Single row crossed roller slewing bearing – 11 series
Single row crossed roller slewing bearings consist of two seat rings. They feature a compact structure, light weight, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross pattern, enabling them to simultaneously withstand axial force, tilting moment, and large radial force. They are widely used in lifting and transport, construction machinery, and military products.

Detials
1. Oil Hole: “n1” represents the number of lubricating oil holes. To facilitate maintenance operations on your equipment, the specific location of the oil holes can be designated according to your actual application requirements. (Grease nipple M10×1, execution standard: JB/T 7940.1 to JB/T 7940.2)
2. Threaded Hole: “n-∅” indicates the mounting holes, which are through-holes by default. These can be modified to threaded holes based on your installation and fastening scheme (threaded hole diameter M, thread depth 2M).
3. Dimensional Tolerance: The product specifications in the table represent standard products. Both inner and outer diameters follow standard commercial tolerances. If your host equipment has specific fit requirements with the slewing bearing, please state them clearly so we can customize production for you.
4. Non-Standard Customization: The list contains our standard product series. We fully understand the unique requirements of different application scenarios. Whether you require a special structural design, dimensions, material specifications (e.g., low-temperature resistance, corrosion resistance), higher precision classes, or any other non-standard customization, our engineering and technical team can provide professional solutions.
