Product features	90V,,.,,.The cross roller bearings are two columns of cylindrical rollers that are arranged vertically and crosswise through nylon isolation blocks in a 90-degree v-shaped roller track. Therefore, the cross roller bearings can bear radial load, axial load and torque load in multiple directions. The size of the inner and outer rings is miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity.
Introduction to the series	RA type (outer ring division type, inner ring rotation type) this series model is a compact type to reduce the thickness of inner and outer ring of RB type to the limit. Suitable for areas requiring light, compact design, such as robot and robotic hand rotation.
Series models	RA10008,RA11008,RA12008,RA13008,RA14008,RA15008,RA16013,RA17013,RA18013,RA19013,RA20013
Application field	P2.,,,,,IC,-----The precision of cross roller bearing can reach grade 2. Therefore, it is suitable for joint rotating part of industrial robots, rotary table of machining center, precision rotary table, medical machine, calculator, IC manufacturing equipment, industrial robot - precision reducer - numerical control rotary table - numerical control rotary table - detection instrument - precision medical equipment
RA7013type industrial robot with cross - roller rotary disc bearing installation and debugging
The cross roller bearing is suitable for the precise application of multi-direction bearing, such as robot arm, precision rotary table, etc.
The bearing itself is designed with negative clearance, so the bearing is sufficiently rigid to withstand large loads and has high precision (the runout is basically between 0.001mm and 0.01mm, and the bearing accuracy is above level P5).

 LYDZC Bearing

    LYDZC was founded in 2012 which insists on product quality as the principle and implements the strategy of success through quality in the process of production. We focus on manufacturing high-precision bearings.


Advanced quality idea
Taking the science and technology as our guide
Creating international well-known brand as our goal
We always provide the finest products,leading technology and excellent service to all of our customers at home and abroad to create a vast world through innovation and development.
We take the world's top bearing brands as the example.
We try to keep our products perfect when we produce every single one.

       
Strict production process
Drawings    
According to the customers specific requirements, the field where the bearing is used and working conditions. We optimize the design of products in order that the customers could economize and get their desired pruducts

materials
All the materials are high-quality bearing steel with high purity. The quality is strictly inspected and checked. The high quality of the product is guaranteed from the first procedure.
Forging
The professional forging equipment and advanced set-forging process are used.
Steel bar is heated with the medium frequency induction and its different positions temperature is measured with the thermometer. After heating and thermal hydraulic shear, they are forged in accordance with the needs of grind and expansion. Then they are groud and expanded with CNC grinding machine so that the products could meet the technological requirements in size and geometry

Heat treatment annealing
All products are produced with the spheroidal annealing to ensure the product temperature uniformity good internal structure and other characteristics which is beneficial to the next step turning and quenching.
Heat treatment with quenching and tempering
The heat treatment in strict accordance with advanced process and the precious control quenching ensure that the bright quenching effect be reached

Rough grinding
Although it is a rough grinding process,  we still strictly control the size accuracy and geometric accuracy to lay a solid foundation for the precise grinding quality

Stable tempering
We have stable tempering on the ring after the rough grinding to eliminate stress and further stabilize the size and geometric precision
Thus guarantee high-quality products

Precision grinding
The use of advanced CNC automatic production ensure that the geometric accuracy of the product reach P4 or P2


Flaw detection
Every single crack of the spare parts must be detected thoroughly to guarantee Zero Defect

Demagnetization
The residual magnetism of bearing parts is eliminated to relieve the harm to the bearings and get high-quality product
Assembling
We use automatic assembling line with online inspection of vibration noise and clearance etc and classify the quality level strictly. All these measures guarantee delivery of qualified products to customers

Spare parts
We choose steel ball ,cage ,dust cover , sealing ring , grease  ,and other parts in line with international standards to ensure our product quality


Cleaning ,  locating cleaning
drying ,  oiling , greasing  packaging  storage  and delivery
Every process is perfect and any defective product is combed out
