Deep groove ball bearings are the most widely used type of rolling bearings. It is characterized by low frictional resistance and high speed. It can be used on parts with radial load or combined load of radial and axial action. It can also be used on parts with axial load. Deep groove ball bearings are available. In gearboxes,instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, 3D printing, etc.
Deep groove ball bearings are inseparable bearings, which have the advantages of no maintenance during operation, and are suitable for use in high-speed operating conditions. They are extremely widely used radial bearings. Deep groove ball bearings have a variety of structural types. In addition to general open bearings, various sealed bearings with dust cover and sealing ring structure are also available. Also available are WZZG deep groove ball bearings with snap grooves or flanges in the outer ring.
Double row self-aligning ball bearings, the inner ring has two raceways, the outer ring has a spherical raceway, the center of curvature coincides with the axis of the bearing, and has self-aligning performance. Therefore, when the mechanical bearing is bent under load or the axis of the inner ring is inclined relative to the axis of the outer ring due to machining and installation errors, the normal operation of the mechanical device can still be guaranteed. Double row self-aligning ball bearings are mainly used to bear radial loads, but they can also bear smaller axial loads while mainly bearing radial loads, but cannot bear pure axial loads. Self-aligning double row ball bearings are designed for applications with severe misalignment in mounting or shaft deflection. The concave raceway of the outer ring combined with the two rows of balls allows operation over a wide range of contact angles.
Structure & introduction
The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall.
The drawn cup needle roller bearing has the characteristics of small radial section area, large load carrying capacity, less inertia and economic manufacture. It is suitable for small section height, or when the housing bore isn't used for raceway, this type is recommended to use. The bearing is assembled into the housing bore under a certain pressure without further axial location.
The drawn cup needle roller bearing generally takes its shaft diameter as the internal raceway. However, the proper LR type inner ring can be used in accordance with application condition.
The drawn cup needle roller bearing has two structures-with retainer and with full of needles. They are divided into opened type and close-end type. The structure with retainer has the single seal ring and double seal ring. The structure with full of needles has a large load carrying capacity.
Tapered roller bearings are made up of four interdependent components: The inner ring, or cone; the tapered rollers, or rolling elements; the roller retainer, or cage(collectively known as the cone assembly); and an outer race, or cup. They are designed and manufactured to ensure that their conical rollers and raceways are arranged so that their contact surfaces converge at a common apex on the bearing’s axis. The larger this contact angle the greater the bearing’s loading capacity.
The angular construction of single row tapered roller bearings provides a high capacity for radial, axial, and combined loads.Tapered roller bearings have window-type pressed steel cage with no marking. Others types could be specifically designed on request.
FEATURES
Dimensional Stability
Long Life Even In Contaminated Lubricant
Durable Steel Cage
Typical Applications
Tapered roller bearings are used for heavy-duty, moderate speed applications. Typical applications that will benefit from these durable bearings include:
Agriculture, Construction and Mining Equipment
Various Axle Systems
Conveyance Vehicles
Gear Box, Engine Motors, Reducers
Cylindrical roller bearings are separable, easy to mount and dismount, feature more outstanding especially when they are used on bearings requiring interference fit between inner and outer rings with the shaft and housing. Cylindrical roller bearing is contacted with the revision line between the rollers and the raceway, which is of elimination of edge stress. Comparing with the ball bearings with same boundary dimensions, cylindrical roller bearings have larger radial carrying capacity. In structure, this type of bearing is more suitable for high speed rotation
Cage material:
When the outer diameter is less than (inclusive) 400mm, solid brass cage or steel press cage are adopted for single row cylindrical roller bearing. When the outer diameter is more than 400mm, brass cage and pin-type cage are adopted for four row cylindrical roller bearing.
Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load. Roller and ring guard friction small, suitable for high speed rotation. May according to the ring presence of guard, NU, NJ, NUP, N, NF, such as single row cylindrical roller bearings, double row cylindrical roller bearing and NNU, NN and other. The WZZG bearing inner ring and outer ring is separable structure.
Application
Automotive, tractor, machine tool, electric machine, water pump, cranes, elevator, agricultural machinery, textile machinery, rolling mill, mining, metallurgical, plastic machinery ect.
