621/612 - Timken Taper Roller Bearing - 2.125x4.75x1.625inches
Product Description
Single tapered roller bearings have an outer ring, the inner ring and a set of tapered roller cover from the box-type cage into an inner component. Outer and inner components separated in accordance with ISO tapered roller bearings dimensions standards, tapered roller bearing outer or inner ring assembly of any of a standard model and the same model should be able to outer or inner components to achieve international exchange. That is the same model, except the outer portion size, tolerances must comply with ISO492 (GB307) provided, the inner components of the cone angle, cone diameter components must also comply with the relevant provisions of interchangeable.
Typically, a single row tapered roller bearing outer ring raceway of the cone angle at 10 ° ~ 19 ° before, can withstand the combined effects of the load-bearing and radial loads. Cone angle the greater the axial load-bearing capacity is also greater. The large cone angle of the bearing, postcode plus B, cone angle between 25 ° ~ 29 °, it can withstand greater axial load. In addition, single row tapered roller bearing clearance can be resized during the installation process.
Double row tapered roller bearings outer ring (or inner) is a whole. Two inner (or outer) face similar small, middle spacer, clearance by the spacer thickness is adjusted, it can also be used to adjust the thickness of the spacer double row tapered roller bearings preloaded.
