-
【Size】- Bore(Inner Dia): 20mm/0.79"; Outer Diametre: 32mm/1.26"; Width(Thickness): 7mm/0.28"; Model: 6800ZZ; Dynamic load Cr(kN): 4.02; Static load Cor(kN): 2.46; Material: Chrome Steel; Accuracy class: P0; Sealed dustproof form: Double metal Shielded
-
【High Quality】- The bearings is made of bearing steel for durability and resistance to rust, corrosion and deformity under heavy loads
-
【Feature】- Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads, and it has small friction and high-limit speed
-
【Strictly Shielded】- The bearing has shield to keep lubricant in and contaminants out; protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan
-
【Application】-
Rolling ball bearings
are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, aggregate crushers, skateboards, inline skates, and scooters, among others
