Neutral - 30216/DF | Matched Tapered Roller Bearings | 80 × 140 × 56.75 mm

Details

Neutral 30216/DF is a matched tapered roller bearings with inner diameter 80 mm, outer diameter 140 mm and width 56.75 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is a double-row tapered roller bearing predominantly engineered for heavy-duty industrial applications requiring high radial stiffness and bi-directional axial load support. Consists of two single-row cups (outer rings) facing each other, often featuring a precision-ground intermediate spacer ring. This layout gives the bearing high systemic stiffness and accommodates thermal expansion cycles in structural shafts. Material : The standard is high-purity, vacuum-degassed GCr15 Chrome Bearing Steel, with case-carburized alloy steel available for shock-loaded applications. Features are : Integrated Oil Groove & Lubrication Holes, Logarithmic Contact Profiles, Low Friction & Super-Finished Raceways, High-Volume Static & Dynamic Ratings, Acoustic & Vibration Dampening, Extended Fatigue Limit. Applications : Machine Tool Spindles, Mining and Quarrying Equipment, Construction and Tunnel Boring Machinery, Agricultural Equipment, Marine & Offshore Engineering, Energy & Power Generation, Heavy Material Handling. DF=Matched Bearing Pair Arranged Face-To-Face. A Figure Combination Immediately Following The DF Identifies The Design Of The Intermediate Ring.
