Special Four Contact 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 Special Four Contact 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 Special Yaw Bearing for Wind Generator 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.
LYXQL Four Contact Special 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 Special Yaw Bearing for Wind Generator----Surface treatment:
1: black surface treatment
2: Surface sandblasting and painting
3: Surface chrome plating
4: Surface spray zinc treatment
5: Surface phosphating treatment
6: Dacromet treatment
LYXQL Four Contact Yaw Bearing for Wind Generator--- Seal
The sealing of the cross roller slewing bearing without teeth is mainly to prevent the filled grease from leaking out, and also to prevent external dust, impurities and moisture from entering the inside of the bearing and affecting the normal operation of the bearing.
Since most of the slewing bearings work under heavy loads and low speeds, the sealing form of the bearings adopts two structures: rubber seal ring seal and labyrinth seal. The rubber sealing ring itself has a simple structure, small space occupation and reliable sealing performance. The disadvantage is that it is prone to early aging under high temperature conditions and loss of airtightness. Therefore, under high temperature conditions, the slewing bearing should adopt a labyrinth seal. In addition, the material of the sealing ring under high temperature is high temperature resistant fluoro rubber.
LYXQL 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,
