Sliding door guide rollers – Set of 2 nylon rollers 30 × 40 mm for sliding door rails

【No deviation from the track】: Installing our roller track can help your gate stay aligned during manual opening and closing or electric gate operation, thanks to the "extended" nylon rollers mounted on the axle, which roll freely and allow your gate to slide smoothly. 【Material】: This nylon swivel roller is made of nylon with a very strong and dense structure, offering stable performance and a long service life. 【Structure includes】: An internal body and a nylon tread for smooth rotation. Nylon is a strong material that resists impact, abrasion, and high and low temperatures. It is also resistant to chemical agents. It is the best replacement for wheels when they are worn or damaged. Suitable for electric gates, sliding gates, etc. 【Good Performance】: Our nylon olive guide is made of sturdy steel with strong load-bearing capacity, good elasticity, high toughness, no deformation, wear-resistant, corrosion-resistant, and so on. The outer surface of the bearing is smooth, which can reduce noise generated by the sliding friction of the iron door. It can be used indoors and outdoors.
