LYNBCC cross cylindrical roller slewing bearing can carry axial load, tilting moment and radial load all at the same time. The design and application of the cross cylindrical roller slewing bearings are basically the same as those of the four point contact ball slewing bearing, except that the rolling elements are substituted from balls into rollers and the contact way between the rolling elements and rings is changed from point contact into line contact. Those changes allow for the carrying capacity to be increased, but the wear and the friction moment load are also increased.

LYNBCC cross cylindrical roller slewing bearings are composed of a inner ring, outer ring, a single row of rollers, cages(spacer), and seal device etc.

In this design, their cylindrical rollers in axial direction is cross-distribution. The length-diameter ratio of cylindrical roller is less than1, It would cause slight movement when rollers running.

LYNBCC cross cylindrical roller slewing bearing can carry different combined forces caused by axial load, tilting moment and radial load in different working condition. By adjusting the quantity of crossed rollers and contact angle.

There are integral and separate rings in the structure of LYNBC cross cylindrical roller slewing bearing. Cages or spacers are usually adopted within design in order to ease friction. Rollers and raceway contact.

This slewing bearing with a design of a full complement of rollers is mainly applied in the condition where a heavier axial load is the primary load, and the requirement for tilting moment and friction moment is not so high.

The basic structure of LYNBC cross cylindrical roller slewing bearing as below:

Without gear

External gear

Internal gear

▲ The design’s of all these slewing bearing are based on standard structures; LYNBC can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNBC Technical Center if you need any assistance in this area.

Selection Criteria

Choosing the right cross roller slewing bearing for a specific application involves several factors:

Load Requirements

Axial Load (Fa): The maximum axial load the bearing will experience.

Radial Load (Fr): The maximum radial load the bearing will experience.

Moment Load (M): The maximum moment load the bearing will experience. This is often the most critical factor.

Consider static loads (non-rotating) and dynamic loads (during rotation).

Factor in any impact loads or shock loads.

Rotational Speed: The maximum rotational speed of the bearing.

Accuracy Requirements: The required level of rotational accuracy. This will influence the choice of preload and manufacturing tolerances.

Operating Environment

Temperature: The operating temperature range.

Contamination: The presence of dust, dirt, or other contaminants.

Corrosion: The potential for corrosion.

Vibration: The level of vibration.

Mounting Conditions

The stiffness of the supporting structure.

The accuracy of the mounting surfaces.

The method of mounting (e.g., bolted connections).

Bearing Size and Weight: Physical space constraints and weight limitations.

Lifespan Requirements: The desired lifespan of the bearing.

Lubrication: The type of lubricant to be used and the lubrication frequency. Consider grease lubrication or oil lubrication, and whether automatic lubrication systems are needed.

Sealing: The type of sealing required to protect the bearing from contamination.

Preload: The amount of preload required for the application. Higher preload increases stiffness and accuracy but also increases friction.

Material: Selecting the appropriate material based on load, environment, and cost considerations.

Special Features: Consider any special features that may be required, such as integrated gears, sensors, or encoders.
