When the rotary help bearing is working, the internal and outer rings recognize relative rotation thru the aggregate of rolling elements. When the exterior pressure acts on the bearing, the load is transmitted to the internal and outer rings, and is transmitted to every different via the rolling element, attaining the carrying capacity.

1. Deep groove ball bearing with dust coverDeep groove ball bearings with dust cover are divided into Z type and 2Z type. When used under environmental conditions where lubrication is difficult or lubricating oil is inconvenient, the bearing interior is usually injected with anti-rust and lubricating dual-purpose lithium based grease, and the lubrication amount is 1/4 to 1/3 of the bearing internal space.2.

This bearing adopts ceramic rolling element (ball or roller) made of Si3N4 material; It has excellent insulation performance, its capacitance is basically 40pf, and the insulation performance is better than that of coated bearings. At high temperature, the DC impedance can also reach the range of G ohms, and has good insulation performance. Ceramic rolling element has excellent wear resistance and low lubrication requirement. Especially suitable for high-speed, low friction, low temperature operation; It works well under dry friction conditions.

The insulated bearing is a specially designed bearing whose internal structure can effectively isolate the external environment and prevent conductive and conductive heat. Insulated bearings are usually used in special industrial environments or in equipment requiring special protection.Structure composition: The insulated bearing is composed of an inner ring, an outer ring, a rolling body, a cage and a seal.

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

The popular riding machine for a stud kind cam follower is a slot, for use with a flat head screwdriver. However, hex sockets are accessible for greater torquing ability, which is specifically beneficial for eccentric cam followers and these used in blind holes.

Product Description:Q195 carbon steel coil due to its good plasticity, can be used to manufacture light steel keel, can be easily processed into various shapes of keel, and can withstand a certain building load.

Stamped outer ring needle roller clutch, commonly known as one-way bearing or one-way needle roller bearing,  is a single directional bearing composed of a thin-walled outer ring, cage, spring plate,  and needle roller that is stretched from an alloy sheet. It can be used as a converter, check device,  and overrunning clutch, and is widely used in fitness equipment, cash counting machines, washing machines,  fishing gear, toy cars, and other transmission parts that need to have a reverse stop function.

Cam Follower Needle Roller Bearings are also referred to as track follower. They are designed to follow a sliding or rotating piece (cam) and they use rollers or needles as the rolling elements. Cam Follower Bearings are therefore able to replicate a specific motion because they are highly versatile. They have thick-walled outer rings that run on a track.

The working principle of the rolling bearing with seat is mainly to rely on the rolling body to roll in the groove of the inner and outer rings, and convert the input rotating force into rolling motion, so as to support and transfer the load. Compared with plain bearings, rolling bearings with seats have less friction and higher transfer efficiency because they reduce rolling friction.

The working principle of needle roller bearings is to use rolling friction to reduce friction and resistance. When the bearing is subjected to axial or radial load, the needle roller rolls between the inner and outer rings, thereby reducing friction and resistance.

Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations that can withstand heavy loads and vibration loads without difficulty. Such bearings can withstand large axial loads in a single direction, but they cannot withstand radial loads, and they have no automatic aligning capability.

Product Description:Mild steel plates have a lower carbon content, usually no more than 0.25%. The lower carbon content makes the steel have good toughness, ductility and weldability. Used in the manufacture of home appliances, such as refrigerators, washing machines, air conditioners, etc.

Product Description:The 2024-T3 Aluminum Pipe is a heat-treatable alloy known for its high strength, excellent workability, and moderate corrosion resistance.

Product Description:Cold-rolled carbon steel coil is further processed by hot-rolled carbon steel coil as raw material. It is widely used in household appliances, such as refrigerators, washing machines, air conditioners, etc.

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

Rotary support bearings are widely used in various mechanical equipment and construction machinery, such as cranes, rotary tables, machine tools, wind power equipment, drilling RIGS, excavators and so on. In these equipment, the rotary support bearing assumes the important role of supporting the rotating member, ensuring the normal operation of the equipment. At the same time, it is also widely used in high-end fields such as aerospace, ocean engineering, and automated production lines.

Product Description:Galvanized is the key surface treatment of the product, hot dip galvanized layer can effectively prevent steel rust and corrosion, improve the durability of the anti-skid in wet, corrosive environment. There are a variety of thicknesses to choose from, such as the common thickness range from 2mm-8mm to meet different load requirements.

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

Since a bearing can choose different bearing seats, and a bearing seat can choose different types of bearings at the same time, there are many varieties of bearing seats. Bearing seat is included, many large foreign bearing companies also have their own bearing seat type record. However, the same bearing housing model is not marked exactly the same in different company samples.
