LYC has begun manufacturing slewing bearings since 1970s. The long history help LYC accumulate rich design and manufacturing experience. LYC is the largest manufacturing base of slewing bearings in China. Slewing bearings used for radar tracking system high-precision machine tool rotating floor medical appliance wind power generators port machineries and engineering plant etc. The outside dimension of slewing bearings is up to 6.25m (the biggest at present). The rotating accuracy is up to class p5.

Rolling mill bearings are high-accuracy bearings used for accuracy sheet rolling mills. The dimensional accuracy and rotating accuracy of rolling mill bearings are required up to class P4 and P2. Besides the mutual difference of depth of section is required highly too. Sendzimir high-accuracy rolling mill bearings manufactured in mass can completely satisfy customer’s requirements. What’s more the using life can surpass the life of products with the same type manufactured by other developed countries.

The using life load carrying capacity and shock resistant ability of sealed four-row tapered roller bearings used in mill rolls are very long and high. According to different working condition and environment LYC designed various sealing equipments to protect bearings from hazardous substances which make the using life of the bearings obviously longer than those open bearings without seals. LYC has the proprietary intellectual property rights of sealed four-row tapered roller bearings used in mill rolls.

Split bearings can take the place of solid pedestal. Split bearings can be used in appliances which are difficult to mount or dismount and inconvenient to repair. They are widely used in metallurgical machineries paper manufacturing machineries and large scale equipments.
LYC can provide customers split bearings with various structures.

Since 1997 LYC had begun to research and develop series of bearings used by wind power generators such as pitch bearings yawing bearings main shaft bearings and gear box bearings etc. Those bearings produced by LYC are with high load carrying capacity long using life (20 years) highly reliability excellent antiseptic property and resistant shock ability etc. They can rotate flexibly and stably. LYC has a history of 10 years of manufacturing bearings of wind turbines. LYC is the creator of the standards for wind turbine bearings.

LYC has 50 years of history to design and manufacture main shaft bearings. The boring lathe main shaft bearings B3-706 B3-707 were awarded a quality gold medal which indicated the highest level of manufacturing bearings in China.

Rotary table bearings of YRT series are combination bearings with high accuracy high rigidity high load carrying capacity and low frictional moment. Bearings of YRT series can carry radial loads bidirectional axial loads and titling moments. They are suitable to be applied in rotary applied table chuck milling cutter measurement and trail installations.
