2)as  customer requirement

Our packing is strong enough and safe for transport and shipment.

Shipment

Transportation of goods may take place by road railwayair or combined ways, etc.

The mode of transportation depends on you as long as it is convenient for you.

3.Bearing structure

Bearing ring Dimension tolerance, geometric tolerances, and surface quality of bearing’ s

working surface will influent the operating noise. YCZCO adopts precision CNC machining ,

to dimension precision,  geometric tolerances , 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 movementbetween 2 rings. The

shape, size and number will directly influent bearing’s load tolerance and operating capability 

We use high precision, small vibration steel ball. It’s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.

Cage Enclose 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 cagecan be decided

on request.

ShieldYCZCO’s shield, taking the carbon steel material, if necessary,taking stainless steel or

other material.

Seal YCZCO adopt different kind of seal material to meet the requirement of their operating in

high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.

Grease The shield and seal were filled with standard grease. We can use differentgrease as request.

4.How to choose bearings?

Usually these factors should be considered: the bearing size and direction of the load, the

nature of the bearing load, self-aligning performance requirements, bearing rigid requirements, bearing performance requirements, the speed of the bearing working environment temperature requirements and some other aspects such as the requirement of bearing axial winding,

restrictions on the size of bearing appearance, installation and dismantling is convenient, the requirement of the bearing seal and the friction torque, vibration and noise, etc.

7.About material

Carbon steel is steel in which the main interstitial alloying constituent iscarbon in the range of 0.12–2.0%. The American Iron and Steel Institute (AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified orrequired for chromium, cobalt,molybdenum, nickel, niobium, titanium, tungsten,vanadium or zirconium, or any other element to be added to obtain a desired alloying effect;
