Linear Motion Bearings

Abstract

The invention discloses a linear motion bearing, comprising a support (3) and a rolling body (4), wherein an upper seat retainer (1) and a lower seat retainer (2) are mounted on the support (3); openings (9) fitted with the shapes of the upper part and the lower part of the support (3) are respectively formed in the middle parts of the upper seat retainer (1) and the lower seat retainer (2); the upper seat retainer (1) is sleeved on the upper part of the support (3); the lower seat retainer (2) is sleeved on the lower part of the support (3); the top surfaces of the upper seat retainer (1) and the lower seat retainer (2) are respectively provided with an annular groove which is fitted with the shape of the rolling body (4); the rolling body (4) can be arranged between the upper seat retainer (1) and the lower seat retainer (2) in a rolling manner; the side of the rolling body (4) can be arranged on a waist type hole shaped periphery of the support (3) in a rolling manner; and a housing (5) is arranged on one side of the rolling body (4). The linear motion bearing disclosed by the invention has the advantages that the rolling body is further fixed; the structure of the linear motion bearing is firmer; the linear motion bearing can be used on a sliding body separately, and is reasonable in structure and artful in design; and the application range is effectively enlarged.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to a linear motion bearing. Background technique [0002] A linear motion bearing is a linear motion system produced at low cost for infinite formation for use with cylindrical shafts. Since the bearing ball is in point contact with the shaft, the operating load is small. Steel balls rotate with minimal frictional resistance, resulting in smooth motion with high precision. In rolling bearings, the bearing rings are separated by rolling elements, and in sliding guide systems, the movable part slides on a static guide or shaft. Depending on the type of rail system, the sliding level is on movable or rigid components. Lubricating oil is embedded in the sliding layer to achieve the purpose of lubrication. The sports bearing in the prior art, because there is no casing around the bearing, is less stable, not only the firmness cannot be guaranteed, but also the movement of ...

AI Technical Summary

Problems solved by technology

The sports bearing in the prior art, because there is no casing around the bearing, is less stable, not only the firmness cannot be guaranteed, but also the movement of the bearing due to the heavy load often occurs during the use of the sports bearing. The bearings are worn out, and there is an unstable state during the movement
