The important construction modes of the turntable bearing seat are: four-point contact ball bearing seat, double-row angular contact thrust ball bearing seat, interpenetrating cylindrical roller bearing seat, interpenetrating tapered roller bearing seat, and three-row cylindrical roller with turntable bearing seat.According to whether the gear can be carried and the spread of the gear is divided into: toothless, external or internal gear and other different structures.The four-point contact ball turntable bearing seat has a higher static bearing capacity, the interspersed cylindrical roller be

Linear bearings with flanges Performance: Linear bearings are a linear motion system produced at a low cost for use with unlimited travel and cylindrical shafts. Because the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with minimal friction resistance, thus achieving smooth motion with high precision.

The main features of rotary support bearings include high bearing capacity, fast speed, small friction, wear resistance, simple structure, easy installation and so on. It can withstand large axial and radial loads, while having high rigidity and accuracy, suitable for high-speed rotation and precision positioning requirements. Different types of rotary support bearings have differences in structural form and working principle, such as four-point contact ball type, two-way thrust ball type, cross roller type, tapered roller type and so on.

Tapered roller bearings are suitable for bearing radial loads, unidirectional axial loads and radial and axial combined loads. The axial load capacity of tapered roller bearings depends on the contact Angle α, that is, the Angle of the outer ring raceway, the greater the contact Angle α, the greater the axial load capacity. Generally tapered roller bearings do not allow Angle errors, but the surface of the roller and raceway can be specially designed to allow 2'~4' Angle errors.

THK was founded in 1971 in Meguro-ku, Tokyo, Japan, and was originally named Toho Seiko Co., Ltd. It was later renamed THK CO.,LTD. "THK" stands for "Toughness", "High Quality" and "Know-how".THK linear bearings are a linear motion system produced at low cost for use with cylindrical shafts with unlimited travel. Because the bearing ball is in point contact with the shaft, the load is small.

Advantage of 7020C BearingWhen using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.The locking port of this kind of bearing is on the outer ring.Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction.The ability to bear axial load is determined by the contact angle.The larger the contact angle, the higher the ability to bear axial load.Angular contact ball bearings are mainly divided into single row angular contact ball bearings and double row angula

The single-row four-point contact ball slewing bearing has the characteristics of compact structure and light weight, which makes it widely used in construction machinery. Because the steel ball and the circular raceway contact at four points, this support can bear axial force, radial force and heeling moment at the same time, with high bearing capacity and stability. Applicable scope includes rotary conveyor, welding operator, small and medium-sized cranes, excavators and other construction machinery, is a multi-functional, efficient slewing support structure.

Linear bearings with flanges Performance: Linear bearings are a linear motion system produced at a low cost for use with unlimited travel and circular shafts. Because the bearing ball is in contact with the shaft dry point, the load is small. The steel ball rotates with very little friction resistance, thus achieving smooth motion with high precision.Flanged linear bearing series Specification classification :LME, LMK series LMH series LMFP, LMKP series with flanged linear bearing LMHP series with flanged linear bearing LME.LLMK.L series LMH.L series LMFP...

Product Description:4/8 galvanized steel plate is a half-inch galvanized steel plate, which has high yield strength and tensile strength, and can withstand large tensile, compression and bending forces and is not easy to deformation.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle.

High Rigidity and Stability: miniature angular contact bearings maintain their shape and rigidity when subjected to heavy loads, contributing to enhanced system stability and reduced risk of deformation.Optimized Lubrication Performance: They possess exceptional lubrication characteristics, reducing friction and wear between components, thus extending the bearing's lifespan and ensuring smooth operation.Versatility in Applications: axial angular contact ball bearing are adaptable to various environmental conditions, temperatures, and work environments, making them suitable for a wide range

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.

Single Row Angular Contact BearingsThese single row angular contact bearings are suitable for general use where axial loads are applied in only one direction. They are stand-alone bearings and are not designed to be combined or mated with another bearing.Double Angular Contact BearingsDuplex bearings are two matched bearings that provide precise alignment both radially and axially. By using duplex bearings, vibrations can be eliminated and higher load capacities can be achieved.
