clutch bearing
CKA type (basic) one-way wedge overrunning clutch
Features and applications:
CKA type is a basic wedge overrunning clutch. Bearings can be installed as needed to withstand axial and radial loads. The one-way self-locking is reliable and the reverse release is light. It is suitable for the limit speed of 800-2500r/min and the nominal torque: 31.5-4500N.m. Commonly used in packaging machinery, printing machinery, food machinery, medical machinery and various bucket elevators, conveyors, textile machinery and other mechanical drives.
CKB type (B200 series without inner ring type) one-way wedge overrunning clutch
Features and applications:
CKB type, namely the foreign B-type 200 series, is a wedge-type overrunning clutch without inner ring and bearing support. The shaft is directly installed in the clutch. Therefore, the shaft used for clutch installation needs to be hardened to HRC58-62 after grinding, and the taper of the shaft should not exceed 0.01mm per 50mm. In order to ensure the concentricity of the shaft and the outer ring of the clutch and bear the radial or axial load of the outer ring and the shaft, bearings can be installed on both ends or one end of the clutch. It is suitable for the limit speed of 1000-2400r/min and the nominal torque: 60-1250N.m. Commonly used in mechanical transmission such as packaging machines, bag making machines, corrugated paper production lines, reducers, elevators, electric drums, etc.

Features and applications:
CKD type overrunning clutch is a wedge type overrunning clutch with key grooves on both ends of the outer ring without bearing support. When in use, it needs to be installed with bearings to withstand axial and radial loads. The radial dimensions are the same as the standard dimensions. The inner ring and the shaft are connected by a key, and the two ends of the outer ring have stop grooves for fixing the outer ring and the frame to transmit torque. It is suitable for the limit speed of 800-1500r/min, and is often used in packaging, printing, food, textile, light industry and other machinery.
CKZ type (bearing type) one-way wedge overrunning clutch
Features and applications:

It is suitable for backstops with a limit speed of 600-1500r/min, a common nominal torque: 180-8000N.m, and a maximum torque of 70,000N.m. Commonly used in packaging machines, lifting and transporting machinery, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, cement machinery, power stations, etc., also known as backstops.
CKF type (non-contact) one-way wedge overrunning clutch
Features and applications:
CKF type is a non-contact one-way wedge overrunning clutch with bearing. It uses the centrifugal force of the wedge and the special geometric relationship between it and the outer ring to achieve “transcendence” transmission. When the speed of the inner ring reaches 310-420r/min, the wedge does not contact the inner and outer ring raceways. Wearing operation, reliable reverse stop. It is suitable for the ultimate transfer speed: 400-1500r/min, and the nominal torque is: 400-2500N.m. It is often used with reducers for transportation machinery, hoists, metallurgical machinery, mining machinery, cement machinery, high temperature fans, power station equipment It is generally used for medium and high-speed transmission.
CSK type (KK type) one-way overrunning clutch
Features and applications:
CSK series wedge-type overrunning clutch is also called rotating ball bearing, and its external dimensions are the same as 62 series deep groove ball bearings. (Except CSK40) It is a combination of deep groove ball bearing and wedge clutch, and its interior has been filled with grease. The seal can prevent dust above 0.3mm from entering the interior. Torque is transmitted by a close fit method. The outer ring is press-fitted with a rigid frame with N6 tolerance, and the inner ring is press-fitted with the outer diameter of the working shaft. When installing, pay attention to not knocking the inner ring to press the outer ring into the frame, and not knocking the outer ring to press the inner ring into the shaft outer diameter. The transmission torque is small (7.4-260N.m) and the limit speed is high. It is widely used in the transmission of printing machinery, packaging machinery, food machinery, electric rollers, reducers and testing equipment.
HF type drawn cup needle roller clutch
Features and applications:
The stamped outer ring needle roller clutch is an alien wheel clutch. The needle roller is the locking element. It is composed of a thin-walled stamped outer ring, a cage, a special-shaped spring embedded in the cage, and a locking element roller needle installed in the cage. The special-shaped spring keeps the needle roller close to the accuracy. Often used in printing machinery, packaging machinery, textile machinery, food machinery, household appliances, light industry machinery and testing equipment, etc. The common torque is 0.34N.m-121N.m, which is suitable for high speed, generally 3900-34000r/min. The hardness of the shaft used by the user to select this clutch must reach HRC58-62, and the dimensional accuracy and shape tolerance must meet the requirements.
HFL drawn cup needle roller clutch and bearing assembly
Features and applications:
The stamped outer ring needle roller clutch is an outer planet wheel type overrunning clutch with needle bearings. In the middle is a needle roller clutch, and a needle roller bearing is placed at each end. The needle roller is the locking element. The locking accuracy is high, and the free travel angle is small. In order to transmit larger torque, two clutches can be applied side by side. To withstand a certain amount of pressure. Commonly used in printing machinery, packaging machinery, food machinery, light industry machinery and testing equipment, etc.
NF type non-contact backstop
Features and applications:
NF type non-contact backstop is a clever use of the centrifugal force of the special shape wedge and its special geometric relationship with the inner and outer rings to realize its forward movement. The main components are non-contact and wear-free operation. A new type of backstop device capable of backstop. The backstop is widely used in transportation machinery, hoists and other mechanical equipment with backstop requirements. The product has great backstop efficacy and high reliability. It has the advantages of long service life, light weight, convenient installation and maintenance, and its comprehensive performance is obviously better than other backstops. On the basis of the NF backstop, we have developed Phoenix (NFX, NFA, NFB, NFC, NFD, NFE, NFF) backstops to meet the needs of users with different functional requirements.
CFL type overrunning clutch with elastic pin coupling
Features and applications:
CFL type is an integrated product of overrunning clutch and elastic pin coupling. There are several wedges distributed in the raceway in this overrunning clutch. The working surface of the wedge is connected with the shaft extension of the high-speed driving device of the host, and drives the wedge assembly to rotate synchronously. The half body is connected with the low-speed shaft extension of the low-speed drive device of the host. When the main engine rotates at a higher speed, the intermediate shaft of the high-speed driving device drives the inner ring and the wedge assembly to rotate together. The wedge and the inner surface of the outer ring slip, and the inner ring and the outer ring rotate relative to each other. When the speed reaches or exceeds the non-contact speed of the clutch, due to the structure and the special shape of the wedge, the wedge is out of contact with the outer ring surface to achieve frictionless non-contact rotation.
This product has advanced structure, reliable work, large carrying capacity, high efficiency and long life. It is widely used in coal mine, metallurgy, chemical industry, building materials and light industry as a single-machine two-speed drive switching device.
CKS type two-way wedge overrunning clutch
Features and applications:
CKS type two-way wedge overrunning clutch, one end of the shaft hole is connected to the driving shaft, and the other end of the shaft hole is connected to the driven shaft. When the outer ring does not move and the driving shaft rotates clockwise or counterclockwise, the driven shaft also rotates synchronously. When the driven shaft is under the action of external torque, it cannot rotate clockwise or counterclockwise. It is often matched with a ball screw pair or other components, as a mechanism to prevent reversal, and can also be used alone as a precise positioning, torque transmission or cut-off torque transmission. Used in the mechanical transmission of printing machinery, packaging machinery, lifting and transporting machinery, various non-standard equipment and experimental benches.
