QWhat is Tapered Roller Thrust Bearings ?

AThe Tapered Roller Thrust Bearings belongs to the separate type of bearing, and the inner and outer rings of the bearing have conical raceways. This type of bearing is divided into separate, double and four-row conical roller bearings according to the number of columns of the rollers installed. A single cone roller bearing can withstand radial and single axial loads. When the bearing is subjected to radial load, an axial splitting force will be generated, so another bearing that can withstand the opposite axial force is required to balance.

QWhat is the cylindrical roller bearing characteristics?

AThe cylindrical roller is in contact with the Raceway and has a large radial load capacity. It is suitable not only for bearing heavy loads and impact loads, but also for high-speed rotation. Cylinder roller bearing raceways and rolling bodies are geometrically shaped. After the improved design, the new structure design with higher load-bearing capacity, baffle and roller end surface not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions of the contact area between the roller end surface and the edge, and improves the performance of the bearing.

QHow to adjustment of cylindrical roller bearings Radial clearance?

AThe commonly used methods for adjusting the radial clearance of the fully loaded cylindrical roller bearings are as follows: 1, The side gap of cylindrical and elliptical axle tiles can be adjusted by manual scraping or by trimming and scraping in the bearings. 2, The top gap of cylindrical and elliptical axle tiles can be adjusted by manual scraping or when circumstances permit. 3, for the multi-oil wedge fixed shaft tiles, in principle, scraping and adjustment of the shaft tile gap are not allowed, and new tiles should be replaced when the gap is not appropriate. 4, for the multi-oil wedge tiltable shaft tiles, no repair is allowed to scratch the tile, the gap should be replaced due to the gap. For tiles with adjustable thickness, the amount of tile can be adjusted by adjusting the bottom of the tile with stainless steel pads, or by reducing the thickness of the tile. Note that the thickness error of the same block should be less than 0.01 mm for the tiltable shaft tiles with many oil wedges.

QWhat's the difference between single row bearing and double row bearing

ARegarding the specific difference between single and double row angle contact ball bearings, first of all, single row angle contact ball bearings can only withstand axial loads in one direction. When such bearings are subjected to pure radial loads, because the rolling body load line and the radial load line are not in the same radial plane, the internal axial separation force is generated, so they must be installed in pairs. 1. Single row corner contact ball bearing Single row corner contact ball bearing has the following structural forms: The code name of this type of bearing is S70000. There is no lock on the outer ring Raceway and it can be separated from the inner ring, holder, and ball assembly, so it can be installed separately. Most of these micro-bearings with an internal diameter of less than 10mm are used in devices with higher requirements for dynamic balance, noise, vibration, and stability such as gyro rotors and microelectric motives. 2. Double row corner contact ball bearings Compared with two-way thrust ball bearings, this type of bearing has a high limit speed, a contact angle of 32 °, a good rigidity, and can withstand large overturning moments. It is widely used in the front wheels of cars(some models also use the same size). Double row conical roller bearings). There are four structural variants of double row corner contact ball bearings: the standard design of type A bearings with an outer diameter less than or equal to 90 mm. There is no ball gap, so it can withstand equal bidirectional axial loads.
