Chrome Steel Taper Roller Bearing 30217 85*150*30.5 Mm For Engine Motors With Long Life
Tapered roller bearings are separable bearings, the inner and outer rings have a tapered raceway. This kind of bearing according to the number of columns loaded roller into single row, double row and four-row tapered roller bearings, such as different types of structures. Single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load, will produce an axial force component, so when you need another can withstand axial force in the opposite direction of the bearing to be balanced.
Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers arranged between the two. All conical surface projection lines in the bearing axis with a little together. This design makes tapered roller bearings particularly suitable for bear compound (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle greater axial load capacity is higher. Angle size to calculate the coefficient of e said; e larger the contact angle the greater the bearing axial load greater applicability.
Tapered roller bearings are usually separated type, that is with roller and cage assembly of inner components of the cone with tapered outer ring (outer ring) installed separately.
Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
