Pulley characteristics: The adjustable range is 5 mm.
High and low temperature range - 30 to 170 C
Repeated start-up and shut-down life test 150,000 times.
(Standard 100,000 times) Load 100 kg static load up to 120 kg of high-quality aluminum, shell support using high-quality stainless steel, pulley overall anti-corrosion performance is high (NSS 240 hours or above 9 grades, usable 8-10 years) using motor bearings, high load-bearing, smooth sliding, smooth hand feel, silence less than 25 decibels (high material hardness HRC 66 degrees) imported modified nylon, pulley coating using imported modification. Nylon material, high strength, strong wear resistance, high impact resistance, self-lubricating effect, excellent anti-aging performance
When it was first used, it was very smooth, but after a little time, the sliding door creaked, which was not smooth. Where is the problem???? It's not about the design of the Steinless steel track pully manufacturers, it's not about the door structure. When the door leaf is used, it is stuck and can't be pushed. Maybe there is a problem with the pulley. As an important part of the whole sliding door function, pulley is perfect or not. Many sliding doors have no problems when they are first used, but with the use time becoming longer and longer, the problems appear from time to time,,, inevitably, on the market, pull roller for sliding door There are many kinds of pulleys for manufacturers, but there are not many pulleys with strong load-bearing performance, smooth and durable, silent. Baogao hardware is used as a sliding door track pulley supplier - 150000 times of opening and closing life test at 30-170 ℃, with a static load of up to 120kg. The temperature limit is far beyond the requirements of the world. Reasonable design, easy installation and adjustment. Z3 low noise bearing, Z3 represents that the vibration acceleration level limit of the bearing conforms to Z3 group specified in relevant standards. Z1 / Z2 / Z3 group bearings belong to low noise bearing. Z3 has lower noise than Z2, and Z2 has lower noise than Z1.
