Definition of self-lubricating ball joint bearing

Ball joints are the pivot between the wheels and the suspension of an automobile. Ball joints play a critical role in the safe operation of an automobile's steering and suspension. Ball joints can also be found in most linkage systems for motion control applications, and should not be confused with spherical rod end bearings, which are a different design.

Sealed ball joints do not require lubrication as they are "lubed for life" but standard ball joints must be lubed from time to time. It's best to inspect standard ball joints once a year. Generally speaking, standard ball joints will outlive sealed ones because eventually the seal will break, causing the joint to dry out and rust. While there is no exact lifespan that can be put on a sealed ball joint, they can fail as early as 80,000 miles. Signs of a failing ball joint start with a clicking or snapping sound when the wheel is turned and eventually turns into a squeaking sound at the end of a stop, when the gas pedal is used and/or also when hitting bumps. Another symptom could be 'thud' noises coming from front suspension when going over bumps.

If a ball joint fails, the results can be dangerous as the wheel's angle becoming unconstrained, causing loss of control. Because the tire will be at an unintended angle, the vehicle will come to an abrupt halt damaging the tires. Also, during failure, debris can damage other parts of the vehicle.

Joint bearings can bear larger load. According to their different type and structure, can bear radial load, axial load or the radial, axial co-existing union load. Because of the sphere, circle with composite materials, reason this bearing in the work can produce self-lubrication. Commonly used for low speeds swinging movement, and low speed rotating, also can be in certain Angle range be tilted movement, when supporting shaft and axis shell hole concentricity bigger when, still can work normally. Self-lubricating joint bearings used in water conservancy, specialized mechanical industries.

Self-lubrication ball joint bearings classification and features:

1. To the heart joint bearings

(1) GE... E model sheet, no lubrication oil every outer ring. Can bear radial load and any direction of smaller axial load.

(2) GE... ES type single-slit invading.this, lubrication oil groove. Can bear radial load and any direction of smaller axial load.

(3) GE... ES - 2RS type single-slit invading.this, lubrication oil groove, with seals at both. Can bear radial load and any direction of smaller axial load.

(4) GEEW... ES - 2RS type single-slit invading.this, lubrication oil groove, with seals at both. Can bear radial load and any direction of smaller axial load.

(5) GE... ESN type

Single slit outer ring, have lubrication oil groove, outer ring have check dynamic slots. Can bear radial load and any direction of smaller axial load. But the axial load by stop ring inherit, its axial load capacity reduction.

(6) GE... XSN type

A double-slit outer profile especially circle (), there is lubrication oil groove, outer ring have check dynamic slots. Can bear radial load and any direction of smaller axial load. But the axial load by stop ring inherit, its axial load capacity reduction.

(7) GE... HS type lubrication oil groove, inner ring has double half invading.this, after wearing clearance can be adjusted. Can bear radial load and any direction of smaller axial load.

(8) GE... DE1 type

Inner ring for hardened bearing steel, outer ring for bearing steel. Inner circle assembling extrusion, lubricating oil and oil hole. Inner diameter less than 15mm bearings, no lubrication oil and oil hole. Can bear radial load and any direction of smaller axial load.

(9) GE... DEM1 type

Inner ring for hardened bearing steel, outer ring for bearing steel. Inner circle assembling extrusion, bearing load bearing outer ring pressed, after the end ditch makes bearing axial fixation. Can bear radial load and any direction of smaller axial load.

(10) GE... DS type

Outer ring have assemble slots and lubricating slots. Limited to large size bearings. Can bear radial load and any direction of smaller axial load (assembly slot side can not bear the axial load).

2. Angular contact joint bearings

GAC... S-type inside and outside circle were hardened bearing steel, outer ring have tanks and oil hole. Can bear radial load and a direction (joint) axial load.

3. Thrust joint bearings

GX... S-type shaft lap and seat ring are hardening bearing steel, Seat ring have tanks and oil hole. Can bear a direction of axial load or combined load (right now the radial load value nor larger axial load value of 0.5 times).

4. Fixed-end joint bearings

(1) SI... E type is GE... E type bearings and pole terminal assembly body. With female threaded rod ends, materials for carbon steels, No lubrication oil groove. Can bear radial load and any direction less or equal 0.2 times radial load of the axial load.

(2) SA... E type is GE... E type bearings and pole terminal assembly body. Fixed-end out-of-band thread, materials for carbon steels, No lubrication oil groove, can bear radial load and any direction less or equal 0.2 times radial load of the axial load.

(3) SI... ES type is GE... ES type bearings and pole terminal assembly body. With female threaded rod ends, materials for carbon steels, Have lubrication oil groove. Can bear radial load and any direction less or equal 0.2 times radial load of the axial load.

(4) SA... ES type is GE... ES type bearings and pole terminal assembly body. Fixed-end out-of-band thread, materials for carbon steels, Have lubrication oil groove. Can bear radial load and any direction less or equal 0.2 times radial load of the axial load.

(5) SIB... S-type with female threaded rod ends, materials for carbon steels, Inner ring for hardened bearing steel, Have lubrication oil groove. Can bear radial load and any direction less or equal 0.2 times radial load of the axial load.
