration and impact.
• Stress relief annealing treatment eliminates casting internal stress, greatly reduces the risk of delayed cracking after long working hours.
• CNC machined mounting holes and positioning surfaces, accurate hole spacing, bolts fit smoothly, convenient installation and positioning.
• Surface sandblasting and anti-corrosion paint treatment, effectively isolate dust, water vapor and coolant splash, slow down rust and oxidation.
• OEM contour and hole layout, fully consistent with original installation base, no on-site modification required, shorten maintenance time.
• Reasonable structural design, reserved gap between bracket and pipeline, avoid direct friction between metal bracket and rubber hose.
• Excellent shock absorption and load-bearing performance, restrain pipeline swing, reduce fatigue damage of connected hoses and bent pipes.

FAQ 

Q：What signs mean the bracket needs replacement?
A：Visible crack on bracket body, fracture of reinforcing rib, serious deformation, mounting hole elongated by vibration, paint peeling and deep rust corrosion affecting structural strength.

Q：What should be noted during bracket installation?
A：Clean the mounting base before installation; align mounting holes and fasten bolts evenly with proper torque; check pipeline clearance after installation. Do not over-tighten bolts to cause bracket deformation.

Q：What are common causes of bracket damage?
A：Long-term cyclic vibration fatigue; heavy stone impact hitting bracket; bolt loose leading to hole abrasion; paint peeling and subsequent rust corrosion; excessive tightening torque during installation.

Q：Can cracked bracket be repaired and reused?
A：Not recommended. Welding repair will change the material internal stress, cracks may expand quickly under continuous vibration. Replace new bracket directly once cracks appear.

Q：How to inspect bracket during daily maintenance?
A：Check bracket surface for cracks, deformation and rust before heavy-load operation. Inspect tightness of fixing bolts. Focus inspection on reinforcing ribs and mounting holes, these areas are most vulnerable to fatigue damage.

Q：What failures will a failed bracket cause?
A：Broken or deformed bracket cannot fix pipeline firmly, leading to pipeline swing, friction wear of hoses and bent pipes, eventually causing coolant leakage and engine overheating.
