Our different diameter ball slewing bearing has three seats ring,the steel balls and the spaces may be directly arranged into upper and lower raceways.two rows of steel balls with different diameters are fitted according to the load.such open mode fiting features are very convenience.the load angles of both upper and lower race are90,which enable the bearingto bear large axial froce and the overturning moment.when the radial force is larger than1/10 of the axial force .the raceways should be especial designed. the axial

The double-row ball slewing bearing The double-row ball slewing bearing has three races. The balls and cages can be directly aligned into the upper or lower raceway. According to force situation, the arrangement is two rows of different diameter balls. This kind of openly assembling is very handy. The loading angles of upper and lower raceways both are 90o. It can take large axial force, and overturning moment. When the radial force is larger than 0.1 times the axial force, its raceway must be designed specially. The double-row ball slewing bearing features bigger axial and radial dimensions, and stable structure. It is especially used for tower cranes with mid-diameter or bigger, and truck-mounted cranes etc loading machinery.

Double-row ball slewing bearing (02 series) 1. Description : The two-row ball slewing bearing has three seat-rings. The steel balls and the retainers may be directly arranged into the upper and lower racers. Two rows of steel balls with different diameters are fitted according to the force. Such open type fitting is extraordinary convenient, the loading angels at upper and lower races are 90 which can carry both of the axial force and capsizing moment. When the radial force is larger than 1/10 of the axial force, the races should be newly designed. 2. Packing 1 Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film; 2 And then packed with craft paper and professional belts; 3 At last, with wooden box totally at the outer packing to invoid the rust or the moist; 4 We can depend on the customers demand to be packed; 3. Features Larger dimension of axial and radial, compact structure. 4. Applications Tower cranes which require working radius over medium range, auto crane and loading (unloading) machinery. Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film;and then packed with kraft paper and professional belts; at last, with wooden box totally at the outer packing to invoid the rust or the moist; we can depend on the customers demand to be packed.

Xuzhou Fenghe Intelligent Technology Co., Ltd. specializes in six types slewing bearings, including single row ball type slewing bearings, double row ball type slewing bearings, three row roller type slewing bearings, single row cross roller type slewing bearings, double line ball type slewing bearings, ball roller combined type slewing bearings.

As a professional triple row cylindrical roller combined slewing bearing manufacturer in China, we mainly provide internal gear type triple row cylindrical roller combined slewing bearings, external gear type triple row cylindrical roller combined slewing bearings and no gear type triple row cylindrical roller combined slewing bearings. Characteristics of Triple Row Cylindrical Roller Combined Slewing Bearing 1. Our triple row cylindrical roller combined slewing bearing has super high carrying capacity. 2. It consists of three bearing rings. The adjusting spacer between upper bearing ring and lower bearing ring can adjust the axial internal clearance. 3. Upper row rollers and lower row rollers are distributed horizontally, so as to support the axial forces and tilting moments from two directions. While radial force is supported by the third row rollers that are vertically distributed. 4. Since our triple row cylindrical roller combined slewing bearing is firm in structure and large in axial dimension and radial dimension, it is quite suitable for use in heavy duty machinery, such as bucket-wheel excavators, wheel cranes, ship cranes, port cranes, molten steel operating platforms, and so on.

High accuracy. High speed. Competitive price. 2. ISO 9001:2008 3. Standard and non-standard deep groove ball bearings. 4. Technology: low vibration, low noise, high precision and durability. 5. 3-7 days for stock order and 10-25 days for production 6. Fast delivery 7. Rich experience in foreign trade SDKF Description: E�?sam[at]sdkf-bearing[dot]com 1. SDKF deep groove ball bearings are the most representative and widely used bearing. It can accommodate axial loads in both directions, in addition to radial loads, even at high speeds. They are available for low noise and low vibration. Bearings with metal shields and rubber seals are pre-lubricated by some grease. Bearing with snap ring and flange on the outer ring. Deep groove ball bearings with filling slots have the same dimensions with standard ones. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots. 2. SDKF shielded deep groove ball bearings: One of the most commonly used bearings, these types are manufactured with shields inserted into the outer raceway, these fit in closely to the inner race providing protection against light mechanical damage, some protection against the ingress of moisture, dust and other foreign matter and serve to retain the pre-filled grease in the bearing. Shields can be easily removed for applications that only require 1 shield Benefits: Provides light mechanical protection, limits moisture and dirt ingress, lubricated for life, cost effective solution 3. SDKF deep groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements. The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation.
