BearingsMiniature Bearing Types & FeaturesMiniature and instrument ball bearings can be divided into two basic types deep groove and angular contact The first (deep groove) can also be classified as "Open", "Shielded", or "Sealed" depending on the existence and type of seal or shield. Deep groove ball bearings have two inherent advantages;they can sustain some axial load in either direction as well as radial loads, and the two raceway cross-sections are simple circular arcs which can be very precisely finished so the bearings have low friction and very little noise or vibration. Several different cage designs are available with different characteristics and the choice depends upon the individual application.Model: R4ZZMetric:Inner (d): 6.35 mmOuter (D): 4.762 mmWidth (B): 4.978 mmInch:Inner (d): 1/4 = 0.25 inchOuter (D): 5/8 = 0.625 inchWidth (B): 0.196 inchGrade: ABEC-1Material: 52100 Chrome SteelSeal: Shield Qty: 1 Lot = 10 PCSModel: R4AZZMetric:Inner (d): 6.35 mmOuter (D): 4.762 mmWidth (B): 7.144 mmInch:Inner (d): 1/4 = 0.25 inchOuter (D): 3/4 = 0.75 inchWidth (B): 9/32 = 0.2812 inchGrade: ABEC-1Material: 52100 Chrome SteelSeal: Shield Qty: 1 Lot = 10 PCSModel: R6ZZMetric:Inner (d): 9.525 mmOuter (D): 22.225 mmWidth (B): 7.142 mmInch:Inner (d): 3/8 = 0.375 inchOuter (D): 7/8 = 0.875 inchWidth (B): 9/32 = 0.2812 inchGrade: ABEC-1Material: 52100 Chrome SteelSeal: Shield Qty: 1 Lot = 10 PCSWidely used in household appliances, garden machinery, outdoor vehicles, industrial production, etc. Suitable for skateboards, longboards, inline skates, scooters, robots, ship rudder axles, etc.Features: small friction, fast speed, smooth, low noise.
