Tapered roller bearings taper inner ring and outer ring have groove, tapered roller are arranged in between. All of the surface of the cone of lines in the projection of bearing the same point axis together. This design make circular cone roller bearings is especially suitable for bear composite (radial and axial) the load. The bearing axial load ability is the contact Angle α of the decision; Larger Angle α, axial load capacity is higher. Angle size by calculating coefficient e to say; E value is, the bigger the contact Angle is, the bigger the axial load bearing of the greater the applicability.
Tapered roller bearings are usually separated model, namely the belt roller and maintains a component of the inner circle ,circle of inner cone components and cone outside (outer) can apart installation.
Tapered roller bearings widely used in automotive, rolling mill, mining, metallurgical, plastic machinery, etc.
Being located at Hangzhou Bay New District of Ningbo City, our factory owns 25 automatic production lines of pricision bearings in micro size and mini size, which can lower the cost to the greatest extent. At the same time, we have the most convenient transportation. There is only 12 km to connect the Grand Hangzhou Bay Bridge, only 50 km from Ningbo and 120 km from Shanghai. That these make it available to offer the most competitive price.
2. High quality.
According to dimension tolerances and runout accuracy, DDP deep groove ball bearings grades are as ABEC-1, ABEC-3, ABEC-5, ABE-7, ABEC-1 is standard grade, while ABEC-3, ABEC-5 much higher and ABEC-7 the highest.
There tolerance grades corresponds in respect to those of precision adopted by the International Standard Organization (ISO 492).
