carbon steelIt is characterized by its low price and not asking too much for applications,so it is highly appreciated by the vast number of merchants. It is widely used in household appliances, electrical tools, pneumatic tool , textile machines,medical instruments,sport equipment,office furniture, packing machine, fishing gear,toys,sliding doors and windows,etc.
High – carbon steels are being called the" hard ",which possess excellent wear resistance ,strength ,rigidity, good elastic and fatigue limit(especiallythe notch fatigue limit).
Medium- carbon steel has higher rigidity but lower deformation and toughness compare with low- carbon steel.
Low- carbon steel It is characteristic of low strength and rigidity,good deformation and toughness.
Chrome steel Chrome steel has feature of tensile.fatigue,wear resistance , high rigidity and great toughness.It can meet the requirements of corrosion and high – temperature resistance under certain conditions.
Vacuum degassed Chrome steel GCR15 is a type of standard material for producing accurate inner ring,outer ring and ball.This material is in conformity with the specifications of AISL 52100(America),DIN100Cr6(German) and JISSUJ2(Japan).As there are less interferences from impurities, significantly extending the life span and effectively improving the bearing’s torque and noise reduction property.
Stainless steelCompare with the ordinary Chrome steel,the Stainless steel has more advantages such as it has great rigidity and better rust and corrosion resistance.Work environment: getting appropriate lubricants,shields,etc.It
can be used in -60°C~+300°C.
CeramicsHeat ,wear, corrosion resistant, insulated,anti – electromagnetic, anti – moisture , high rotation speed,etc.Especially it is to the atrocious conditions. The contexts of usage is cover various fields, aviation, voyage,oil, chemical,car,electronic equipment,textile,medical equipment,instruments,toys,etc.
Bearing ringDimension tolerance , geometric tolerances,and surface quality of bearing’s working surface will influent the operating noise.YCZCO adopts precision CNC machining ,to dimension precision, geometrictolerances , design drawing , mold making , grinding,cleaning, assembly ,testing,every link of strict checks.Which is to ensure all our products
are tested by our strict criteria.
Ball The balls evenly with by the cage,often make rolling movement
between 2rings.The shape,size and number will directly influent bearing’s load tolerance and operating capabilityWe use high precision, small vibration steel ball.It’s surface must be strengthened,no bumps scratches, lacerations, pitting and notch.
CageEnclose and move with all or part of the balls.It also be used to insulate the balls,
guide the balls’movement and to improve lubrication performance inside the bearing.,etc.
YCZCO’s cage is commonly made of cold rolling carbon steel.But in the corrosiveness environment ,nonparallel or high – speed situation,stainless steel,engineering plastics cage
can be decided on request.
ShieldYCZCO’s shield,taking the carbon steel material, if necessary,
taking stainless steel or other material.
SealYCZCO adopt different kind of seal material to meet the requirement of their
operating in high temperature and being compatible with grease. Acrylonitrile-butadiene r
ubber is our standard material.but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
GreaseThe shield and seal were filled with standard grease.We can use different
grease as request.
Bearing precisionThese deep groove ball bearing precision have been graded according to the standard .The precision is increase from the left to right in the form below.
Radial clearanceThe inner ring’srelativedistance move in the axial direction.Deep grove ball bearing is divided into 5group according our nationalstandards GB/T4604-1993.The radial clearance haveanimportanteffect on the bearing operation, noise ,adiabatic expansion and theamplitudeof the vibration.
Vibration and vioceVibration and voice of the bearing are divided into Z,Z1,Z2,Z3,Z4, instruments,it can be measure by S0910-1 instruments.If special requirement,BVT-1 instruments can be used to divided it into V,V1,V2,V3. Data appearing as follows.
The maximum vibration acceleration of a single bearing.
