4Pcs NTA1220 Needle Roller Thrust Bearings With Washers 3/4"X1-1/4"X4"

Description: These Needle Roller Thrust Bearings provide a high degree of stiffness within a minimum axial space. It has a smaller cross-section than a standard thrust bearing for use in restricted spaces. These bearings are designed to accommodate heavy axial loads and peak loads due to the small diameter deviation of the rollers within one assembly. NTA Thrust Bearings can be combined with washers in the TWA-series in applications where adjacent components cannot serve as raceways. Made of hardened spring steel, both faces of the washers are polished and can be used as raceways. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, elevators, rolling mills, ship rudder shafts, etc. Specification: Bearing Model: NTA1220 Bearing Washer Model: TWA1220 Needle Roller Material: Chromium Steel (GCr15) Cage Material: ST14 Steel Bearing Washer Material: 65Mn Spring Steel Inner Diameter: 3/4" Outside Diameter (D): 1-1/4" Washer Thickness: 2" Total Thickness(with Washers): 4" Dynamic Load Capacity (Cr): 8kN Static Load Capacity (Cor): 2.4kN Maximum Rotational Speed (Oil): 9500rpm Package Content: 4 x Bearing 8 x Washers
