Product Description

Wholesale/ best quality/ high speed/ Needle bearing

 
Product details


   A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface.

    Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.

   Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes

About us

  Shandong Tongri Power Science and Technology Co.,Ltd is a professional manufacturer for digit-control machine tool and paper-product equipment. In 1990, we began to manufacture textile bobbin and spiral paper tube with Hao Li Factory from Taiwan in the form of joint venture. In 1992 we developed semi-automatic conical and spiral paper tube production line which is sold throughout the whole country with our advanced technology, processing method, excellent product quality and high-level service.
  In 2006, we developed QZD-68 automatic conical paper tube production line after the absorption of German and South Korean technology. The new machine is coming with mechatronics to achieve low-labor, low-consumption, high-efficiency, high-quality paper tube production.
  In 2017, we developed all new automatic conical paper tube production line-TRZ-2017 after leaning from advanced experience and improving our current model. The efficiency has been improved to a whole new level.
  We have almost 30 years machinery manufacturing and processing experience.
  We have nearly 20 years paper tube and bobbin manufacturing experience.
