Full Ceramic Self Aligning Ball Bearings 1004  20 x 42 x 12 mm PTFE Cage

Full Ceramic Self Aligning Ball Bearings have a spherical outer ring raceway, balls and cage continue to rotate.   this type of bearings is suitable when the displacement of the centers around which the shaft and housing rotate and shaft deflection are likely to occur.  dimensions of the bearing is ID 20mm x OD 42mm x 12mm (width). Bearings are made of Ceramic. Item: Full Ceramic Self Aligning Ball Bearings Item Name:1004 Size: 20mm x 42mm x 12mm Dimensions: 20*42*12 mm/Metric ID (inner diameter)/Bore=20mm OD (outer diameter)=42mm Width/Height/thickness=12mm Quantity:One Bearing.

Ball Bearings

Ball Bearings main function is to minimize the friction caused by any relative movement of two or more objects, in order to reach the maximum efficiency of energy usage, we aim to minimize the "converted to heat" energy by using Ball Bearings.
A great variety of Ball Bearings types and Ball Bearings designs are known, the manifolds of the ball bearings is justified by their various purpose of the ball bearings needed application, each type of ball bearings has a certain characteristic technical properties, rolling ball bearings have the following advantages compared with the plain bearings:

• Low starting moment.
• Low friction at all speeds.
• Low energy consumption.
• High reliability.
• Small width.
• Low consumption of lubricant.
• Long relubrication intervals.
• Easy to mount and dismount.
• Standardized dimensions.
