AI Technical Summary
Existing plane bearings are prone to shaking and skewing when subjected to large radial forces, affecting the bearing life and the stability and precision of mechanical equipment.
The double steel ball design, including the first large steel ball and the second large steel ball, combined with the structure of the limit ring and tiny steel balls, ensures that the flat outer ring remains stable during rotation, and the design of the limit ring groove avoids the reaction force on the contact surface of the steel balls that hinders rolling.
It improves the stability and load-bearing capacity of the plane bearing, reduces rolling resistance, and can withstand larger radial loads.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a high radial force plane bearing. Background Art
[0002] The radial force of a bearing refers to the force acting in the radial direction inside the bearing. In a bearing, the radial force affects the life and stability of the bearing. When the radial force increases, the load on the bearing also increases, which shortens the life of the bearing and causes deformation and vibration of the bearing, affecting the stability and precision of the mechanical equipment.
[0003] Plane bearings are one of many types of bearings. Existing planar bearings consist of a cage with steel balls embedded inside and outer rings flanking the cage. This simple overall structure makes the outer rings susceptible to vibration on either side of the cage, making them unable to carry large radial loads. To address this issue, we propose a high-radial-force planar bearing. Utility Model Content
