Heavy Duty Pitch Yaw Bearing for Wind Generator
Luoyang Xinqianglian Slewing Bearing Co., Ltd. ( Hereinafter referred to as the LYXQL) founded in 2003, is located in the ancient capital of nine dynasties Luoyang in Henan province. LYXQL is a national key high-tech enterprises and become a GEM listing company successfully on July 13,2020 (stock code "300850").
LYXQL Pitch Heavy Duty Yaw Bearing for Wind Generator have to bear a large overturning moment, and some of them are exposed, and are vulnerable to pollution such as dust, water mist and freezing. Therefore, surface anti-corrosion treatment meeting the whole service life shall be carried out. Equally important is the sealing technology to prevent the leakage of lubricating grease inside the bearing and the invasion of external impurities.
LYXQL Pitch Heavy Duty Yaw Bearing should bear the impact load caused by uncertain wind force. Pitch Yaw Bearing have the characteristics of intermittent work, frequent start and stop, large transmission torque and high transmission ratio. Therefore, the yaw bearing requires small clearance; Compared with yaw bearing, pitch bearing bears larger impact load and larger vibration transmitted by blade, so it is required to have zero clearance or small negative clearance to reduce fretting wear of rolling working surface.
When the wind speed is too high or too low, the pitch system changes the attack angle of the air flow to the blade by adjusting the blade pitch, so as to change the aerodynamic torque obtained by the wind turbine and keep the power output stable. The yaw system has two main functions: one is to make the wind wheel track the wind direction; Second, due to yaw, when the cable leading out of the cabin is wound, it will be released automatically.
LYXQL Pitch Heavy Duty Yaw Bearing------Technical Data:
1. Material: 42CrMo, 50Mn
2. Precision: P0. P6. P5.
3. Outside diameter: 500~25000mm
4. Cage/retainer: Nylon or aluminum
5. Gear type: non-geared, internal gear and external gear, gear hardened

LYXQL Pitch Yaw Bearing for Wind Generator------Packaging Details:
Step 1: Covered with the anti-rust oil
Step 2: wrapped with the plastic film;
Step 3: Packed with Kraft paper and professional belts;
Step 4: Put into wooden box to avoid the rust or the moist;
Remark: Normally, plastic film+ Kraft +belt+ wooden box, but customized packing available,
