Thrust ball bearings
By a thrust ball bearing steel (with maintains), a shaft (with) and axial tight with a seat ring (and axial clearance and bearing hole is a tight fit), steel shaft and seat ring in between. Can bear a direction of axial load, cannot bear radial load. Because of the axial load is evenly distributed in each ball, so large load capacity, But when the temperature, working, allow lower limit speed. Thrust ball bearings can limit the radial and axial movement, but limited in one direction and shell of axial movement, therefore, such bearing and usually use a combination of deep groove ball bearings.

Cylindrical Roller Bearings
Thrust cylindrical roller bearings are usually combined into a high stiffness bearing configuration, can bear heavy loads without difficulty, and vibration loads. This single-direction bearings can withstand axial load great, but can not bear radial load, they are not self-aligning capability. Thrust cylindrical roller bearings can be split into thrust cylindrical roller and cage assemblies, axle ring and seat ring. Is a separable type bearings. Affordable one-way axial load, can not restrict the radial shaft displacement. Bearing rigidity, small space, the axial load capacity, low sensitivity to impact load. For low speed, thrust ball bearings used in the workplace can not be applied. Installation does not allow the axis of the shaft and housing are tilted.
Cage Type: car solid cage (mostly brass)
Main use: oil drilling rig, iron copper mechanical system
Main structure:
One-way thrust cylindrical roller bearings: for low speed, which can only carry one-way axial load.
Double row thrust cylindrical roller bearings: the kind of roller bearings have two rows of long, short roller staggered, reducing the roller and the sliding friction between the raceway, to ensure a higher carrying capacity, and can increase the speed limit . Can only afford a one-way axial load.

Thrust Spherical Roller Bearings
Thrust roller bearings for main shaft axial load, radial joint load, but the radial load shall not exceed 55% of axial load. Thrust roller bearings other than the low friction coefficient of such bearings, high speed and with self-aligning properties. 29000 non-stick type bearings spherical roller symmetrical type, can reduce the roller and raceway relative sliding at work, and the roller length, diameter, and the number of multi-roller, high load capacity, usually in oil lubrication, Grease can be used for individual low-speed case

Taper roller bearings
Taper roller bearings which mainly bear with radial primarily diameter, the axial union load. Bearing outer ring rolling bearing capacity depends on the way Angle, the larger Angle bearing capacity is bigger. These bearings are of separated type bearings, according to the roller bearing in the column number to be mounted, double row and four row circular cone roller bearings. Single tapered roller bearing clearance to users in when installation, adjustment, Double row and four row circular cone roller bearings clearance already in product factory according to user requirements are given, not the user to resize.
Taper roller bearings taper inner ring and outer ring have groove, tapered roller are arranged in between. All taper surface projection lines are the same point in bearing axis reunion. This design makes tapered roller bearings specially suitable for composite (bear) radial and axial load. Bearing axial load ability is mostly decided by the contact Angle is alpha, Alpha greater perspective, axial load capacity is higher. Angle size by calculating coefficient e to say, E is, the contact Angle is, the bigger the bearing axial load applicability is greater.
Taper roller bearings are usually separated type, namely the belt roller and maintains a module of the inner ring of conical inner ring and outer ring (components can conical outer ring) apart installation.
Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.

Deep groove ball bearings
Deep groove ball bearings, the structure is simple, use convenient to maintain. Mainly used to bear radial load, also can withstand the axial load, when bearing radial clearance increase, with Angle contact ball bearing performance and can withstand the larger axial load. These bearings are small friction coefficient, extreme high speed, size range and forms a variety. Solid and durable, strong commonality and low noise, can be in the running speed operation and easy to install. Single deep groove ball bearings otherwise sealed type design, can no more lubrication and no maintenance. Single belt loaded ball gap and double row ball bearings, applies to heavy work conditions.

Joint bearing is a kind of special structure of sliding bearings. Its structure than rolling bearing simple, its main is by a spherical outside of the inner ring and outer ring inside the ball with a composed, can bear larger load, according to its different type and structure, can bear radial load, axial load or radial, axial and existing joint load. Generally used to speed the lower swing motion (namely Angle motion), with the sliding surface, also can be for spherical shape within the scope of certain Angle for tilt movement (i.e. self-aligning movement), in the axis and shaft shell holes concentricity bigger when, still can work normally. Joint bearing is a kind of special structure of sliding bearings.

Line bearing
Line bearing is a low-cost production linear motion system for endless stroke and cylinder shaft is used together. Due to load the ball and axis is contacts, so using the load is small. Gangqiu the narrowest of friction resistance rotation, thus can get high-precision smooth movement. Straight-line bearing is widely used in electronic devices, tension tester and digital 3d coordinate measurement equipment and other precision equipment, and multiaxial machine, punching machine, cutting machine tools, automatic machine, printer, card sorting machine, ShiPinBao installed the sliding parts such as industrial machinery.

Screw guide
Guide (daogui) and rail: metal or other materials trough or ridge and can withstand, fixed and mobile device or equipment and guide reduce its friction a device. Guide surface on the longitudinal chamfer or ridge, used for guiding, fixed machine parts, special equipment, instruments, etc. Guide in our daily life application is also a popular, such as slip door the slippery mess, train tracks, etc., are guide specific application

Linear guide convergence
A compact structure, strong commonality of miniature linear rolling guide convergence, including miniature slideway, miniature slider, gangqiu, return to implement and maintain the frame, in the micro slide block equipped with mini guide cross-section shape phase adapter grooves, in both sides of the grooves and miniature guide sides respectively a row of reciprocal groove, load bearing of steel ball set in rolling within the tao, miniature slider through ball Settings in the micro guide rail and can move along the micro axial guide rail, used to make steel ball turned to return to implement fixed in the micro slider both ends of the miniature slider and return to implement all by maintains a fixed. The utility model design has two rows of gothic double-arced groove, installation of small size, high precision, large applied to light load cases. It is especially applicable to measuring equipment, computer embroidery machine, precision machinery, electronics, machinery, carved occasions, medical equipment is of great practical value and the market prospect

Spherical bearing outside
The component of the spherical surface bearing outer ring has spherical diameter of bearings, and the concave spherical inner hole bearing suitably, have, suitable for automatically adjustable cardiac function, flexibility larger rigid sent general axis. The bearing with seals at both closely, can prevent sewage invasion. In the factory apply already loaded into the lubricant, before the installation, do not need to clean. In allowing the lubrication period, without adding lubricant. Bearing inner circle the top side of the projection on the axle wire screws, allowed strong axial load not exceed 20% of the dynamic load.
