The sealing ring is made of NBR. The oil resistance of the sealing ring is improved, silt, moisture and the like cannot enter the inside of the bearing, the service life of the bearing is prolonged, the use cost is reduced, and the sealing ring is low-temperature resistant, high-temperature resistant and corrosion resistant.

The spring is an annular spring, and the sealing effect of the sealing ring is guaranteed.

The utility model can achieve the following beneficial effects: the utility model has the advantages of reasonable structure, the structure is firm, and intensity is good, and the equipment is convenient, and the anti-oil capability of sealing washer is good, and comprehensive properties is good, inside silt, moisture etc. can not get into the bearing, improved the bearing life-span, reduced use cost, and can be low temperature resistant, high temperature resistant, and can anticorrosive.

Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings.

As shown in fig. 1-3, the present invention is a bearing for a beach vehicle.

The bearing of the dune buggy comprises an outer ring 1, an inner ring 2, a sealing component 3, a steel ball 4 and a retainer 5, wherein the outer ring 1 is in arc transition at the outer end outer diameter, and the inner ring 2 is in arc transition at the outer end inner diameter. The step is established to 1 one end of outer lane, the one end at the step of outer lane 1 and inner circle 2 sets up seal assembly 3, and seal assembly 3 supports and leans on the step face, makes things convenient for seal assembly 3's location and miniaturized bearing's processing. The sealing assembly 3 comprises a stop block 31, a sealing ring 32 and a spring 33, wherein the stop block 31 is of an L-shaped structure, the axial width of the stop block is greater than the radial height of the stop block, the stop block plays a role in supporting the sealing ring, and the sealing ring 32 is of an irregular inverted frame-shaped structure. The sealing ring 32 is sleeved at the upper end of the stop block 31 and wraps the outer side of the stop block 31, the sealing ring 32 is attached to the outer ring 1 in the axial direction, two sealing lips are arranged on the sealing ring 32 in the radial direction, and the two sealing lips are in interference fit with the inner ring 2 respectively.
