Needle roller bearings are rolling pin bearings for the rotation of the needle roller bearings compared with the ball bearings, needle roller bearings with low cross-section and high load capacity characteristics; Widely used in automobiles, motorcycles, printing machinery, industrial robots And construction equipment and other industries.
IKO needle roller bearings
are rolling bearings for the elongated needle roller bearings. Compared with ball bearings, needle bearings with low cross-section and high load capacity characteristics; widely used in automotive, motorcycle, printing machinery, industrial robots and construction equipment and other industries.
Japan IKO Dongsheng Co., Ltd. in Japan first started in the needle roller bearings technology development, is a high-quality and product variety of rich fully-known integrated manufacturer.
Needle-shaped needle roller bearings are replaced with thin balls of traditional ball bearings and other rolling bearings. Compared with other rolling bearings, it has the characteristics of small size and light weight and large load capacity. Needle roller bearings, which are resource-saving bearings that can reduce the mechanical size and are miniaturized, have been widely used in automobiles, industrial machinery and office automation equipment and have won high trust.
The characteristics of needle roller bearings can be roughly divided into rolling bearings and plain bearings, rolling bearings according to the type of rolling body can be divided into ball bearings and roller bearings.
Needle roller needle roller bearings for the rolling body into the section height, high precision rolling bearings, has the following characteristics:
The advantages of needle roller bearings
1. Cross-section height is low, can withstand heavy loads
Compared with other rolling bearings, the cross section is low in height and can withstand heavy loads. Therefore, the overall size and weight of the machine can be reduced and the cost can be reduced.
2. Rotation torque is small, improve the efficiency of machinery
Small radius of rotation, so the same friction, the rotation torque can improve the efficiency of small machinery.
3 can reduce the inertia force
Due to the small bearing capacity and quality, it is possible to reduce the inertial force around the bearing during bearing movement.
4 most suitable for swinging movement
Rolling the number of roots, spacing, it is suitable for swinging movement.
The advantages of rolling bearings
1. Starting friction, moving friction is small
The difference between the starting friction and the kinetic friction is small and the friction coefficient is small. Therefore, the driving device can be miniaturized, so that the main body of the machine can be miniaturized and reduced in weight, the cost of the machine can be reduced, and the power cost can be saved.
2. To maintain long-term stability of precision
Due to the small friction, it is possible to maintain stable accuracy over a long period of time.
3. To improve the reliability of machinery
Because of fatigue life prediction based on its life, it improves the reliability of machinery.
4 can simplify the lubrication structure
In most cases, only grease lubrication can fully guarantee their work, it can simplify the lubrication structure, maintenance is also easy.
