POM composite bushing and strips
Like PTFE composite bearings, POM composite bearings also have a sheet steel backing thatof these bearings is their relatively thick (0,3 mm) layer of acetal resin (POM– polyoxymethylene)
that is firmly attached to the sintered tin/bronze layer. The covering layer has pockets to retain
grease. The thickness of the covering layer makes these bearings less sensitive to misalignment
Bearing Life, Design, and service life estimate
Many years of goal-oriented research and development work have resulted in excellent sliding materials that cover a wide range of applications featuring maintenance-free or low maintenance operations. The type and design of bearing to be used for a given application have to be chosen with respect to the type of load acting upon the bearing, the operating temperature which can be expected, and the requirements regarding lubrication and maintenance.
Flanged bushings are manufactured to
the same tolerances as plain bushings.
A deviation of ± 0.5 mm (0.02 in) applies to the flange
diameter D1 when mounted.
What should be paid attention to when using composite bearings
1. Keep the bearing and its surroundings clean. Even if invisible dust enters the bearing, it will increase wear, vibration and noise of the bearing.
2. Two, the use of the device should be careful, do not allow strong stamping, do not allow the hammer directly hit the bearing, do not allow pressure transmission through the rolling body.
3. Use appropriate and accurate installation tools, use special tools as far as possible, and make every effort to prevent the use of such things as cloth and staple fibers.
4. to avoid the bearing corrosion, directly take the bearing by hand, to wash the hands of the sweat, and coated with high-quality mineral oil before stopping the operation, in the rainy season and summer to pay special attention to rust. However, under certain special operating conditions, the bearing can achieve a better life than the conventional calculation, especially under light loads. These special operating conditions are the appearance damage that may occur when the rolling surfaces (tracks and rolling elements) are effectively separated and restricted by a smooth oil film. In fact, under ideal conditions, the so-called permanent bearing life is possible.
5. Bearing service life, rolling bearing life in revolutions (or the number of hours worked at a certain speed), defined as within this life, a bearing shall undergo initial fatigue damage (spalling or defect) on any of its bearing rings or rolling body. However, no matter in laboratory experiments or theoretical application, it can be clearly seen that the bearing with the same appearance under the same working conditions has different theoretical life. In addition, there are several different definitions of the “life” of a bearing, one of which is the so-called “working life”, which means that the theoretical life of a bearing that can be reached before damage is caused by wear, the damage is usually not caused by fatigue, but by wear, corrosion, seal damage and other reasons.

Bushing Tolerances
The tolerances for the outside diameter of the metric bushings correspond to the values given in ISO 3547 Part 1. To check these tolerances the method outlined in ISO 3547 Part 2 should be followed. The maximum and minimum wall thickness values for metric bushings can be found in our catalog. The tolerance for the bushing width B is a uniform ±0.25 mm (±0.01 in).
Machining the bore of POM composite bushings
Bushings made of POM composite material are ready for installation. However, if necessary, the bushing bore can be machined to size while mounted in its housing. After machining the bore, the sliding surface should have a Ra value of max 2,5 μm. The following machining recommendations will provide good results when a polycrystalline diamond
the cutting tool is used
• cutting speed > 150 m/min
• slow feed rate (0,05 to 0,1 mm/revolution)
• cutting depth 0,1 mm.
To prevent excessive heat build-up of the acetal resin, and to remove the swarf produced during machining, a constant supply of compressed air (at low pressure) should be applied to the bushing during any machining operation.
