Product Description
The 32314 (ISO/DIN designation) is a Single Row Tapered Roller Bearing with boundary dimensions of 70×150×54.5mm, manufactured to DIN ISO 355 / DIN 720 standards. Also designated 7614E (current GOST) and 7614A (original GOST), it is fully interchangeable with FAG 32314-A/32314-XL, NSK HR32314J, NTN 32314U, SKF 32314B, and Timken 32314.
With a dynamic load rating of 313–369 kN and static load rating of 380–409 kN (varying by manufacturer design optimization), the 32314 delivers robust combined radial and axial load capacity for a 70mm bore bearing. Its 2,200–4,500 rpm limiting speed (grease) enables use across a wide range of industrial and automotive applications requiring both high load capacity and moderate-to-high rotational speeds.
The bearing features key axial load calculation parameters of e=0.35, Y=1.7, Y₀=0.9, enabling precise combined load analysis for engineering applications. At ≈4.41 kg, it provides an excellent load-to-weight ratio for a 70mm bore heavy-duty tapered roller bearing.
