High percision cup and cone german roller bearing 31310Tapered Roller Bearing

Specifications

Taperroller bearings' inner and outer rings and rollers of taper roller bearing with the vertex is on the line at a point, inside and outside the ring is a separate type. Single row taper roller bearings can bear combined load with radial load and axial load. Taper roller bearings in the design of a special case when that is designed with international interchangeability, that is, a group bearing are the same model, both an outer ring of any one with a roller mounted to the inner ring, and they would not be affect the bearing of the using results. 
There are double row and four row taper roller bearings. Taper Roller Bearing Cage size is a small steel plate stamping molding, use a larger size made of brass or soft steel turning, while is used for heavy duty, then use bolt-shaped cage. 
Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity. This kind of bearing is separable bearings, according to the number of rolling bearings’ rows can be divided into single row, double row and four row taper roller bearings. Single row taper roller bearing clearance adjustment required to the user during installation; double row and four row taper roller bearing clearance from the factory has been given based on user requirements, users do not need to adjust it.
Taper roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. The surface of the projection lines of all tapered bearing axis in the same point together. This design makes taper roller bearings particularly suitable for bearing complex (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle increases, the higher the axial load capacity. Angle size of the computational coefficient e to represent; e the higher the greater the contact angle, and the greater the bearing axial load applicability. 
Taper roller bearings are widely used in automotive, mill, mine, metallurgy, plastic machinery and other industries.

Specifications Of  taper roller bearing 31310  

Tapered roller bearing is designed in such a way that cone paexes of inner ring raceway,outer ring raceway and roller raceway intesects at one point of its central line.Beside metric series products,there are inch series products,which are applicable for heavy load and impact load.

Single row tapered roller bearing

It can bear simultaneously radial load and single row axial load.

When carrying radial load,it creates axial thrust load.Thus two bearings are configured (or combined)face to face or back to back.

According to contact angle difference,it is classified into three types:small come angle, medium cone angle and big cone angle.
